| 摘 要： | 文章介绍了宽波束圆极化天线的应用背景,简述了近些年来国内外相关文献实现宽波束圆极化天线的几种方法。这些方法均能有效拓展天线的半功率波束宽度及轴比的波束宽度,其中天线形式主要包括四臂螺旋天线、微带天线、缝隙天线以及振子天线。最后对这些方法进行了对比归纳,并展望了宽波束圆极化天线的发展前景。

| Abstract: | In this paper,the background about the application of wide-beam circularly polarized antennas is reviewed.Methods in recent literature for increasing the beamwidth are summarized,which could effectively improve the half-power beamwidth and axial ratio beamwidth smaller than 3 dB.In these methods,three antenna forms are involved which are quadrifilar helix antenna,microstrip antenna and slot antenna.Finally,comparisons about these methods are conducted and future development of the circularly polarized wide-... |
