about us

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum ! ! !.

垂直极化和水平极化的接收,是改变馈源的矩形(长方形)波导口方向来确定接收的是垂直极化或水平极化。当矩形波导口的长边平行于地面时接收的是垂直极化。垂直于地面时接收的是水平极化。极化方向(极化角)又因地而异有所偏差。因为地球是个球体,而卫星信号的下行波束却是水平直线传播,这就造成不同方位角所。收的同一极化信号有所不同,所以地理位置不同,所接收的信号极化方向也有所偏差。馈源的长形波导口(极化方向)将不完全垂直或水平于地面。调整极化方向时应注意这一点。
