New Compact Wearable Systems and Antennas for Medical and IOT Applications

The main goal of Body Area Network, BANs, and Wearable BANs is to provide continuously biofeedback data to the patient and to the medical center. WBANs can record personal information, electrocardiograms, measure body temperature and blood pressure, measure heartbeat rate, arterial blood pressure and other healthcare parameters in an efficient way. For example, accelerometers can be used to sense heartbeat rate, movement or even muscular activity. Efficient small antennas are crucial in the development of wearable 5G communications and medical systems. Low efficiency is the major disadvantage of small antennas. Design and production of compact efficient wearable antennas and sensors is one of the major challenges in production of wearable medical communication systems. Low profile compact antennas and transceivers are crucial in the development of wearable BANs and systems. Development of wearable antennas and compact transceivers for communication and biomedical systems will be described in this presentation. The main goal of Wireless BANs, WBANs, is to provide continuously medical data to the physician, hospitals and to the medical center.

Meta material and fractal technology are used to improve the efficiency and bandwidth of small antennas. Moreover, the dynamic range and the efficiency of communication system may be improved by using active wearable systems. Amplifiers may be connected to the wearable antenna feed line to increase the system dynamic range. New wideband passive and active efficient wearable antennas for IOT, BAN and 5G applications are presented in this paper.

The gain and directivity of the patch antenna with Split-ring resonators, SRR, is higher by 2.5dB than the patch antenna without SRR. The resonant frequency of the antennas with SRR is lower by 5% to 10% than the antennas without SRR. Active small wearable antennas may be used in receiving or transmitting communication, IOT and medical systems. For example, the active wearable slot antenna gain is 12+2dB for frequencies from 1.25GHz to 3.25GHz.
