摘要

研究了2.45 GHz可穿戴式近距离人体天线的阻抗和辐射特性。本文初步研究了三种矩形微带天线，即洗涤棉天线、聚酯天线和聚酯复合棉天线。这三个天线被假设放置在人体躯干附近，躯干与天线之间的气隙为1mm。在本研究中，人体躯干被建模为一种介电常数和电导率接近人体躯干的有损流体介质，频率为2.45 GHz。结果表明，该可穿戴天线即使放置在人体附近，也能提供所需的阻抗和辐射特性。

Preliminary studies on performance of a 2.45 GHz wearable antenna in the vicinity of human body

Impedance and radiation characteristics of 2.45 GHz wearable antennas in close proximity to a human body are studied in this paper. Three rectangular microstrip antennas namely wash cotton antenna, polyester antenna and polyester combined cotton antenna are considered in this preliminary study. Each of these three antennas is assumed to be placed in the vicinity of human torso with an air gap of 1 mm between torso and antenna. In this study, the human torso has been modeled as a lossy medium of fluid with permittivity and conductivity close to human torso at a frequency of 2.45 GHz. The results obtained indicate that the wearable antenna can provide required impedance and radiation characteristics even when it is placed in the vicinity of human body.
