This paper presents a compact microstrip three-pole diplexer whose multiband performances is created by using two composite right/left handed (CRLH) filters having a common input splitter. The two passband channels have high isolation between them which is critical in order to prevent undesired interaction which would otherwise adversely affect the diplexer’s passband response. Analysis of the diplexer using circuit models was verified via ADSTM (MoM).
