Abstract:

A Ku-band waveguide duplexer together with the theory of the metal-septum filter is introduced.First,it is divided into two parts for theoretical analysis,the septum part and waveguide resonator part.Then HFSS software is used to optimize it.Finally,the consistence of the measurement obtained from the processed and assembled duplexer with the simulation result indicates that this duplexer has such features as high Q factor and interport isolation,small size,and etc.

Key words: metal septum;waveguide duplexer;HFSS
