In this study, we developed active radar antenna including periodic structure built by conductor to reduce direct electromagnetic coupling between transmitter antenna and receiving antenna. Form the simulation results; the coupling was reduced more than 35dB. Furthermore, the effectiveness of proposed antenna structure was also confirmed for detecting shallow object. The effectiveness is also confirmed by experimentally.

在本研究中，我们发展了一种主动式雷达天线，其包含由导体所建构的周期性结构，以减少发射天线与接收天线之间的直接电磁耦合。从仿真结果来看，耦合度降低了35dB以上。此外，所提出的天线结构的有效性也被证实用于检测浅目标。实验结果也证实了该方法的有效性。
