摘要

本文提出了一种工作在Ku波段和K波段的双波段超宽带(UWB)天线。该天线采用罗杰斯RT5880介质衬底材料，衬底厚度为1.2mm，并设计了不同的矩形槽。采用同轴进给技术，实现更宽的特性。本研究还引入了由于不同的插槽而使电流分布在大部分元件面积上的方法，以获得超宽带特性。所设计天线在高频带谐振频率为16.1 GHz，低频带谐振频率为23.3GHz。利用AnsoftHFSS对天线的回波损耗、驻波比、峰值增益、辐射效率和电流分布进行了仿真分析。该天线非常适合雷达应用，也可用于卫星应用。

Dual-Band UWB Antenna for Radar Applications: Design and Analysis

A dual-band ultra-wide band (UWB) antenna forradar applications is presented in this paper operated at Ku bandand K band frequencies. The proposed antenna is performedwith Rogers RT5880 dielectric substrate material with thicknessof 1.2mm and designed different rectangular slots. It is fed bycoaxial feeding techniques to achieve the wider characteristics. The most of element area the current is distributed because ofdifferent slot has been introduced in this research also to attainthe ultra wideband (UWB) characteristics. The proposed antennaexhibit that the resonant frequency of 16.1 GHz on the higher Kuband frequency and 23.3GHz on the lower K-band frequency. Anextensive analysis of return loss, voltage standing waveratio(VSWR), peak gain, radiation efficiency and currentdistribution of the proposed antenna is simulated using AnsoftHFSS. This proposed antenna is highly suitable for radarapplication also used for satellite applications.
