Abstract: This paper presents design, simulation, fabrication and electrical analysis of a triple notched band UWB band pass filter. Short circuit stubs and microstrip line defected structures are used to design a triple notched band UWB filter. The proposed UWB BPF consists of five short circuited stubs of quarter wavelength attached to the feed line. The notched bands are created by introducing three U-shaped defected microstrip structures in the feed line. The proposed structure of the filter is designed, simulated on CST MSW and fabricated using conventional photolithography process. This band pass filter is designed to pass the UWB signals between 3.1 GHz to 10.6 GHz and to eliminate INSAT signal (4.6 GHz), WLAN signal (5.6 GHz) and satellite communication signal (8.0 GHz). The experimental results of this fabricated filter are compared with the simulated results and they are found to be in close agreement to each other. The Electrical equivalent circuit of this triple notched band filter is also presented in this paper and verified mathematically. This filter is compact in size and better in performance. It can be incorporated in UWB communication system to efficiently increase the interference protection from undesired signals. The physical dimension of this filter is about 30x10.5 mm2.Abstract: This paper presents design, simulation, fabrication and electrical analysis of a triple notched band UWB band pass filter.
