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.
