Abstract: In this paper, a sharp rejecting ultra wide bandstop filter (BSF) design is demonstrated. To get sharp rejection at pass bands a model is considered with three zero levels in transmissions by implementing this we can achieve stop band characteristics also. Bandwidth of the stop band and depth of the stop band can be varied and controlled by the Impedances of configuration used in the design. In order to derive design equations here we have used a simple model of a lossless transmission line. Further, for convenient folding of the design low impedance sections were replaced by its compact geometry. To support the theoretical values, a band stop filter which is having a sharp rejection at 10dB with a rejection bandwidth of 44% ranging from 0.77GHz to 1.1GHz has been designed and fabricated.
