摘要

提出了一种在多层液晶聚合物(LCP)衬底上具有定向滤波器的准无反射频分复用器(FDM)，用于$E$和$W$波段。串联级联df设计在74,84和94 GHz，每个df由第一层的两条微带线，第二层的两对耦合槽和第三层的环路谐振器组成。优化了df之间的距离以抑制反射和插入损耗，设计了df的不对称分布以获得低轮廓。实验数据表明，所提出的FDM在74 GHz、84 GHz和94 GHz的通频带分别为8.3%、8.8%和9.7%，与仿真结果吻合较好。相应的插入损耗在74、84和94 GHz时分别为3.63、3.4和2.72 dB。该器件在多波段、超宽带通信和雷达系统中具有广泛的应用前景。

Frequency Division Multiplexer With Directional Filters in Multilayer LCP Films at - and -Band

A quasi-reflectionless frequency division multiplexer (FDM) with directional filters (DFs) in multilayer liquid crystal polymer (LCP) substrates is proposed for

$E$

- and

$W$

-band applications. The in-series cascaded DFs are designed at 74, 84, and 94 GHz, each of which comprises two microstrip lines in the first layer, two pairs of coupling slots in the second layer, and loop resonators in the third layer. The distance between DFs is optimized for suppressing reflection and insertion losses, and the asymmetric distribution of DFs is designed to obtain a low profile. The experimental data demonstrate a 3-dB passband of 8.3%, 8.8%, and 9.7% centered at 74, 84, and 94 GHz, respectively, for the proposed FDM, showing a good match with the simulation. The corresponding insertion loss is measured as 3.63, 3.4, and 2.72 dB at 74, 84, and 94 GHz, respectively. The proposed device may find many applications in multiband and ultrawideband communication and radar systems.

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.
