Abstract

Koch´s fractal multiband textile antennas are investigated for finding the best placement of antenna on the body. Two different conducting materials as the radiating element are investigated in this work; copper tape and SHIELD IT fabric. The substrate of antenna is a denim textile, which has permittivity of 1.7 and loss tangent of 0.025 at 2.5 GHz. This paper describes the investigation of antenna performance on the human body, which is the chest, the forearm, the arm and the back side of bodies. The comprehensive on-body measurements are conducted with two conditions; human with shirt and human without shirt. The experiment shows the copper tape material is better than SHIELD fabric. The suitable placement of the multiband antenna is on the backside of the body with vertical position.
