Abstract

In the paper, investigation of a conformai heterogeneous magnetic antenna (MA) for radio communication on high frequencies is presented. The antenna is constructed to be mounted on moving platforms, which are designed using stealth technologies. Loop 4-port magnetic antenna with lengthwise heterogeneous (piecewise uniform) ferrite core is studied with the finite elements method. The antenna is mounted conformally on two carrier platforms, i.e. flat part of the carrier coating and fuselage of a large aircraft (LA) without fin. The influence of the form of the heterogeneous core and the phase feed modes of the ports of the magnetic antenna on the radiation efficiency and the gain of the “ MA — carrier” system in the frequency band 2–30 MHz is studied. Radiation pattern and expected radiation efficiency of the “MA — carrier” system are shown. It is shown, that usage of the heterogeneous magnetic antenna increases the radiation efficiency of the “MA — carrier” system in comparison with a homogeneous magnetic antenna.

大型飞机上四端口异质共形磁芯磁天线辐射特性研究

本文研究了一种用于高频无线电通信的共形非均质磁天线。天线被构造成安装在移动平台上，该平台采用隐形技术设计。用有限元法研究了纵向非均匀铁氧体铁芯环形四口磁天线。将天线共形安装在两种载体平台上，即大型飞机(LA)无翅的载体涂层平面部分和机身上，研究了磁天线的异质磁芯形式和端口相馈方式对“MA -载波”系统在2 - 30mhz频段辐射效率和增益的影响。给出了“MA -载流子”系统的辐射方向图和预期辐射效率。结果表明，与均质磁天线相比，采用非均质磁天线可提高“毫安载波”系统的辐射效率。
