Abstract :
In this paper, an iris waveguide filter with substrate integrated waveguide (SIW) structure at satellite communication band is discussed. The SIW structure is realized by via-holes on the substrate and shows a possibility of integration with other circuits. The iris waveguide filter has the insertion loss of 3.36 dB, the return loss of about 20 dB, and bandwidth of 3 %. Also, the iris waveguide filter using SIW has a sharp skirt characteristic.
