In this paper, a fourth order bandpass Chebyshev filter based on Iris discontinuities and using SIW technology is designed. The structure of the filter consists of SIW cavity resonators that are connected to each other with Iris discontinuities, which operate as impedance inverters. This filter is implemented on a substrate of RO4003C with a central frequency of 2.45GHz and a fractional bandwidth of %4.08 and is designed to be used in Wireless Local Area Networks (WLAN) or Bluetooth. The main idea is to reduce the size of the filter with a factor of two without any distortion in the frequency response. Simulations are done using full-wave HFSS simulator.
