Abstract
In this paper, a resonator with the substrate integrated waveguide(SIW) structure at the satellite communication band is presented. The SIW structure is realized by via-holes on the dielectric substrate and has an advantage of integration with other circuits. For the measurement, a designed back-to-back transition has the insertion loss of 0.4 dB at 18 GHz. Also, the quality factor of the resonator with the SIW structure including back-to-back transition is obtained to be 222. The high-Q resonator with the SIW structure can be used in filter, oscillator, and voltage controlled oscillator.
