Abstract
A polarization reconfigurable antenna used in polarimetric radar was studied in this paper. The millimeter microstrip polarization reconfigurable antenna is based on multi-polarized subarrays which has relatively simple feed system. The polarization of far field electric field can be reconfigured by amplitudes and phases of the feeds. Far field electric field with P subarrays based on rectangular patch was first analyzed. Then the simulation results of the polarization reconfigurable antenna with four subarrays were presented. The measuring results were shown finally. The cross polarization in 4 degree beam width is less than -15 dB.
