双极化口径耦合微带天线FDTD分析

内容简介：本文应用时域有限差分法(FDTD)分析了双极化口径耦合多层微带贴片天线。文中结果表明，FDTD在分析多层复杂结构的微带天线时是非常有效的。采用Gauss脉冲激励，通过FFT，一次计算就可得到天线谐振频率、耦合、频带宽度、增益等参数的宽频带特性。计算结果对天线的优化设计具有一定的指导作用。

Abstract：a direct three-dimensional finite-difference time-domain (FDTD) method is applied to the full-wave analysis of dual-polarization aperture-coupled microstrip antenna. FDTD is an efficient tool for analyzing complicated structure microstrip antennas.Using Gauss pulse source excitation,the parameters of antenna,such as resonance frequency,return loss,coupling level,gain,etc.can be obtained by FFT.Computed results are useful for optimal design of antenna.
