方向性作为天线的一个重要指标,对天线性能和通信距离有着直接的影响。本文以某性天线为研究对象,针对天线的方向性开展了方向性试飞、电脑方向性仿真及实地测试研究,并对各自的优缺点进行对比,对以后此类问题的分析起到很好的借鉴作用。 Directionality as an important indicator of the antenna, the antenna performance and communication distance has a direct impact. In this paper, a certain antenna is taken as the research object, directional test, computer directional simulation and field test are conducted according to the antenna’s directivity. The advantages and disadvantages of each antenna are compared and the analysis of such problems is very good Learn from.
