摘要
提出了一种小型化L波段宽带全向盘锥天线,采用不对称椎体结构,使得天线方向图在较宽的工作带宽内实现俯仰面全向覆盖,并可达到波束的上倾。仿真结果表明,天线在0.9~1.8GHz频带内反射系数小于-15dB,在仰角0°时增益大于1dBi,方位面不圆度优于0.5dB。
This paper puts forward a miniature L band broadband omni-direction discone antenna, which uses asymmetric cone structure, makes the omni-directional coverage of antenna directional pattern in pitching plane can be realized in relatively wide operating broadband,and tilted b e a m can be obtained. The simulative results s h o w that the reflection coefficient is less than -15 dB in the band of 0.9 -1. 8 GHz , the gain is greater than 1 dBi at the elevation angle of 0°,and the un- roundess of azimuth plane is less than 0.5 d B .
