摘要

提出了一种工作在1 ~ 3ghz超高频频段的新型微带定向耦合器。采用三维电磁仿真设计了耦合器。fr4型介电基板因其成本低而得到广泛应用。所提出的定向耦合器提供至少22 dB的指向性，并且在耦合端口处具有- 15 dB的几乎平坦的耦合功率。

Broadband UHF Directional Coupler with High Directivity

A novel microstrip directional coupler operating at UHF band from 1 to 3 GHz is presented. The coupler was designed using 3D electromagnetic simulations. FR4-type dielectric substrate has been used due to its low cost. The proposed directional coupler provides a directivity of at least 22 dB and has an almost flat coupled power of −15 dB at the coupled port.
