Abstract :
The authors describe a novel active radiating module in which an FET source is integrated with a multilayer slot coupled patch antenna. A design procedure is given and the performance of an X-band prototype circuit is described. Prototype circuits showed 4.81-mW power output and 50-MHz tuning range at 4.893 GHz. The initial results suggest that this device has potential for use in low-cost transmitters, active arrays, spatial power combiners and quasi-optical combiners.<>
