摘要

EISCAT - 3D雷达是下一代非相干散射雷达系统，将提供大气和电离层的三维监测。本文重点介绍了eiscat_3d系统天线单元的设计和测试结果。天线单元采用金属十字形天线单元，带有四个刀形阵臂，以减少降雪量。在元件顶部增加了一个十字形寄生片，以减少阵列中天线的主动反射损耗。仿真结果表明，在整个218 ~ 248mhz频段内，单天线在各扫描角的主动反射损耗<-12.1dB，单天线的被动回波损耗优于-17.5 dB。

A New Metal Crossed Dipole Antenna for the EISCAT_3D Radar

The EISCAT _3D radar is the next generation incoherent scatter radar system which will provide 3D monitoring of the atmosphere and ionosphere. This paper focuses on the design and test results of the antenna element for the EISCAT _3D system. The antenna element adopts a metal cross-shape antenna element with four knife-shaped array arms to reduce snowfall accumulation. A cross-shape parasitic sheet is add to the top of the element to decrease the active reflection loss of the antenna in the array. The simulated results showed that the active reflection loss for all scan angles in the transmitting band is <-12.1dB, and the passive return loss a single antenna are better than -17.5 dB in whole 218-248MHz.
