Abstract

A two-element array antenna system includes a first antenna element and a second antenna element. A transmitting, receiving, and processing (TRP) system is coupled to the first and second antenna elements via, respectively, a single first transmission element and a single second transmission element. The first and second transmission elements have respective transmit-path and receive-path functionality. The TRP system is configured to determine an amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, and, based on data obtained during the determination of amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, determine an amplitude offset and phase offset associated with the receive-path functionality of the first and second transmission elements.
