金属挡板对共面天线隔离效应的试验研究

Experimental Study on the Isolation Effect of Metal Plate on Coplanar Antenna

舰船共面天线之间会产生一定程度的耦合,理论上讲,采用金属挡板能够直接阻隔这耦合,从而达到提升天线隔离度的目的。论文首先从理论上分析了金属挡板的作用机理,然后对通过试验研究了金属挡板不同高度的情况下,挡板两侧共面天线间隔离度的变化规律。当挡板达到一定高度后,隔离度有明显的改善效果。

There is a certain degree of coupling between the coplanar antennas of the ship. Theoretically,the metal plate can directly block the coupling,so as to improve the isolation of the antenna. Firstly,the mechanism of the metal plate is analyzed theoretically,the relationship between the isolation of coplanar antennas and the height of metal plate is studied. The results show that the isolation of coplanar antennas has obvious improvement when the plate reaches a certain height.
