摘要: 本文導(dǎo)出了地面站常用的改進(jìn)型波束波導(dǎo)饋電高效率雙鏡天線的輻射特性的計算式。根據(jù)這些式子可以計算天線的性能;諸如主極化和交叉極化的輻射圖、波瓣峰值、半功率角常數(shù)、相位損失等等。為了適應(yīng)工程上普遍性計算的要求,對上述計算式作了處理,并且根據(jù)一般工程要求進(jìn)行了大量計算,得到便于在工程中應(yīng)用的結(jié)論。

Abstract: In this paper, the equations for calculation of the radiation performances on high efficiency double reflector antenna fed by beam waveguide are derived.Using these equations, the performance of the antenna can be predicted, such as the radiation patterns, the peak values of copolarization and depolarization, the factor of half power beam width, the phase loss and so on.These equations have been reformed to meet the requirements of general engineering eomputation. Some engineering computations are made, and some useful conclusions about the antenna are obtained. -
