Design of Textile based Micro strip Antennas for Body Area Network (BAN) at 2.4 GHz ISM band

Abstract

The design of three textile-based microstrip antennas at the 2.4 GHz Industrial, Scientific, and Medical (ISM) band for application in Body Area Networks (BAN) is presented. The proposed antennas are evaluated both in free space and on-body environments, presenting their performance characteristics through important antenna parameters. The use of the same design material and full ground plane are some of the common properties among them. The proposed antenna operates in the closed proximity of a human body, which directs the radiation pattern with a minimum back radiation. The risk of coupling with the human body is reduced by the use of a full ground plane. Moreover, the full ground plane also exhibits the important property of preserving the performance when placed in an on-body environment. The study of fidelity is also provided.
