A Narrow-Band Iris Band-Pass Filter for Radar Applications
摘要
In this paper, an iris band-pass filter (BPF) is designed with centre frequency of 97.75 GHz and the fractional bandwidth (FBW) is 4.6%. The design and simulations are carried out using Finite Element Method (FEM)-based Ansys High-Frequency Structure Simulator (HFSS). The proposed iris filter is having pass band ripple of 0.1 dB and return loss < − 15 dB throughout the operating frequency. The design procedure and simulation results for millimetre waveguide BPF are presented in this work.
