Abstract
A multi-antenna system for the CDMA Handy Phone that can reduce the influence of the user´s hand is proposed. The proposed multi-antenna system is composed of two antenna elements and a power divider without any switching circuits. As the two antenna elements are always fed by the divided power, high radiation efficiency can be kept even if the one antenna element is wrapped by the hand.
