The separation dependency of the power absorption ratio from the antenna in the millimeterwave band to the human body is analytically obtained by using the theory of a minute antenna and the earth model. The magnitude of the interaction can be estimated by comparing the power absorption ratio when adjacent with that when the antenna is separated enough from the human body. When approaching one wavelength or less for the vertical antenna, the interaction between antenna and human bodies cannot be disregarded. On the other hand, it is permitted up to the quarter wavelength for the horizontal antenna.
