Abstract
This paper describes a simple analysis tool for calculating the power density on a cylindrical surface in the Fresnel region in front of an antenna array. The tool is used to calculate the radiation exposure in front of a stationary or rotating antenna. Huygens´ principle is applied to extend the analysis to reflector antennas.
