Absorption of electromagnetic (EM) radiation by the human body has received tremendous attention due to rapid growth in Wireless Body Area Network (WBAN) applications. Specific Absorption Rate (SAR) is usually measured with the antenna in flat condition. However the emergences of flexible wearable textile antennas make it compulsory to analyse the SAR when the antenna is not in its normal flat condition. The absorption of EM radiation as well as the SAR distribution are analysed as a function of the antenna curvature sizes and different on-body locations and distances. The averaged SAR values demonstrate an increase of up to 92.3% when the curved textile antenna is bent and placed 1 mm away from the body.
