摘要

本文介绍了一种全封装的宽上阻带双模带通滤波器(BPF)。采用短板负载的带状贴片谐振器实现TM00模式和TM01模式下的双模带通性能。为了消除带状线贴片谐振器的其他谐波，首先提出了一种共模双点插入馈电技术，以防止高阶模的激发。为了验证设计理念，采用多层液晶聚合物(LCP)电路技术设计并制作了工作在4.0 GHz、分数带宽(FBW)为8.2%的封装双模BPF原型。最后的理论验证和实验验证了该方法的宽阻带抑制值高达4.3f_{0}$，很好地验证了馈电方法。

A Fully Packaged Bandpass Filter on Stripline Patch Resonator With Wide Upper Stopband

In this letter, a fully packaged dual-mode bandpass filter (BPF) with wide upper stopband is presented. The stripline patch resonator loaded by the shorting slabs is adopted to achieve the dual-mode bandpass performance under operation of TM00 mode and TM01 mode. To remove other harmonic resonances of the stripline patch resonator, a common-mode double-point inset-feeding technique is proposed at the very beginning to prevent the excitation of high-order modes. To verify the design concept, a prototype packaged dual-mode BPF working at 4.0 GHz with the fractional bandwidth (FBW) of 8.2% is designed and fabricated using the multilayer liquid crystal polymer (LCP) circuit technology. Final results theoretically demonstrate and experimentally confirm that a wide stopband rejection up to $4.3f_{0}$ is obtained, well verifying the feeding method.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
