This paper quantitatively investigates the inherent self-interference (SI) suppression property of dual-polarized fullduplex (FD) linear phased array antennas. The amount of systemic SI suppression is derived for an N×1 array as a function of the phase taper applied on it. The systemic SI suppression occurs due to the destructive interference of signals in different phased array channels. Results indicate more than 10-15 dB SI suppression for most beam directions, and around 2 dB SI suppression for the normal beam direction.
