Abstract

In this paper, an ultra-wideband (UWB) and high gain horn antenna is proposed for microwave communication system, which is composed of E-plane horn antenna, a dielectric hemispheric lens and double wedge metal ridges. The proposed antenna is fed by coaxial feed, which is simulated by high frequency structure simulator (HFSS) software. The simulated results show that the double wedge metal ridges increase the bandwidth of the horn antenna, and the frequency range up to 2~12GHz. When only the double wedge metal ridges are applied to improve the performance of the horn antenna, the gain of the horn antenna will be reduced. In order to compensate for the effect of the double wedge metal ridges on the gain of the horn antenna, the dielectric hemispheric lens is utilized. According to the simulated results, the gain of horn antenna can be increased by the dielectric hemispheric lens in the working frequency band. By the proposed techniques, the proposed antenna has the characteristics of ultra-wideband, high gain and strong directional radiation. It can be applied in a variety of communication systems.

带透镜和楔脊的宽带高增益喇叭天线

本文提出了一种用于微波通信系统的超宽带高增益喇叭天线，该天线由e平面喇叭天线、介电半球透镜和双楔金属脊组成。该天线采用同轴馈电方式，利用高频结构模拟器(HFSS)软件对馈电过程进行了仿真。仿真结果表明，双楔形金属脊增加了喇叭天线的带宽，频率范围可达2~12GHz。如果只采用双楔金属脊来提高喇叭天线的性能，会降低喇叭天线的增益。为了补偿双楔金属脊对喇叭天线增益的影响，采用了介质半球透镜。仿真结果表明，在喇叭天线工作频带内采用介质半球透镜可以提高天线增益。通过所提出的技术，所设计的天线具有超宽带、高增益和强定向辐射的特点。它可以应用于各种通信系统中。
