Abstract

In this letter, a rotationally-symmetrical array (RSA) arrangement of a receiving dipole array antenna is optimized to maximize the performance of the null-beamforming method for the suppression of self-interference. The optimum RSA for a receiving dipole array with four elements is clarified. Through numerical simulations, we found that the optimized RSA arrangement suppressed the self-interference significantly.
