摘要

本文介绍了一种低成本的小型微带超宽带天线,该天线用于卫星和雷达通信系统,具有滤波特性和多波段特性。超宽带天线由变形接平面的改进矩形辐射单元组成,提供5 ~ 16ghz的宽带。在辐射贴片中引入u型槽,分别获得覆盖C、X和Ku波段的三波段频率响应。实现的频段为4.9-7 GHz、7.92-11.08 GHz和11.85-15.94 GHz。利用CST MWs对所提出的天线进行了成功的仿真,并进行了实验验证,以证明这些天线的性能。

Ultra wideband and tri-band antennas for satellite applications at C-, X-, and Ku bands
In this paper, a low-cost compact microstrip ultra wideband antenna for satellite and radar communication systems with filtering properties resulting multiband characteristics is presented. The ultra wideband antenna consists of a modified rectangular radiating element with deformed ground plane which provides a wide bandwidth from 5 to 16 GHz. The U-shaped slots are introduced in the radiating patch to obtain the tri-band frequency response covering C, X and Ku bands separately. The frequency bands achieving are 4.9-7 GHz, 7.92-11.08 GHz and 11.85-15.94 GHz. The proposed antennas are successfully simulated and performed using CST MWs and experimental validation are presented to demonstrate the performance of these antennas.
