| 摘 要： | 利用基片集成波导的高通传输特性以及蝶型光子带隙结构的阻带特性,构建了一种新型结构的基片集成波导带通滤波器.为了验证该想法,设计了1个中心频率为4.65GHz,分数带宽为40%的滤波器,电磁仿真结果表明该滤波器在频率为3.71～5.6GHz范围内具有明显的通带特性,带内最大插入损耗约为0.4dB.利用PCB工艺制作了该滤波器的实物,使用矢量网络分析仪对其进行了测试,测试结果表明该滤波器的通带为3.78～5.76GHz,分数带宽约为41%,带内最小插入损耗为0.72dB,最大插入损耗为1.65dB.电磁仿真结果和实际测试结果较一致。

| Abstract: | A novel broadband substrate integrated waveguide bandpass filter was presented based on the highpass characteristics of substrate integrated waveguide(SIW) and the bandstop performance of butterfly radial slot photonic band gap(PBG) structure.In order to verify this idea,a wideband bandpass filter with 4.65 GHz center frequency and 40% fractional bandwidth was designed.The electromagnetic simulation results show good passband characteristics from 3.71 to 5.6 GHz,while the maximun insertion loss is about 0.4... |
