Abstract

SAR calculation for UWB textile antenna is reported in this paper. This paper presents simulation results of the antenna performance at the conditions of free space and placement at a distance from a portion of a human body. A summary of measurement results of the return loss of the antenna is also included. The simulated S₁₁ parameter shows that the antenna operates within the range 2.25 GHz and 12.19 GHz. The measured return loss has shown that the antenna can operate within 3.04 GHz-10.3 GHz giving a bandwidth of 108%. The performance antenna near to a human body has been simulated and examined. The SAR (10g) has been evaluated using a four-layer body model.
