Abstract
A receiver includes a phased array antenna and a demodulator. The phased array antenna includes first and second antenna elements and a phase shifter for shifting the phase of a signal received by the first antenna element by a predetermined amount. The demodulator includes a first junction circuit which receives a local signal and a signal output from the phase shifter and which generates a plurality of signals having a phase difference; a second junction circuit which receives a local signal and a signal output from the second antenna element and which generates a plurality of signals having a phase difference; signal combiners for combining corresponding signals output from the two junction circuits; power detectors for detecting the signal levels of the output signals of the signal combiners; and a converter for converting the outputs signals of the power detectors so as to obtain IQ signals.
