A Review of Micro-strip Patch antenna for UWB Frequency Range

Since 1970s the micro-strip antenna in use, primarily it is used for in space technologies [1]. But over the last few years the micro-strip patch antenna is a topic of intense investigation because this technology has many advantages and better future aspects [3]. Some popular advantages of these types of antennas are light weight, smaller size and its lesser volume. These antennas can be easily molded to any desired structure and easily linked to any host surface because of their conformal structures of low profile planar configuration. Similarly we can say that their construction processes are very simple, production of these antennas also so simple and easy, and the major advantage of MPA is low cost. The fabrication process of micro-strip patch antenna is suitable with MMIC (microwave monolithic integrated circuit) and OEIC (optoelectronic integrated circuit) technologies. These types of antennas are efficient with single, dual, triple and multi frequency operations. By using

Design Techniques for Elliptical Micro Strip Patch Antenna and Their Effects on Antenna Performance

Design Techniques for Elliptical Micro Strip Patch Antenna and Their Effects on Antenna Performance

generate amorphous shaped micro-strip patch antenna designs from ellipses [37]. This automatic shape creation technique was applied to develop four different designs of tri-band patch antenna, broadband patch antenna, GSM compatible dual-band monopole embedded in a dielectric and broadband monopole. Multiple number of ellipses were arranged to create the shape of antenna in which the optimization of location parameters and geometry parameters of these ellipses were carried out using the GA. The „x‟ and „y‟ co-ordinates of centre of ellipse were the location parameters and the radii in „x‟ and „y‟ directions were the geometry parameters. The ellipses overlapped to generate amorphous designs. Models were created using the parameter values provided by the GA programme and these models were passed on to the commercial programme QFDTD for simulation. These models were ranked based on their values for the cost function and thus optimized models were developed. The authors have claimed that the design using ellipses was simple to implement and produced wider bandwidths and less reflection loss than many previous methods.

Double-Elliptical Shaped Miniaturized Micro Strip Patch Antenna for Ultra-Wide Band Applications

Double-Elliptical Shaped Miniaturized Micro Strip Patch Antenna for Ultra-Wide Band Applications

Abstract—Greater design flexibility and newer miniaturization techniques are highly sought after by the commercial antenna industry and researchers. Micro-Strip Patch Antenna (MSPA) is finding huge applications in various fields of communication. In the present paper, the novel idea of Double- Elliptical Micro-strip Patch Antenna (DEMPA) is proposed for antenna miniaturization and higher design flexibility. Double-Elliptical Patch (DEP) is made as the combination of two half-elliptical patches having the same minor axis and different semi-major axes or the same major axis and different semi-minor axes. A DEP with different lengths of horizontally arranged semi-major axes and centrally given feed was considered here. The length of semi-major axis for right half-elliptical patch was varied while keeping the length of semi-major axis for left half-elliptical patch fixed. Design of DEMPA was carried out using Ansoft HFSS software, and the antenna has been fabricated and tested. The measured results were in good agreement with the simulated ones. The percentage reduction in effective patch area was found to be 8.33 for DEMPA compared to the corresponding elliptical patch antenna. The DEMPA covered the entire frequency range of Ultra Wide Band (UWB). With this novel shape, greater design flexibility along with miniaturization is achieved. The axial ratio analysis showed that the resulted antenna was of linear polarization.

Design & Analysis of 8GHz X-Band Micro-strip Patch Antenna

Design & Analysis of 8GHz X-Band Micro-strip Patch Antenna

ABSTRACT: The study of micro strip patch antennas has made great progress in recent years. Compared with conventional antennas, micro strip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the micro strip patch antennas can provide dual and circular polarizations, dual-frequency operation, frequency agility, broad band-width, feed line flexibility, and beam scanning omnidirectional patterning. In this paper we discuss the micro strip antenna, types of microstrip antenna, feeding techniques and application of micro strip patch antenna with their advantage and disadvantages over conventional microwave antennas. We simulated for radiation pattern up to 1.8. Our antenna height 2.88 mm after simulation we got frequency 2GHz. From simulation patch antenna resonating at 1.8 having a return loss of -12.5dB and those -3dB and -10dB bandwidths are 0.74GHz and 0.25GHz, due to the reason that the radio amplifier reduces the output power, can be more worse and can become unstable if the VSWR is large.

Here, the proposed idea is to model the micro strip antenna with new material for substrate having very high dielectric constant. The basic idea of this paper is to get the desired functioning of micro strip patch antenna with less size with respect to height and width of the substrate as well as the patch with the use of ceramic substrate. The substrate used in this design is belongs to ceramic family which is named by forsterite. By using this ceramic family substrate efficient and concise antenna is designed.

Enhancement of Bandwidth Using U Slot Micro strip Patch Antenna Operating at TM02 Mode

Enhancement of Bandwidth Using U Slot Micro strip Patch Antenna Operating at TM02 Mode

Indoor wireless links have intrinsic characteristics that affect the system performance, such as the multipath effect that causes signal fading, and interference effect from adjacent cells that degrades the bit error rate. From the physical layer perspective, one solution to combat these impairments is the use of directional antennas rather than the traditional omnidirectional ones [1]. They have the ability to confine the power in certain directions instead of scattering the power everywhere. As a result of less power loss toward unwanted directions, the multi-path and interference effects are reduced. Directional antennas can be single or dual/multi- beam. Dual/multi-beam antennas are antennas that have more than one directive beam from a single aperture. These antennas are useful for indoor wireless systems which require coverage of multiple areas [2], as they reduce the required number of antennas and are found to improve the link quality [3], resulting in easier net-work deployment. Micro-strip antennas have been widely used in many modern communication systems, because of its robustness, planar profile, and low cost. Most of these antennas operate at their fundamental mode, which gives a broadside beam [4]. Micro-strip antenna operating at the higher order mode has dual symmetric radiation beams, with each beam directed at respectively [5]–[7]. It is well known that the major drawback of a micro-strip antenna is its narrow bandwidth (3%). One of the popular techniques for broadening the patch antenna bandwidth is to incorporate a U-slot on its surface as proposed in [8] and [9]. However, the U-slot technique was studied only at the Fundamental mode of the patch [10]. To the best of authors’ knowledge, there is no published report on the study of the U-slot patch Antenna excited at the higher order mode.

Design of Millimeter Wave Micro strip Patch Antenna for MIMO Communication

Design of Millimeter Wave Micro strip Patch Antenna for MIMO Communication

Multi-user MIMO (MU-MIMO) is a set of multiple- input and multiple-output technologies for wireless communication, in which a set of users or wireless terminals, each with one or more antennas, communicate with each other. In contrast, single-user MIMO considers a single multi- antenna transmitter communicating with a single multi- antenna receiver. In a similar way that OFDMA adds multiple access (multi-user) capabilities to OFDM, MU-MIMO adds multiple access (multi-user) capabilities to MIMO. MU- MIMO has been investigated since the beginning of research into multi-antenna communication, including work by Telatar on the capacity of the MU-MIMO uplink.SDMA, massive MIMO, coordinated multipoint (CoMP) and ad hoc MIMO are all related to MU-MIMO; each of those technologies often leverage spatial degrees of freedom to separate users.Multi-user MIMO (MU-MIMO) can leverage multiple users as spatially distributed transmission resources, at the cost of somewhat more expensive signal processing.

Broad  Band Micro strip Patch Antenna Design a Critical review

Broad  Band Micro strip Patch Antenna Design a Critical review

impedance matching, consistent omni directional radiation patterns and appropriate gain characteristics (>2.5 dBi) in the RFID and WLAN frequency regions [11]. “Mohammad Ojaroudi” has presented a novel, compact printed monopole antenna (PMA) for UWB applications. The antenna designed and then fabricated meets out the requirement of an ideal antenna at -10 db.The feed-gap distance, the sizes of Tshaped notch, and the sizes of two rectangular slots in the antenna’s patch is used to obtain the wide bandwidth have been optimized by parametric analysis. This antenna exhibits good radiation behaviour within the UWB frequency range. [12]. “ Y. Chen”, has proposed Design And Analysis Of Wideband Planar Monopole Antennas Using The Multilevel Fast Multipole Algorithm. In this to analyze the impedance bandwidth and radiation performance of the monopoles a full-wave method of moment (MoM) based on the electric field integral equation (EFIE) is applied. Meanwhile, to reduce the memory requirements and computational time, the multilevel fast multipole algorithm (MLFMA) is employed. Two wideband planar monopoles attached to finite sized ground planes are designed, analyzed, and fabricated. Both of the simulated and measured results shows that the two monopoles are capable to cover the AMPS, GSM900, and DCS band. In the whole operating frequency, both of the monopoles can provide a nearly omni-directional radiation pattern in the azimuth plane [13]. “Nakchung Choi” has proposed a notch-frequency band for a UWB antenna which can be embedded into laptop computers with an I-shaped parasitic element. This novel band-notched UWB antenna has the capability to provide easy tuning of the notch-frequency function and bandwidth with good stop band rejection [14,15, 16].

Design Simulation and Performance Analysis of Strip-Line Feed Rectangular Micro-Strip Patch Antenna

Lastly, substrate thickness is another important designparameter. Thick substrate increases the fringing field at the patch periphery like low dielectric constant and thus increases the radiated power. The height of dielectric substrate (h) of the microstrip patch antenna with stripline feed is to be used in C-band range frequencies. Hence, the height of dielectric substrate employed in this design of antenna is h=1.6 mm.

EFFECT OF EXCITATION TECHNIQUES ON THE RADIATION PARAMETERS OF MULTIBAND MICROSTRIP PATCH ANTENNA: DESIGN AND ANALYSIS

Micro strip patch antenna’s excitation techniques can be classified into two types- contacting and non-contacting. In the contacting method, RF power is fed directly to the radiating patch using a connecting element. In the non-contacting scheme, electromagnetic field coupling is done to transfer power between the micro strip line and the radiating patch [9].

Bandwidth Enhancement Techniques using Stacked Microstrip Patch Antennas

Bandwidth Enhancement Techniques using Stacked Microstrip Patch Antennas

Figure 3: Common shapes of micro strip patch elements Microstrip patch antennas radiate primarily because of the fringing fields between the patch edge and the ground plane. For improving the antenna performance a thick dielectric substrate having a low dielectric constant is desirable since it gives a good efficiency, widebandwidth and better radiation pattern but such configuration leads to a larger antenna size. So in order to design an optimized micro strip patch antenna the substrates with higher dielectric constants must be used which are less efficient and result in narrower bandwidth. Hence there must be trade-off between the antenna dimensions and antenna performance.
