Abstract

The main objective of the paper is to portray the design of microwave bandpass filter with the help of micro strip design. The proposed design of filter is simulated, fabricated, measured and analyzed for lumped and discrete element UWB filters. The range of this filter is about 3.1 GHz to 10.6 GHz. The filter is also expected towards producing low insertion loss. Proposed filter is simulated by HFSS and result show reasonable performances over entire UWB. Averaged insertion loss for UWB of this filter is about 0.2 dB within entire band with constant group delay. The equivalent circuit model of the UWB bandpass structure is presented in this paper. The results of UWB bandpass filter are compared with the general bandpass filter results which show that the UWB filter is fairly good.
