| 摘 要： | 提出了一个CPW/微带复合谐振腔结构组成的双通微带滤波器设计方案.该滤波器由1个开路加载的1/4波长CPW复合谐振腔和2个短路加载的1/4波长的CPW复合谐振腔组成.该滤波器利用不连续失配理论产生了可调节刻痕阻带,采用加载短接线模拟低通滤波器改善了阻带特性.实测数据表明,滤波器在3.4～9.1 GHz（-3 dB带宽）范围内具有通阻带特性,相对带宽大于92%,带外衰减优于-30 dB,刻痕阻带的调节范围为5.5～8 GHz,与仿真结论基本一致.

| Abstract: | This paper presents a design scheme of bi-pass microstrip filter which is composed of a coplanar waveguide(CPW) / hybrid microstrip resonator chamber.The proposed filter is composed of a 1/4 wavelength CPW open-end hybrid resonator and two 1/4 wavelength CPW short-circuited hybrid resonators.The discontinuous mismatch of the two resonators is used to get the adjustable notch band and it also exhibits good out-of-band performance by the adoption of a short stub-loaded resonator.Experimental results demonstra... |
