Paper Abstract

Circuits in which oscillators are integrated with antennas to form quasi-optical sources have applications in phased array radar (1), quasi-optical local oscillators (2), and a variety of obstruction detection and process control applications (3). In this paper we describe a low-cost planar oscillator circuit in which 2 FETs are coupled by microstrip rampart line antennas and operate in a push-pull power combining configuration. Prototype circuits have been constructed which operate at X-band; the same principle may be applied at higher frequencies.
