A Wideband Antenna With Dual Printed $L$-Probes for Cross-Polarization Suppression

A multilayered patch antenna for wideband and low cross-polarization operation is proposed. By introducing a pair of printed $L$ -probes, the high cross-polarization levels are significantly suppressed across a wide bandwidth of 45.2% for voltage standing-wave ratio (VSWR)< 2$. In addition, symmetrical and stable radiation patterns are achieved.
