基于PSOFDTD的波导缝隙天线优化设计

内容简介：设计了一种16阵元波导缝隙天线,其阵元在波导宽边中心线一侧排列.该设计采用泰勒分布进行阵列综合,利用粒子群优化算法( PSO)与时域有限差分法( FDTD)在不同偏置位置对谐振长度进行优化.由于该天线属于非谐振式波导缝隙阵,设计的关键是调整缝隙对宽边中心线的偏移.仿真结果表明天线指标与设计要求吻合,证明了设计方法的可行性.

Abstract：@@@@A 16 elements array waveguide slot antenna is designed whose units are arranged in one side of the center line . The design is guided by Taylor Distribution, and particle swarm optimization algorithm( PSO) and the finite difference time domain method( FDTD) are used for slot resonance length optimization . As waveguide slot antenna is disresonance, the committed step is to adjust offset between slot unit and the center line . The test results show that the parameters meet requirement, and the method is feasible .
