  • Patent number: 6131022
    Abstract: In one aspect of the present invention, a transceiver includes a pair of antennas with one of the receive channels including a predetermined phase shifter for shifting one of the received signals prior to combining the received electromagnetic energy to form a combined signal for processing by a receiver. The amount of phase shift may be set to maximize the combined signal. The transceiver accounts for signal fading resulting from multiple path reflection, and is especially beneficial in a hand-held or mobile unit. In another aspect, an antenna system includes a pair of elongated quadrifilar antennas, which may be disposed so as to have their longitudinal axes parallel or coincidental as desired. A method for maximizing receipt of electromagnetic energy is also described along with a detector useful for determining the presence of information associated with electromagnetic energy.
