摘　　要：文中应用矩量法和一致性几何绕射理论的混合方法,研究有限导电平面上单极子天线间的电磁耦合问题,分析各有限导电平面尺寸及缝隙对耦合的影响,提出了减小电磁耦合的一种新方法。计算结果表明,合理地选取导电平面尺寸能使天线间的耦合变小;导电平面上开有半波长的多缝隙也可较好地降低耦合,而缝隙的宽度和间隔对耦合的影响较小。The hybrid approaches of MoM and UTD is used to study the electromagnetic coupling between monopoles on the bounded conducting planes. The effect on the coupling of the size of the conducting planes and the slots is analyzed. And a novel method for reducing the coupling is presented. The calculation results show that prop- er size of each bounded conducting plane can make the coupling smaller, and lots of the half wavelength slots excava- ted on the bounded conducting planes can also reduce the coupling well, but the effect of the width and the space of the slots on the coupling is little.
