In this paper, the interaction between a single band textile antenna with human body is examined. The simulations are performed by means of CST Microwave Studio with a single band 2.4 GHz patch dipole antenna as the radiating source. The effects of bending and different distances from the body are also considered in this study. Results have clearly indicated that the human body has notably shifts the antenna resonant frequency and modifies the radiation pattern at the frequencies investigated. Furthermore, the results obtained show that the SAR values are significantly influenced by the amount of curvature of the antenna and the separation distance between the antenna and the human body. The averaged SAR value is increased up to 92.3 % when the curved textile antenna is bent and placed 1 mm away from the body.
