摘要

本文介绍了一种新型雷达用双波段波导天线阵的设计与制作。辐射结构由两组槽组成，在相对的面切入矩形波导，使天线在两个不同的频段上工作。使用这种创新的结构，可以使用独特的结构为不同的雷达应用(如海上导航、监视和通信)执行各种跟踪。采用ANSYS HFSS软件进行了数值计算，结果表明该系统具有S和c两种工作带宽。天线增益在2.25GHz和4.91GHz时分别为14.41 ~ 17.64dBi。

A dual-band slotted waveguide antenna array for radars applications

This paper describes the design and fabrication of a novel dual-band slotted waveguide antenna array for radar applications. The radiation structure is composed by two groups of slots, milled into the rectangular waveguide in opposite faces, enabling the antenna operation over two different frequency bands. Using this innovative structure becomes possible to perform diverse sorts of tracking using a unique structure for different radar applications, such as maritime navigation, surveillance and communications. Numerical results were obtained by ANSYS HFSS and measurements demonstrate two operational bandwidths over the S- and C-frequency bands. The antenna gain varies from 14.41dBi to 17.64dBi at 2.25GHz and 4.91GHz, respectively.
