Abstract
A low profile broadband dual polarized patch 1×4 sub-array in a 1-D infinite array is presented. It uses double differential L-probe coupled feeding technique to reduce cross-polarization levels and to enhance impedance bandwidth. The total size of proposed sub-array is 143×612.5×26mm3. The simulated results indicate a 14-dB impedance bandwidth of 300MHz (1.1–1.4GHz) for both polarizations. The isolation is better than 51dB. The realized gains are from 11dB to 13dB. The gain difference between the two polarizations is less than 0.25dB. The relative cross polarization levels are −37dB within the HPBW range for H-pol, and −40dB within ±30°for V-pol.
