Abstract :
This paper presents a novel electronically tunable substrate integrated waveguide (SIW) cavity resonator at microwave frequency. The resonant frequency of the cavity is tuned with different DC biasing voltages applied over a varactor coupled to the cavity. This structure has been analyzed with a full-wave software package. To validate our analysis, an X-band reflective tunable SIW cavity resonator is designed and fabricated as an experimental example. Measured results show that the tuning range of the resonator is about 160 MHz with loaded QL of 150. The proposed resonator can be used to design tunable devices such as microwave and millimeter-wave voltage controlled oscillator (VCO).
