零张角对数周期偶极子(ZLPD)天线是一种极宽频带天线,因其几何结构特点,其电特性随频率对数而周期性变化,目前该类天线广泛应用于短波、超短波、微波等波段的通信、测向、电子对抗等军民航设备天线中。研究该类天线的结构参数与性能特点,确保通信、导航、电子对抗设备工作效能的发挥非常必要。文中针对零张角对数周期偶极子天线的数学模型进行了技术分析,研究了各偶极子辐射场间相位关系,提出并分析了相位补偿技术对天线工作频带的影响,研究结论对调整与使用该类天线的技术性能具有一定的指导意义。
The zero-angle logarithmic period dipole (ZLPD) antenna is an extremely wide band antenna. Because of its geometric structure, its electrical characteristics change periodically with the logarithm of frequency. Currently, such antennas are widely used in shortwave, ultrashortwave, Microwave and other bands of communications, direction finding, electronic warfare and other military and civil aviation equipment antenna. It is very necessary to study the structural parameters and performance characteristics of this type of antenna so as to ensure the working efficiency of communication, navigation and electronic countermeasures equipment. In this paper, the mathematical model of logarithmic periodic dipole antenna with zero-angle angle is analyzed. The phase relationship between each dipole radiation field is studied. The influence of phase compensation technology on the working frequency band of antenna is proposed and analyzed. And the technical performance of using this type of antenna has some guiding significance.
