Abstract :
An active microstrip patch antenna for quasioptical power-combining arrays is described. The oscillator circuit uses two Gunn diodes which symmetrically load a resonant patch. The symmetry of the structure and the push-pull operation of the devices results in a dramatic decrease in H-plane cross-polarisation, improved copolarisation patterns, and twice as much power as a single-device patch.
