Abstract :
A Band pass filter which operates in the ultra wide band (UWB) range is designed and implemented. The proposed filter consists of two Interdigital coupled lines at the terminal end and three circular shaped electromagnetic band gap structures (EBG) at the centre of filter configuration. The Circular shaped EBG structures act as a multimode resonator (MMR) which is used to tune the frequency ranges of filters as well as to improve the return loss characteristics of filters. The bandwidth of proposed filter is 11.88 GHz (3.68-15.56 GHz) which covers the entire UWB range.
