Abstract :
The filtering performance of polarization sensitive array is investigated theoretically, consisting of N pairs of crossed dipoles. The desired signal and interference are completely polarized and from random directions. The outputting signal to interference plus noise ratio (SINR) is mainly related with the spatial matching coefficient and polarizational matching coefficient between desired signal and interference. To gain the low SINR, the interference must come from the same direction and with the same polarization with the desired signal
