摘要

研究了嵌入式垂直馈电的紧凑差分空心介质谐振器天线。一个打印的180°混合大鼠被部署为饲料网络。垂直馈电网络的占地面积非常小，为放置微波元件提供了更多的空间。为了进行演示，设计了一个用于WLAN应用的~2.4 GHz的空心圆柱形差分DRA。利用ANSYS HFSS对反射系数、天线增益和辐射方向图进行了仿真。通过实测验证了仿真结果，结果与仿真结果吻合较好。

Compact differential hollow dielectric resonator antenna with embedded vertical feed

The compact differential hollow dielectric resonator antenna (DRA) with an embedded vertical feed is investigated. A printed 180° hybrid rat-race is deployed as the feed network. The vertical feed network has a very small footprint, giving more space for placing microwave components. For demonstration, a hollow cylindrical differential DRA was designed at ~2.4 GHz for WLAN applications. The reflection coefficient, antenna gain, and radiation pattern were simulated using ANSYS HFSS. The simulated results were verified by measurements, and reasonable agreement between the measurement and simulation is observed.
