Patch Array Antenna for Health Care and Monitoring System

Abstract

Health Care is the biggest challenge in today's world. There is a huge gap between the population and the number of health care professionals. One of the possible solutions can be a remote health monitoring system which is better known as telehealth. This paper deals with the design of antenna which will serve as the transmitter unit of the health care monitoring system which is fitted with the patient’s body. The paper describes a Swastik shaped antenna operating at a frequency of 3.5 GHz. The designed antenna shows efficiency of 93.8% with a simulated gain of 9.08 dB and a reflection coefficient of -23.50 dB. In this work, the two sides of Swastik (right and left part) are designed separately and then both were merged to have a complete design. The results show a considerable increase in the gain of the overall antenna as compared to the right side or left side of the swastika design.
