Abstract

In this article, design and electrical analysis of UWB filter with a notch band is presented. Initially basic UWB filter is designed by using parallel coupled microstrip line with rectangular shaped defective ground plane. Then, to achieve band notch characteristics to eliminate satellite signal at 6.25 GHz, a quarter wavelength open circuit stub is connected with feed line of basic filter. To validate the design theory, a microstrip line UWB BPF with single notch band is designed, and fabricated. The electrical analysis of this filter is also proposed in this paper. The comparison among the results, in the simulated frequency response, measured VNA results and electrical model response shows close agreement. This filter compact in size approximately (17 mm × 8.5 mm). The filter is design by using microwave substrate GML 1000 of dielectric constant 3.2 of height 30 mil. This filter may be useful for microwave communication system.
