Abstract :
In this paper, a novel ultra-wideband(UWB) bandpass filter using inductance-loaded Y-shaped multiple-mode resonator (MMR) is presented. To get the desired passband (3.1-10.6GHz), the resonant characteristics of the proposed structure are investigated. Two identical aperture-backed parallel-coupled microstrip lines at the two sides have been used to get tight coupling. Both the simulated and measured results show that the proposed UWB filter has a greater than 12-dB return loss from 3.1-10.6GHz and a upper stopband with more than 20-dB attenuation up to 15.8GHz. In addition, the size of this proposed filter is greatly minimized compared with the conventional ones.
