Abstract
An antenna for a portable radiotelephone which is configured in consideration of the nature of the electromagnetic wave and of the antenna-user relation in order to improve antenna performance in terms of received gain and directivity. Specifically, this is a multi-directional antenna configuration, including two or more planes of antenna oriented in different directions, for receiving electromagnetic waves in various angles or directions. The invention deals with at least two different cases in order to achieve satisfactory reception by a portable radiotelephone: when an antenna is relatively close to the user or a virtual ground, it should be provided normal to the user, and on the other hand, at another angle or parallel to the user when relatively far from the user or virtual ground.
