Full-duplex transceiver

Abstract

A full-duplex transceiver includes a dual-polarized antenna, a dual-mode waveguide circulator, and at least a receiver port and a transmitter port. The dual-polarized antenna is configured to transmit first electromagnetic waves polarized by the dual-polarized antenna according to a first polarization, and receive second electromagnetic waves polarized according to a second polarization orthogonal to the first polarization. In response to electromagnetic waves being received at the transmitter port, the waveguide circulator guides a TE10 mode of the electromagnetic waves to the antenna for coupling the TE10 mode of the electromagnetic waves to the antenna and polarizing the electromagnetic waves according to the first polarization to form the first electromagnetic waves. In response to the second electromagnetic waves being received at the antenna, the waveguide circulator couples a TE20 mode of the second electromagnetic waves and guides the TE20 mode of the second electromagnetic waves to the receiver port.
