Dual Circularly Polarized Substrate Integrated Waveguide Cavity-Backed Antenna with Enhanced Bandwidth and Reduced Size for Wideband Wireless Applications

cavity backed antenna array has been proposed, in which SIW structure are used for feeding network [11]. Although SIW feeding network provides low loss

The dual-band dual-sense polarization based antenna structures reported in [19, 20] are composed of an L-shaped radiating patch and modified ground plane.. Since only a few studies

Abstract —A single-fed compact circularly polarized quarter-mode substrate integrated waveguide (QMSIW) antenna with improved bandwidth is designed based on a single-layer

The VP antenna is composed of a circular ground plane, a cross-shaped metal patch with four shorted legs and a top-loading circular ring.. The printed dipoles of the HP antenna are

In this paper, a single-feed dual-band dual-sense circularly polarized microstrip antenna that utilizes a circular radiating patch with a ring slot has been proposed.. By

A novel single-feed microstrip patch antenna comprising a square patch with four symmetrical C-slots and a slit embedded is demonstrated to generate good dual-frequency

The antenna adopts a two-layered stacked structure, in which a diagonally positioned rectangular patch is used as the driven part, and capacitively-loaded patch-based crossed
