Abstract :
A novel H-shaped oscillating patch antenna is proposed. In this approach, the H-shaped antenna can serve as a filter, an output matching circuit, and a harmonic tuner in addition to being a load and a radiating element. A prototype is designed, fabricated and tested at 3.65 GHz. Measurement results reveal a 41 dB rejection in the second harmonic radiation. Compared to the one using a rectangular patch, our design shows a size reduction of up to 30%. This active antenna is shown to be a good candidate as an element for a highly compact oscillating array for power combining and radar applications.
