Abstract
Transmission line characteristics in microstrip line is used to in this paper. 5-microstrip lines composed of various spacing between them suggests characteristics of a diplexer in simulation. By applying the simiulation results, the diplexer realized shows better results of flat responses in bandpass characteristics and bandstop characteristics around 15 dB than symmetric spacing one.
