Abstract

It is known, that a slot antenna, placed immediately on the ground surface, provides low radiation into the air and low coupling between transmitting and receiving antennas. A "front to back ratio" is much greater then that for an electric dipole. This work is devoted to the investigation of a slot antenna (Fig. 1), placed at a small height h<0.02-0.05 /spl lambda/ above the ground surface.

地质雷达用槽天线特性分析
众所周知,直接放置在地面上的槽形天线对空气的辐射很低,发射天线和接收天线之间的耦合也很低。“前后比”比电偶极子大得多。这项工作致力于研究一个槽天线(图1),放置在地面以上的小高度h<0.02-0.05 /spl lambda/。
