Article Synopsis
- - The paper discusses a compact dual-band antenna designed for Wireless Body Area Network (WBAN) applications, using a high-performance semi-flexible substrate and featuring specific dimensions for optimal operation.
- - An artificial magnetic conductor (AMC) supports the antenna, enhancing its performance and isolation from the human body, leading to improved gains and bandwidth at the frequencies of 2.45 GHz and 5.80 GHz.
- - The study utilizes simulation tools like CST Microwave Studio and Ansys HFSS, confirming that the AMC-integrated antenna meets FCC standards for low specific absorption rate (SAR) and demonstrates qualities like low profile and high gain, making it ideal for WBAN use.
The number of wireless sensors in use-for example, the global positioning system (GPS) intelligent sensor-has increased in recent years. These intelligent sensors generate a vast amount of spatiotemporal data, which can assist in finding patterns of movements. These movement patterns can be used to predict the future location of moving objects; for example, the movement of an emergency vehicle can be predicted for health care decision-making.

In this paper, the reflection characteristics of a thin and dual-band metasurface are examined in the microwave frequency regime. The metasurface consists of a 22 × 22 element array of periodic unit cells.
