Abstract

A self-steering antenna apparatus for receiving and transmitting electromagnetic signals, includes a plurality of antennas for receiving and emitting electromagnetic signals and a plurality of receivers for processing the received electromagnetic signals. Each one of the plurality of receivers corresponds to a respective one of the plurality of antennas. Each receiver provides signal strength information indicating a signal strength of the electromagnetic signal received by the corresponding antenna. A comparator compares the signal strength information provided by each receiver, and determines which of the antennas is receiving the strongest electromagnetic signal. Switching circuitry switches the received electromagnetic signals and the signals to be emitted, based on the comparison performed by the comparator, the switching circuitry selecting one of the plurality of antennas to emit and receive the electromagnetic signals based on the comparison.
