Abstract
An apparatus and method for enhancing full-duplex radio communications using an indented transmitter and receiver antenna. A multi-element antenna array is configured with each antenna coupled to a circulator that has connections to both a transmission path and a receiving path. The apparatus is configured with indentations that provide a tilting of the array from its broadside to create a progressive phase delay between adjacent pairs of elements. Transmitted and received waves travel a single trip through the indention, while antenna reflection or circulator leakage travels a round trip through indention, so that these signal components can be readily separated to achieve high levels of isolation during full-duplex transmitting and receiving.
