馈线损耗

一种计算毫米波微带天线阵馈线损耗的方法

A Method of Calculating Millimeter Wave Microstrip Antenna Array Feed Line Loss

本文讨论了来自于宇宙空间的噪声辐射和天线及馈线损耗产生的内部噪声机理及天线接收系统品质因素G/T值的计算方法。

Ive discuss several aspects of the subject on noise in this article : noise rediation coming from the outer space ; the process that noise produces due to the feeder and antenna loss ; the characteristics of the antenna receiving system , and the calculation of the G / T.

该系统能适应弱环网等复杂的配网运行方式，并能快速准确地计算出低压配网中每条馈线的功率损耗情况，为低压配网线损的分析与管理提供可靠的基础。

It can calculate the power losses of each feeder rapidly and correctly and provide reliable foundation for the analysis and management of the power losses in low voltage distribution network .

阵列天线辐射单元采用空气介质的微带贴片天线，辐射效率高；阵列天线的馈线网络采用低损耗的空气带状线形式，降低了馈线损耗。

The radiating element of array antenna is air dielectric microstrip patch antenna , which has high efficiency , and the feed network is low loss air strip , which can reduce the loss of the feed line .
