摘要

介质杆天线(DRA)已被用作反射天线的替代馈电系统。对介电杆天线的模拟辐射特性和实测辐射特性进行了讨论和比较。它是一个圆柱形的聚四氟乙烯棒，从辐射端逐渐变细，由一个圆形金属波导馈电。与喇叭天线相比，这种天线因其制造简单、重量轻、宽带特性以及相对较高的增益和指向性而被使用。本文所讨论的天线实际上是为Ku频段(12-14GHz)设计和测量的，但仿真结果表明，它可以表现出宽带特性，并且可以覆盖两端10-30GHz以上的范围。

Design, development and testing of dielectric tapered rod feed for parabolic reflector antenna as an alternate to feed horns

Dielectric rod antenna (DRA) has been used as an alternate feed system for the reflector antennas. Simulated and measured radiation characteristics for dielectric rod antenna have been discussed and compared. It is a cylindrical Teflon rod tapered from the radiating end and fed by a circular metallic waveguide. Such antennas are being used for their manufacturing simplicity, light weight, broadband characteristics and relatively higher gain and directivity as compared to horn antennas. Antenna discussed here was actually designed and measured for Ku band (12-14GHz) but simulated results reveal that it can exhibit broadband characteristics and can cover the range beyond 10-30GHz at either end.
