Abstract:
1. A two-element array antenna system, comprising: only a first antenna element and a second antenna element; a transmitting, receiving, and processing (TRP) system coupled to the first and second antenna elements, the TRP system being coupled to the first antenna element via a single first transmission element, the TRP system being coupled to the second antenna element via a single second transmission element, the first and second transmission elements having respective transmit-path and receive-path functionality; and a first circuit comprising a sampling element, the sampling element comprising one or more directional couplers electromagnetically coupled to the first transmission element and the second transmission element, the sampling element being configured to sample a first transmit signal from the first antenna element and a second transmit signal from the second antenna element, the first circuit further being configured to generate a first output signal based at least in part on the first transmit signal and the second transmit signal, wherein the TRP system is configured to:
