Abstract :
A new design of a wideband dually-polarized shorted microstrip patch antenna coupled to hook shaped probes is presented. The antenna is designed to operate around 4 GHz. The mechanisms of the shorted microstrip patch antenna provide wider impedance bandwidth over 37%. The shorted patch is smaller than the full unshorted patch. A gain around a 9-10 dBi is achieved within the bandwidth. The present design provides about 40 dB isolation level between the two ports. A stable low cross polarization level of -20 dB is obtained.
