Abstract
This paper presents measurements techniques of wearable antennas and RF medical systems in vicinity of human body. The antennas radiation characteristics on human body have been measured by using a phantom. The phantom electrical characteristics represent the human body electrical characteristics. The phantom has a cylindrical shape with a 40 cm diameter and a length of 1.5 m. The phantom electrical characteristics are similar to the human body electrical characteristics. The antenna under test was placed on the phantom during the measurements of the antennas radiation characteristics. The phantom was employed to compare the electrical performance of several new wearable antennas. The phantom was also employed to measure the electrical performance of several antenna belts in vicinity of human body. The results of antenna with thinner belt are better than the results of the same antenna array with thicker belt.
