引言大多数微波天线的远场方向图可以用经典的方法确定,也就是在一个没有电磁干扰的环境(通常是地面反射很小的室外试验场或是微波暗室室内试验场)使天线旋转,并用离开足够远的天线测试其辐射方向图。这个相隔的距离通常是按照2D~2/λ的准则选取的,D是天线最
Introduction The far-field pattern of most microwave antennas can be determined in a classical way by rotating the antenna in an environment free of electromagnetic interference (usually an outdoor test site with a low level of ground reflection or a microwave anechoic chamber test site) Leave the antenna far enough to test its radiation pattern. This distance is usually selected according to the 2D ~ 2 / λ criterion, D is the most antenna
