一种基于粒子群算法的长波天线顶负载优化研究
An Optimization of Long-Wave Antenna Top Load Based on Particle Swarm Optimizer

长波发射天线一般可等效为单极子顶加载天线，顶负载起着改善电流分布、增大天线静态电容及功率容量、提高天线有效高度等效果，在天线设计中起着关键作用，但如何平衡各项指标之间的关系，保证最终设计的最优化，这是需要重点研究关注的问题。本文采用粒子群算法对顶负载设计状态进行优化，并通过计算实例进行计算验证，可以实现一定限定范围内的最优化设计，为实际工程设计提供了研究基础及思路。
The Long-wave transmitting antennas are generally equivalent to monopole top loading antennas. Its top load plays the role of improving the current distribution, increasing the static capacitance and power capacity of the antenna, and increasing the effective height of the antenna. Top load plays a key role in antenna design. However, how to balance the relationship between various indicators and ensure the optimization of the final design, this is a problem that needs to be focused on research. In this paper, the particle swarm optimization algorithm is used to optimize the design state of the top load, and the calculation example is used to verify the calculation, which can realize the optimal design within a certain limited range, and provide the research basis and ideas for the actual engineering design.
