Abstract

A new wideband dual-polarized patch antenna consisting of a magnetically-fed and an electrically-fed is presented in the paper. The two feeds are orthogonal to each other at the center of the ground plane and generate 0° and 90° polarization separately. Two pairs of L-shaped slots are etched in the radiating patch to improve the impedance bandwidth. By using a shorting pin connecting the radiating patch to the ground plane, the coupling between the two feeding ports can be reduced. With the help of circuit simulation and full wave simulation, the equivalent circuit model of the antenna is established. The simulated and measured results show that the impedance bandwidths for VSWR less than 2 of the proposed dual-polarized antenna with a profile of are 27.3% (3.29-4.33 GHz) and 19% (3.05-3.69 GHz) for 0° polarization and 90° polarization, respectively, with a height of 0.08 λ₀ between radiating patch and ground plane. The measured coupling between the two ports is below -20 dB over the operating band. Moreover, the measured gain of the proposed antenna is about 7.9 dBi and 6.1 dBi for port 1 and port 2, respectively, over the operating band. Measured results of the fabricated antenna prototypes are in good agreement with the simulated results.
