| 摘 要： | 本文应用传输线理论对PBG结构带通滤波器进行分析,并在此基础上仿真、设计一种新颖的K波段的双模带通滤波器.光子带隙结构具有独特的带阻特性,对高次模具有很好的抑制特性,能够提高微波电路系统的抗干扰能力.由于PBG的慢波特性,使得带通滤波器的结构尺寸大为减小,符合系统小型化的要求.在此基础上,就这种结构应用Ensemble软件进行优化仿真.最后制作出滤波器并进行了测试.仿真结果与实验结果吻合很好,插入损耗为-4.5dB,通带中心频率为25.2GHz,-3dB带宽为1.8GHz,相对带宽7%.

| Abstract: | Band pass filters of PBG(photonic band-gap) structures were analyzed based on the transmission line theory in this paper,and a novel K band dual-mode band-pass filter was designed and simulated by using this theoretical analysis.Due to their unique stop bands characteristics and slow-wave effects,PBG structures exhibit good suppression of high order harmonics and reduce geometrical size of circuits system to meet the requirement of miniaturization.A good agreement between the experiment and simulation(with Ansoft's Ensemble software) results had been achieved.The center pass-band frequency of this filter is 25.2 GHz,and insertion loss is less than -4.5dB.Its-3dB band width is 1.8GHz about 7% of center frequency. |
