Simulation design of S band harmonic filter with wide-band waffle-iron

It is composed of two wave-guide waffle-iron harmonic filters. HFSS proves that designed filter with the voltage standing wave ratio and the insertion loss band is low, the design makes the power-handling capacity of filter is high and the filter reliability is well, the filter can be applied to various reconnaissance equipments with harmonic. It isn't only controlling secondary and thrice harmonic but also controlling fourth harmonic, especially it can cut down 80 dB fourth harmonic.
