Abstract
A triple pass band filter is proposed for wireless applications. Four cross coupled Stepped Impedance Resonators are used for the purpose. Three pass bands at 2.4, 3.5 and 5.4 GHz are achieved. Minimum Insertion Loss of the three pass bands are 1.00, -0.52 and -0.92 dB respectively. The Return Loss in the said pass bands are -27,-21 and -22 dB. The overall size of the designed filter is 24.7 mm x 18 mm (0.19 $\lambda_{g}$ x 0.14 $\lambda_{g}$). The Defective Ground Surface is introduced in the design to reduce the spurious pass bands and hence to improve the pass band selectivity and stop band suppressions.
提出了一种用于无线应用的三通带滤波器。四个交叉耦合阶跃阻抗谐振器用于此目的。实现了2.4、3.5和5.4 GHz三个通带。三个通带的最小插入损耗分别为1.00、-0.52和-0.92 dB。所述通带的回波损耗为-27、-21和-22 dB。所设计滤波器的整体尺寸为24.7 mm × 18 mm (0.19 $\lambda_{g}$ x 0.14 $\lambda_{g}$)。在设计中引入缺陷地面以减少杂散通带，从而提高通带选择性和阻带抑制。
