Design of a textile antenna with artificial magnetic conductor for wearable applications

摘要

With the development of modern wireless technologies and the miniaturization of antennas and electrical systems, the use of antennas on the human body for Wi-Fi applications has become important. However, integrating the antenna near the body immediately raises the question about the protection of the body and the radiation effectiveness of the antenna. One solution that has recently attracted great attention is the use of high impedance surfaces (HIS), which is studied here for the antennas integrated on clothes. Indeed, the HIS greatly reduces the radiation back face of the antenna, thus reducing the value of the specific absorption rate in the presence of the body. In this article, we present a dual-band antenna placed above an artificial magnetic conductor (AMC). The AMC used has the smallest dimensions and makes it possible to obtain the behavior of a perfect magnetic conductor at 2.45 and 5.8 GHz.
