Abstract

A dual-linearly polarized microstrip antenna array working in the frequency of 2.4GHz is proposed according to the requirements of retrodirective antenna system. As the simulated results shown, both of the cross-polarization levels of the horizontal port and vertical port are lower than -20dB. Both of the horizontal-polarized and vertical-polarized main beams can scan from the angle -45^o to +45^o. The antenna array meets the requirements of retrodirective antenna system and can be used in other duplex communications.
