Abstract

A compact FSS (frequency selective surface) filter will be designed in this paper. The length of the filter is reduced by the use of both bandpass and bandstop FSSs. A sample filter at 8.05 GHz will be designed using CST Studio as an example. Simulation results show that the FSS filter has a bandwidth of 800 MHz and a reflection lower than -20 dB. Tested results from this sample filter agree well with the simulation results. The length of the sample filter is less than half of a directly-coupled waveguide filter with the same specifications.
