2.45GHz dual polarized aperture-coupled antennas with high isolation performance

A new design of dual polarized antennas is presented. The antennas feature high isolation of -33.8 dB, and half power beamwidth of 88 degrees, and compact size. The two antennas are fed by aperture coupled feeding technique, and two identical feedline substrates are used. The two proposed antennas could be used as elements in a compact dual-polarized array. The measured results are in good agreement with simulated ones.
