Abstract :
An active integrated antenna array consisting of a parallel feedback FET oscillator and a patch antenna is demonstrated. In this paper a two element array was fabricated and examined. The patch antenna was incorporated into oscillator feedback loop to enhance stability of the resonator operation frequency. Two slot apertures were embedded in the ground plane of the patch resonator and electromagnetically coupled with microstrip feed lines which consist of the oscillator feedback loop. An observed spectrum and an antenna pattern were also investigated
