摘要
本文基于理论计算与CST软件仿真和优化,根据卫星通信的需要,设计了一种高带外抑制的Ka卫星通信滤波器。通过加入脊块产生电容,从而可以形成谐振腔。该滤波器具有工作带宽宽,寄生通带比较远的特点,可以满足卫星通信的需要。
Based on theoretical calculation and CST simulation,a Ka band-pass filter with High restraint in Band-stop is designed for the purpose of satellite communication. Resonators are formed by introducing appropriate capacitive posts at sui table intervals along the waveguide. We can realize high restraint in band-stop by move the first post and last post into the input and output coupling waveguide,which can reach the requirements of satellite communication.
