A Comact Microstrip Patch Antenna for Wireless Communication

A Comact Microstrip Patch Antenna for Wireless Communication

In recent years demand for small antennas on wireless communication has increased the interest of research work on compact microstrip antenna design among microwaves and wireless engineers [1–6]. To support the high mobility necessity for a wireless telecommunication device, a small and light weight antenna is likely to be preferred. For this purpose Compact Microstrip antenna is one of the most suitable application. The development of antenna for wireless communication also requires an antenna with more than one operating frequency.This is due to many reasons, mainly because there are various wireless communication systems and many telecommunication operators using various frequencies. Therefore one antenna that has multiband characteristic is more desirable than having one antenna for each frequency band. To reduce the size of the antenna one of the effective technique is cutting slot in proper position on the microstrip patch.

Microstrip Patch Antenna

Microstrip Patch Antenna

vii ABSTRACT This project is about to design of a microstrip patch antenna on the non- conductive textile substrates at the operating frequency 2.45 GHz which is for wireless local area network (WLAN) application. There are certain fabric materials in the market that can be use to patch the microstrip antenna such as Nora, felt, fleece and etc. Those fabric materials have relative permittivity characteristics that make it suitable for wearable antenna. The main objective of this project is to design, simulate, fabricate and analyze the microstrip patch antenna at frequency 2.45 GHz using textile as the substrate. The proposed fabric material for this project is felt fabric. The felt fabric is selected because it has constant thickness and stable relative permittivity. The 2.45 GHz unlicensed band is utilized for the development of this wearable antennas. The used of FR4 as the substrate in conventional antenna is not suitable for wearable system because of limited body movement problem. To overcome this problem is by changing FR4 substrate with textile substrate. The measurement results for fabricated antenna have a slightly different with the simulation result. The frequency of the simulation result is 2.45 GHz, but the frequency of measured result has shifted to 2.6 GHz. However, some recommendation was made in order to improve the performance of the antenna.

Analysis And Design Of Microstrip Patch  Antenna For Wireless Applications

Analysis And Design Of Microstrip Patch Antenna For Wireless Applications

Keywords – Microstrip, WiMax, WLAN, VSWR I. Introduction Antennas are needed for every transmitter and receiver whether in either hidden form or protected as in radio and laptops which are equipped with Wi-Fi or in some other common systems. An antenna is also defined as the transformational structure between the guiding space and free space. The main use of radio transmitters and radio receivers is to carry signals or data towards the systems which includes Wi-Fi, remote controlled instruments and point to point transmission links. All systems would require an antenna that is non bulky and occupies less space. One such antenna is Microstrip Patch Antenna. A microstrip antenna generally consists of a dielectric substrate sandwiched between a radiating patch on the top and a ground plane on the other side. The patch is generally made of conducting material such as copper or gold and can take any possible shape. The dielectric constant of the substrate Є is typically in the range 2.2 ≤ Є ≤ 12. [1-13]. Various types of antennas are proposed to cover these frequency bands, such as dipole, monopole, dielectric resonator antenna (DRA), patch, and planar inverted-F antenna (PIFA). In this paper, we propose a single band antenna fully covering WiMax bands (10.5 GHz). And also the antenna has designed with the filter in order to allow the required frequency and to remove the noise &

MIMO technology has attracted attention in wireless communications, because it offers significant increases in data throughput and link range without requiring additional bandwidth or transmit power, higher spectral efficiency and reduced fading. Because of these properties, MIMO is an important part of modern wireless communication standards such as IEEE 802.11n (Wifi), IEEE 802.16e (WiMAX), 3GPP Long Term Evolution (LTE), 3GPP HSPA+, 4G and 5G systems to come.

Multi-Slotted Microstrip Patch Antenna for Wireless Communication

Recently, an E-shaped patch antenna [11] and U-slotted patch antenna [12] have been designed for wireless communications. However, both of these patch substrate are non inverted and achievable gains of both antennas are below 8.5 dBi.

U-Slot Microstrip Patch Antenna for Wireless Application

U-Slot Microstrip Patch Antenna for Wireless Application

FIG 1 – MICROSTRIP PATCH ANTENNA In order to achieve effective radiation of antenna, the designed antenna must have a substrate of low dielectric constant therefore RT duroid is chosen and which results in the better performance of antenna and provides better efficiency, larger bandwidth and better radiation with reduced number of side lobes.The dielectric constant for the RT duroid 5880 is 2.2, which is comparatively smaller than the other substrates.The input is given using different feed techniques and different feeding methods are available to feed microstrip patch antenna. The radio frequency power is fed directly to the radiating patch using microstrip line feed method. There are many feeding techniques, which includes microstrip line feed, coaxial line feed, aperture coupling and proximity coupling method. In the microstrip line feed, a conducting strip is connected directly to the center of the patch by etching the substrate and the conducting strip should be smaller in width when compared with the width of the microstrip patch. The inset cut is made in the patch to increase the radiation of the antenna.

Development of microstrip patch antenna strain sensors for wireless structural health monitoring

Development of microstrip patch antenna strain sensors for wireless structural health monitoring

161 effect of Poisson’s ratio into account, the other axis of the circular patch was compressed by one third of the applied strain; resulting in an ellipse which is depicted in Figure 8.21. The resultant ellipse patch was added to the top of the substrate instead of the circular patch and the same simulation was conducted to derive the S11 curve of the horn antenna. The comparison of the return loss for these two scenarios is illustrated in Figure 8.22 where the frequency range is 1.5 GHz to 1.6 GHz to only include the resonant frequency of the CMPA. This figure shows that the resonant frequency of the patch (measured wirelessly by the horn antenna) shifts toward lower frequencies. This behaviour is similar to the patch antenna fed by a coaxial cable which is explained in previous chapters. These results encouraged the author to further investigate the wireless strain measurement by experimental tests which are described in the following subsection.

microstrip patch antenna design

In the past few years, the interest in the millimeter-wave spectrum at 30 to 300 GHz has drastically increased. The emergence of low cost high performance CMOS technology and low loss, low cost organic packaging material has opened a new perspective for system designers and service providers because it enables the development of millimeter-wave radio at the same cost structure of radios operating in the gigahertz range or less. In combination with available ultra- wide bandwidths, this makes the millimeter-wave spectrum more attractive than ever before for supporting a new class of systems and applications ranging from ultra-high speed data transmission, video distribution, portable radar, sensing, detection and imaging of all kinds. This section presents some novel DRAs of relatively simple design, which have demonstrated millimeter band performance, and may serve as suitable antenna candidates for these various applications.
