Antenna pair with self-interference cancellation for full duplex communication
A self-interference cancellation (SIC) antenna pair for full duplex communication is proposed. It consists of two aperture-coupled patch antennas with orthogonal linear polarizations and an auxiliary port loaded with a proper reflective termination. The auxiliary port introduces an indirect coupling path and the coupling signal is reflected to RX port and superposed with the direct coupling to make a cancellation. As a result, the isolation between two antennas is improved from 25dB to more than 40dB over the entire working band of 2.35–2.55GHz, while, it has little influence on return losses and radiation patterns of the two antennas. The performances indicate the proposed antenna pair a good candidate for full duplex communication applications.
