| 摘 要： | 提出一种新型的圆极化全向天线,其仿真在12%的频带宽度内电压驻波比小于2,中心频率的水平面全向辐射圆极化增益起伏小于0.25dB,圆极化轴比小于4.2dB,增益大于1.3dB。测试结果表明,在39%的频带宽度内电压驻波比小于2,中心频率的水平面全向辐射圆极化增益起伏小于0.4dB,圆极化轴比小于6.5dB,比较容易组阵。这种天线在个人通信系统和地面控制系统中有较强的实用价值。

| Abstract: | In this paper we design a novel circular polarized omni-directional symmetric dipoles antenna,simulation results indicate that the 2:1 Voltage Standing Wave Ratio(VSWR) bandwidth of antenna is greater than 12%,the omni circular gain undulation at the horizontal plane of the center frequency is less than 0.25 dB,the circular axial ratio is less than 4.2 dB and the gain is greater than 1.3dB.The experiment results explain that the VSWR is less than 2 in a 39% bandwidth,the omni circular gain undulation is less than 0.4dB and the circular axial ratio is less than 6.5 dB.Also it is easy to form an array with this kind of antenna,which can be used in the personal communication system and the ground control system. |
