介绍了一种加粗的套筒单极天线,并作为测向单元使用。运用HFSS电磁仿真软件进行参数优化,在单元驻波与水平面增益满足工程情况下有效降低了天线高度。将这种套筒单极天线组成圆阵,在得出阵列电磁特性的基础上再运用最小二乘法分析了圆阵测向性能。结果表明,该测向天线阵在灵敏度、测向精度及阵列高度上都有一定的优势,特别适合于一些运动平台安装使用。
A bold sleeve monopole antenna is introduced and used as a DF unit. The HFSS electromagnetic simulation software is used to optimize the parameters, which can effectively reduce the antenna height under the condition of unit standing wave and horizontal gain. Based on the electromagnetic properties of the array, a linear array of monopole antennae was formed, and the DFG performance was analyzed by the least squares method. The results show that the directional antenna array has certain advantages in sensitivity, direction finding accuracy and array height, and is particularly suitable for installation and use of some sports platforms.
