An X-band experimental model of a millimeter-wave interinjection-locked phased array system

An interinjection-locked 10 GHz model of a millimeter-wave phased-array system has been built and tested. It has been successfully demonstrated that this novel technique can be used to control limited-scan phased-array antennas. A beam shift of +or-5 degrees has been achieved with only one phase shifter in a four-oscillator system. Adaptability to monolithic fabrication and a reduction in the number of phase shifters required make this method attractive for use at millimeter-wave frequencies.<
