In this paper, A new miniaturized Dual-mode, Dual-Passband filter using modified multi-mode resonator and coupled feed lines is proposed. In the proposed structure, coupled feed line is used not only to feed MMR, but also to generate stopband between two passband. Later, widening of this stopband is achieved as a result from loose coupling of feed lines and(More)
This paper suggests a novel design of an ultra-wide band - Band pass filter (UWB-BPF) with and without via hole. The filter consists of identically paired Centrally Loaded Resonator (CLR) and Inter-digital coupled lines. Inter-digital coupling structure is employed to feed resonator part as well as to generate transmission zeros at the edge of passband with(More)
An UWB-BPF is proposed using a new type of concentric ring defected ground structure (DGS), aiming at transmitting the signals in the whole UWB passband of 3.1GHz to 10.6GHz. In the Design DGS is used to realize high impedance microstrip lines, which make the edge of passband frequency range convenient. DGS structure looks as two concentric rings placed(More)
