Broadband Stacked Patch Antenna with Low VSWR and Low Cross-Polarization

A low cross-polarization broadband stacked patch antenna is proposed By means of the stacked patch configuration and probe-fed strip feed technique, the VSWR 1.2:1 bandwidth of the patch antenna is enhanced to 22% from 804 MHz to 1,002 MHz, which outperforms the other available patch antennas (<10%). Furthermore, the antenna has a crosspolarization level of less than -20 dB and a gain level of about 9 dBi across the operating bandwidth. Simulation results are compared with the measurements, and a good agreement is observed.
