The wireless body area networks (WBAN) have received much interest from researchers in the field of medical application in recent years such as heart rate, temperature monitoring and blood pressure. In this study, a new antenna design with a low profile or easy fabricates introduced (WBAN) applications. In this work, a metasurface technique was used to improve the antenna characteristics, including return loss, gain and radiation patterns. The designed structure, and numerical analysis have been performed by using Computer Simulations Technologies (CST) microwave studio. The structure of the antenna a composite of three layers from top to bottom as follows: radiation copper patch, felt substrate and ground copper. The key idea for this work is loading the MTS structure of a 5 × 5 unit cell to the designed antenna to enhance the antenna parameters. The overall structure thickness is 4.68 mm and the antenna operates between 6 and 14 GHz. According to the results, for the simulation and measurement, the gain increased from 7.33 dBi to 7.47 dBi and from 10.23 dBi to 11.1 dBi with and without MTS, respectively. The antenna was investigated in free space and on a human body both numerically, and experimentally. In addition, the bending evaluation was investigated. The novelties of this work are high gain, wide-band, directional radiation pattern, small size, low profile, and easy fabrication. The experimental, and simulation results are in good agreement. We believe this work can be helpful in future medical applications.
