Abstract :
A full-duplex frequency-controlled phased array is demonstrated. Scanning is achieved through the use of a single VCO without any change in the radiated frequency. A compact, novel feed network is designed to distribute the VCO signal to a set of heterodyne mixers. Patterns in both transmit and receive mode demonstrate 40deg of scanning
