Abstract
This paper shows variations on bandwidth for the 5-microstrip 4-port structure by cutting out part of 2nd and 4th line of 5 lines. In 2nd line case, the bandwidth to pass is decreased by 300MHz and one of two input ports operates in diplexer. Both of 2nd and 4th line cut takes each of two input ports as a diplexer. The bandwidth for 4th line case has almost same bandwidth for the unmodified structure, a bit wider than that of the 2nd line case. Especially the isolation between input and other out port in center frequency of stop band shows 41dB for port 1, 32dB for port 2.
