Fabric antenna with body temperature sensing for BAN applications over 5G wireless systems

This paper proposes a fabric-based antenna with body temperature sensing function for communication and sensing by body area network (BAN) applications. The antenna is designed to operate at millimeter-wave (mm-wave) band of 38 GHz, which is a candidate frequency band for future 5th generation (5G) wireless systems. The antenna´s performance is studied in both free space and on-body environments. Due to its relatively high quality (Q) factor, the antenna´s resonant frequency is sensitive to even small variations in the substrate´s dielectric constant induced by the narrow range of temperature changes of the human body.
