Abstract

This letter presents the design of a microstrip-based diplexer for the applications of the Internet of Things (IoT). By incorporating stub-loaded coupled line resonators, the diplexer achieves significant enhancements in its passband performance. Specifically engineered to operate at precise frequencies of 2.55 and 3.94 GHz, the diplexer demonstrates improved isolation and selectivity through the integration of five transmission poles (TPs). A comprehensive analysis is conducted, evaluating crucial parameters, such as size, insertion loss, return loss, and isolation. The diplexer is fabricated on a compact Rogers Duroid 5880 substrate, and experimental measurements validate its effectiveness, exhibiting a low insertion loss of 0.3 dB at 2.55 GHz and 0.4 dB at 3.94 GHz, in close agreement with simulated predictions. The proposed design, featuring stub-loaded coupled line resonators, showcases highly promising passband characteristics, making it a compelling solution for efficient multiplexing of diverse frequency bands in wireless communication applications within the IoT and network-on-chip (NoC) domains.

为基于物联网的应用设计短管负载耦合线路双工器

这封信介绍了一种基于微带的双工器设计，用于物联网（IoT）应用。通过采用存根加载耦合线谐振器，该双工器的通带性能得到显著提升。该双工器专为在 2.55 和 3.94 GHz 的精确频率下工作而设计，通过集成五个传输极（TP）提高了隔离度和选择性。我们进行了全面分析，评估了尺寸、插入损耗、回波损耗和隔离度等关键参数。该双工器是在紧凑型罗杰斯 Duroid 5880 基板上制造的，实验测量验证了其有效性，在 2.55 GHz 和 3.94 GHz 时分别显示出 0.3 dB 和 0.4 dB 的低插入损耗，与模拟预测值非常接近。所提出的设计具有存根加载耦合线谐振器的特点，展示了极具前景的通带特性，使其成为物联网和片上网络（NoC）领域无线通信应用中有效复用不同频段的一个引人注目的解决方案。
