抄録

A polarization switchable active integrated array antenna is proposed in this letter. The proposed antenna accommodates two microwave circuits; an oscillator and PSK modulator with antennas for both vertical and horizontal polarizations. Employing a PSK modulator in the horizontal feed line, it is possible to flip the horizontal polarization of the antenna and hence the polarization can be switched between ±45°. The basic concept of the proposed antenna is experimentally confirmed by using a 10-GHz band prototype antenna and better than 15-dB cross-polarization suppression is obtained.
