Design of a FSS filter with shorting stubs for compact E-plane duplexer application

A FSS filter with shorting stubs will be designed in this paper. This filter provides compact design and sharp frequency selectivity by using transmission-zeros, and it is designed for a compact E-plane duplexer. It can be fabricated in a simple and economical way. We simulate the filter with CAD tool, and the tested results show good agreement with the design target.
