Abstract

A transceiver for providing full-duplex communications includes a multilevel patch antenna array having a first patch antenna array for transmitting the first carrier signal on the first channel including a first plurality of patch antennas thereon and a second patch antenna array for receiving the second carrier signal on the second channel including a second plurality of patch antennas thereon. Transmitter circuitry associated with the first patch antenna array transmits first signals having a first orthogonal function applied thereto on a first channel on a first frequency band. Receiver circuitry associated with the second patch antenna array receives remotely transmitted second signals on a second channel on the first frequency band having a second orthogonal function applied thereto and the first signals transmitted from the first patch antenna array having the first orthogonal function applied thereto on the first channel on the first frequency band at a same time on the first frequency band. The receiver circuitry only processes received signals including the second orthogonal function. The first orthogonal function applied to the first signals transmitted from the first antenna array and the second orthogonal function applied to the second signals prevents interference between the first signals and the second signals that are being simultaneously transmitted and received on the first frequency band at the multilevel patch antenna array.
