摘要

介绍了一种工作在x波段的x波段圆极化等通量天线。天线结构很简单。它由馈电源和专门设计的介电介质组成，介电介质在馈电源上方加载，用于光束整形。结果表明等流束辐射是成功的。最大增益发生在距轴视方向50度处。在等线波束宽度内，空间轴比优于3 dB。介电高度约为0.57 λ0，其中λ0为中心频率波长。整机结构紧凑，性能优良。

Investigation of an X-Band Circularly Polarized Isoflux Antenna

This paper introduces an X-band circularly polarized isoflux antenna operating at X-band. The antenna structure is quite simple. It is composed of feeding source and specially designed dielectric loaded above for beam shaping. The results show successful isoflux beam radiation. The maximum gain occurs at the 50 degrees away from boresight direction. Additionally, spatial axial-ratio is better than 3 dB within the isolfux beamwidth. The dielectric height is about 0.57 λ0, where λ0 is the wavelength of central frequency. The total structure is compact and performance is good.
