Abstract

A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with quad notched bands using quad-mode stepped impedance resonator (QMSIR) is investigated in this paper. The resonance properties of the QMSIR are studied. Then, quad notched bands inside the UWB passband are implemented by coupling the proposed QMSIR to the main transmission line of a basic microstrip UWB BPF. The quad notched bands can be easily generated and set at any desired frequencies by varying the design parameters of QMSIR. For verification, a new microstrip UWB BPF with quad notched bands respectively centered at frequencies of 5.2 GHz, 5.8 GHz, 6.8 GHz and 8.0 GHz is designed and fabricated. Both simulated and experimental results are provided with good agreement.
