Voltage Controlled Self-Oscillating Microstrip Patch Antenna
An active rectangular microstrip patch antenna for quasi-optical power combining arrays is hereby described. Part of the patch metallization was removed to form a rectangular opening where a Gunn diode was placed. This modification lowered the Q and allowed the oscillating patch to perform VCO capabilities. Patch parameters were optimized using a moment method procedure. A tuning range of more than 300 MHz at 9.85 GHz and EIRP of 208 mW was obtained. A clear spectrum with no spurious components of the free running oscillating antenna was observed. Injection locking experiments were performed. At 9 V bias, a locking gain of 40.9 dB with locking bandwidth of 5.9 MHz was obtained. Radiation patterns in E and H plane were measured. Low levels of cross-polarisation were observed.
