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.

Summary
Wearable antennas and wearable systems were presented in books and journals; see [1]-[15]. Several of the presented wearable antennas were not measured in the vicinity of human body. Details of measurements in the vicinity of human body are not presented in several of these publications. This paper presents measurements techniques of antennas and RF medical systems in vicinity of human body. An automatic RF medical system tester will be presented in this paper. By employing this antenna tester we do not have to connect or disconnect the sensor ca-. (2016) Wearable Antenna Measurements in Vicinity of Human Body. The automatic RF medical system tester may be applied to measurements of wearable wireless communication systems. In [11] meander wearable antennas in close proximity of a human body are presented in the frequency range between 800 MHz and 2700 MHz
