In this paper a compact Ultra Wide Band filter with notch at WLAN frequency is designed. The filter is a designed using coupled lines arranged in inter digital capacitor form. The filter is designed to allow microwave signals in the range of 2GHz to 7GHz with a notch at 5GHz. The measured results show the notch at 5GHz with transmission coefficient of-14dB. With uniform group delay in pass band and nonlinear group delay at notch frequency. © 2019 The Authors. published by EDP Sciences.
