植入式设备作为通信工具已经被极大地研究。这些可植入装置嵌入人体或宠物体内。重要信息（如体温、血压、心跳等）可以通过使用无线通信链路从可植入装置传输到外部设备。因此，对植入式天线（植入式天线）的研究具有重要意义。提出了一种用于短距离无线通信的植入式H形腔体缝隙天线。这种类型的天线，这是设计工作在工业科学医疗频段（2.45 GHz），研究通过使用时域有限差分计算。我们分析了所提出的天线，这是嵌入到人体之间的肩膀和手肘的性能。然而，由于所提出的天线太小，无法制造，因此采用比例模型进行天线测量。利用2/3肌肉等效体模对天线缩比模型的一些特性进行了计算和测量。结果表明，所提出的天线有希望在植入物中使用。
Implantable devices have been investigated with great interest as communication tools. These implantable devices are embedded into the human or pet body. The vital information (such as temperature, blood pressure, cardiac beat, etc.) can be transmitted from implantable devices to the external equipment by use of a wireless communication link. Therefore, the research on the antenna for implantable devices (implanted antennas) is very important. This paper proposes an implanted H-shaped cavity slot antenna for short-range wireless communications. This type of antenna, which is designed to operate at the industrial-scientific-medical band (2.45 GHz), is investigated by using finite-difference time-domain calculation. We analyzed the performances of the proposed antenna which is embedded into the human body between the shoulder and the elbow. However, since the proposed antenna is too small to fabricate, a scale model is adopted for antenna measurements. Some characteristics of the scale model of the antenna are also calculated and measured by using the 2/3 muscle-equivalent phantom. The results show that the proposed antenna has promise for use in an implant.
