基于SIR和UIR的双通带带通滤波器的设计
Design of a Dual-band Bandpass Filter Based on the SIR and UIR
摘要
Abstract
A dual-band bandpass filter is proposed based on X/2 stepped-impedance resonators (SIRs) and u-niform impedance resonators (UIRs)introduced,and the equivalent circuit of the proposed filter is given. By adjusting the impedance ratio and length of SIR and UIR,the proposed filter operates at the expected two frequencies. The structure becomes more compact by folded the SIR and UIR. A basic agreement of the simulated and measured results shows that this proposed filter operates at 2. 4GHz and 5. 59 GHz with its insertion losses of 1. 69 dB and 4. 33 dB respectively. The presented filter has several characters such as small size,simple structure and easily designed and realized,and it suqqested that do could be widely used in the radio frequency (RF) front-ends.关键词
