摘要

在不同频率下以轴向辐射方式发射的两个圆柱螺旋天线(CHA)具有不同的螺旋直径，并且它们可以以同轴方式彼此内部放置。为了使同轴螺旋天线(COHA)在所需频带内的电气特性与单个同轴螺旋天线的特性相似，在设计时必须确保提高螺旋之间的隔离度。本文研究了COHA的带性质和提高螺旋间隔离度的方法。

Coaxial helical antenna with improved isolation

Two cylindric helical antennas (CHA) being exited in an axial radiation mode at different frequencies have different helix diameters, and they can be placed in a coaxial manner one inside the other. To obtain electrical characteristics of a coaxial helical antenna (COHA) similar to the characteristics of the single CHA in the required frequency band, it is necessary in the design to ensure an improvement in the isolation between the helices. In this work the band properties of a COHA and ways to improve the isolation between helices are considered.
