加载对垂挂式长波天线电气性能影响的研究

Electrical Performance Influence of Loading on Inverted Long-wave Antenna

在借鉴机载长波天线、气球天线和COCO天线的基础上,建立三种形式的垂挂式长波发信天线模型,然后就顶容性加载和电感加载两个方面研究顶容线数量以及电感加载位置、加感量等对天线电气性能的影响。仿真结果表明:顶容性加载和电感加载均能使天线的阻抗特性和辐射性能得到改善,且电感加载能够间接缩短天线物理长度。这一研究结果对改善长波天线电气性能、缩短天线物理长度等具有重要的指导意义。

Based on the airborne long-wave antenna, kptoon and COCO antenna. The three types of inverted long-wave antenna model are established. The influence of capacitive loading and inductance loading, particularly of the top-line number, inductance loading position and quantity on antenna electrical performance, is fairly studied. Simulation shows that the capacitive loading and inductance loading could improve impedance characteristic and radiation property of the antenna, while the inductance loading shortening the physical length of antenna. This research result has a guiding significance in electrical performance improvement and physical length shortening of the antenna.
