A Novel Design of a 28 GHz 5G NR MSPA Antenna for Body Centric Network

This study presents a design for a 5G NR (New Radio) Microstrip Patch antenna (MSP A) operating in the n257 band, which is more commonly known as the 28 GHz band. The simulations were used to determine its free space properties. The initial findings were optimistic. The antenna produced a 4.26 GHz wide bandwidth with a substantial amount of gain above 6.8 dBi and 74% efficiency. To analyze its on-body performance, a virtual human torso phantom was created, and simulations were done again by placing the antenna over the torso with a 4 mm gap. The antenna sustained its wide bandwidth with a high gain of over 8 dBi. Even in the on-body scenarios, the antenna's efficiency remained close to 70%. The antenna is designed for the 5G-enabled Body Centric Network (BCN), which may be used in a wide range of smart medical applications.
