Design of Ka-Band Planar Pass-band Filter of Fifth Order Based on SIW Technology

Abstract

This paper proposes a fifth order wide band pass filter, based on the technology of Substrate Integrated Waveguide SIW, endowed by inductive iris and manufactured by using the substrate Polyflon Cuflon (tm), that made him extra planar component with low loss. Where the ideal return loss “RL” reaches almost -40dB at the frequency 32.54 GHz. This filter has been designed in order to resonate in the millimeter waves, especially Ka band, with wide band BW of 7GHz. This design has been developed and simulated using EM software “HFSS”.
