Electrically small, super directive antennas
First Claim
1. A receiver system comprising:
- a plurality of antennas comprisinga first antenna configured to receive a first signal; and
a second antenna configured to receive a second signal; and
a signal processing circuit comprising a phase shifter configured to apply a phase shift to the received second signal, wherein the phase shift applied by the phase shifter is a function of an angle of incidence of the second signal measured relative to a boresight direction of the plurality of antennas,wherein the signal processing circuit is configured to form an output signal that includes the phase shifted second signal.

Abstract
An electrically small receiver system is provided. The receiver system includes a plurality of antennas and a signal processing circuit. The plurality of antennas includes a first antenna configured to receive a first signal and a second antenna configured to receive a second signal. The signal processing circuit includes a phase shifter configured to apply a phase shift to the received second signal. The phase shift applied by the phase shifter is a function of an angle of incidence of the second signal measured relative to a boresight direction of the plurality of antennas. The signal processing circuit is configured to form an output signal that is a combination of the received first signal and the phase shifted second signal.
