Abstract :
A compact unit of parallel coupled transmission line is presented for design of a compact, sharp-rejection, wideband bandstop filter (BSF). The rejection depth and bandwidth can be easily controlled by the coupled-line parameters. A lossless transmission line model is used for filter analysis. Design equations and graphs are presented in order to facilitate the design procedure. Theoretical prediction is verified in microstrip line by fabricating a prototype single section coupled-line BSF.
