Design of a waveguide bandpass filter with inductive irises for a satellite application
Laboratory of science and advanced technologies, Abdelmalek Essaadi University, Tetouan, Morocco
This paper presents a synthesis, design, and simulation of a bandpass rectangular waveguide filter with symmetrical transverse discontinuities operating in the X-band (WR90) with a central frequency of 11GHz, a fractional bandwidth of 3.1%, an undulation ripple of 0.014 dB inside the bandwidth, and a return loss level around 15 dB. The simulation is effectuated under the HFSS environment, where the results of the S-parameters in dB and degree were verified using a CST environment. The obtained results had proven the validity of the conception of our structure since it has shown a symmetrical aspect around the central frequency in both 3D simulators after optimizing the overall dimensions of the irises, also our study has proved that irises are a reliable way to design bandpass filters especially, where their dimensions mainly affect the filter response in terms of the return loss quantity, the insertion loss, and the filter’s bandwidth.
