Abstract

Based on substrate integrated waveguide (SIW) technology, a reflection attenuator applied in Ku band is proposed here. The attenuator is composed of three SIWs and two SIW micro-strip converters using the FR4 substrate. The whole size of the attenuator is 31×8.0×1.6 mm, which is compact and easy to be integrated, meeting the requirements for miniaturizing the high-power microwave test instrument. The attenuation value of the attenuator was calculated using the transmission matrix and the equivalence relation between SIW and rectangle waveguide. Also the attenuator was simulated by high frequency structure simulator (HFSS) software and fabricated. The measurement results are fit well with the ones by calculation and simulation..
