Abstract
A tire pressure monitoring system (12) for an automotive vehicle (10) has a receiver circuit (28). The vehicle (12) has a plurality of wheels (14A-14D). A plurality of antennas (31A-31D) are adjacent to one of the wheels (14A-14D). The plurality of antennas receive RF signals from a pressure sensor (16A). An adder circuit (30) is coupled to the receiver circuit and the plurality of antennas. The adder circuit receives the RF signals and adds them together to form a sum signal. The sum signal is coupled to the receiver circuit.
