The research of a new type aperture-coupled microstrip antenna

A new type dual-frequency dual-polarization aperture-coupled microstrip antenna is described in this paper. This antenna has broadband performance, that can get to 240 MHz when VSWR is less than 2.0 in 1.3 GHz and 200 MHz when VSWR is less than 1.5 in 700 MHz. The isolation between these two antennas is less than -45 dB, the structure of this antenna is compact, simple and easy to fabricate.
