摘要

本文报道了一种覆盖线介质结构的喇叭天线的辐射特性。这种方法是一种创新的应用于线介质和喇叭天线，人工结构改变了未覆盖喇叭天线的辐射方向图，并观察到一些强烈的影响。介绍了该系统的设计和结构细节，并进行了全波电磁仿真和实验。结构设计和分析在X波段频率范围内(8.2至12.4 GHz)，并在此基础上进行了数值模拟和实验，并与线介质电磁理论一起进行了讨论。

Horn antenna covered with an artificial dielectric structure

The present paper reports on the radiation properties of a horn antenna covered with a wire medium structure. This approach is an innovative application for the wire medium and horn antenna where the artificial structure changes the radiation patterns of the uncovered horn antenna, for which some strong effects are observed. The design and constructive details are presented together with full-wave electromagnetic simulations and experiments. Structural design and analysis are in the X band frequency range (8.2 to 12.4 GHz) whereby numerical simulation and experiment are presented and discussed along with wire medium electromagnetic theory.
