Abstract
A two-element array antenna system includes a first antenna element and a second antenna element. The first and second antenna elements respectively include first and second frequency multipliers. 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 TRP system is configured to transmit to the first antenna element a first input signal at a sub-multiple of a first frequency, receive from the first frequency multiplier a first calibration signal based on the first input signal, transmit to the second antenna element a second input signal at a sub-multiple of the first frequency, receive from the second frequency multiplier a second calibration signal based on the second input signal, and determine, based on the calibration signals, a relative phase difference between the first and second transmission elements.
