Abstract(in English) The reduction of the absorbed power by human hands is an important issue for a tablet computer, which is often used in the mobile occasions. In order to reduce the effects of human hands, a unique configuration for a multiple slot antenna system on the metallic frame of a liquid crystal display has been proposed so far. In this paper, parallel feeding structure having power dividing matching network has been proposed in order to achieve the self-compensated power distribution for the efficient radiation of the system. The proposed method has been evaluated numerically by FDTD simulation for various conditions including two feeding methods. It has been found that the minimum relative radiation power is increased by approximately 25 % and the average improvement exceeds 20 % with the proposed feeding method.
