A novel compact and highly selective Ultra Wide Band (UWB) filter is proposed using multimode resonator (MMR) technology.

Furthermore, dual-notch band characteristics are realized at 6.80 GHz and 9.82 GHz, employing asymmetric coupled lines and the split ring resonator (SRR) methods. Eventually, by using a Defected Ground Structure (DGS), the filter’s correct transmission zero is deepened, further enhancing the out-of-band suppression performance
