Abstract
A system is disclosed and includes a plurality of antennas. Each antenna includes a plurality of conductive elements and is circularly polarized. The plurality of conductive elements is configured to receive radio frequency (RF) signals. A first end of each of the plurality of conductive elements is electrically coupled to a printed circuit board, which includes a plurality of coupler circuits and a switching circuit. The plurality of coupler circuits is configured to combine the RF signals and output a signal to the switching circuit based on the combined RF signals. The switching circuit is configured to selectively output one of the signals based on at least one control port of the switching circuit being selectively activated by a control signal. The system also includes a microcontroller configured to determine, based on at least one of the signals, an angle of arrival associated with the plurality of antennas.
