摘要

天线间耦合的分析预测往往是费时且昂贵的。当天线工作在低于1ghz的频率上，并且位于仅提供有限地平面面积的表面时，预测是最具挑战性的。本文探讨了使用简单的远场自由空间传输方程来预测在UHF频段工作的两个直升机天线之间耦合的局限性。将飞机上的天线耦合测量值与在消声室中进行的耦合测量值以及使用简单的远场自由空间传输方程计算的天线耦合值进行了比较。

Far-field Techniques For Predicting Aircraft Antenna Coupling

The analytical prediction of coupling between antennas is frequently time consuming and costly. The predictions are most challenging when the antennas operate at frequencies below 1 GHz and are located on surfaces that offer only limited ground plane area. This paper explores the limitations of using simple far-field, free-space transmission equations to predict the coupling between two helicopter-mounted antennas operating in the UHF band. Onaircraft antenna coupling measurements are compared to coupling measurements performed in an anechoic chamber and to antenna coupling values calculated using the simple far-field, free-space transmission equations.
