PED透地通信天线的设计与测量分析

内容简介：井工矿下工作人员与地面保持信息畅通十分重要。针对透地通信中高频电磁波损耗大、低频电磁波干扰强以及大地电参数透地波影响大等问题，根据中频电磁波在地层中的传播特性以及环形天线对中频波的实用性，设计了500 kHz的中频环形天线作为PED透地通信天线，并通过参数测量分析和实际试验验证，达到了预期目标。

Abstract：In consideration of the problem that the communication through earth has great wastage to the high fre-quency electromagnetic waves and great interference to the low frequency electromagnetic waves, and great influ-ence of the earth parameters on electromagnetic waves communication through the earth, and according to the characteristics of the intermediate frequency electromagnetic waves in the earth and the loop antenna applicability to intermediate frequency waves, the paper designed intermediate frequency loop antenna working at 500 kHz as the PED loop antenna to communicate through earth, and achieved the expected goal through measuring its pa-rameters and the experimental verification.
