- Abstract
In this paper, a patch antenna for wireless body area network (WBAN) applications is proposed. Antenna is designed for on-body to Off-body communication that aims to interconnect WBAN with various wireless technologies. It covers three bands for Personal Communication Services (1.2–1.6 GHz), WiMax (3.1–3.4 GHz) and WLAN (5.2–5.8 GHz) in free space. The proposed design is composed of a monopole radiator and defected ground plane. A perfect conducting metal plate is added below the antenna at a gap s to enhance the antenna performance on bio-tissue. Metallic plate acts as a shield for antenna and avoids frequency detuning due to body. Result shows wide bandwidth of 70/330/600 MHz at 1.4/3.2/5.5 GHz frequencies for on body. High directivity of 5.0/7.0/7.50 dBi is observed at 1.4/3.2/5.5 GHz frequencies. In order to consider the health safety, specific absorption rate (SAR) value has been evaluated.
