An Ultra wide Band pass filter which operates from 3.45-10.35 GHz is designed and presented. The proposed filter consists of short circuited shunt stubs and circular shaped defected ground structures (CDGS). The CDGS acts as a low pass filter which rejects higher order frequencies whereas the short circuited shunt stubs act as a high pass filter. CDGS also suppresses the harmonic and improves the frequency response characteristics of the filter. © 2014 IEEE.

In this paper, an approach is taken to reduce the size and suppress harmonics of rat race coupler with the help of Circular defected ground structure. The reduction in size is possible due to the lowering of resonant frequency which in turn is a result of slow wave effect. The proposed structure is additionally able to make the response as a wide band. The two parameters of CDGS are modeled rigorously to obtain the achieved response. First, the conventional rat race coupler is studied and later the effect of CDGS on the same structure is analyzed. © 2016 IEEE.
