摘要
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。
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.
