ABSTRACT:
A problem of the invention is to provide a small-size communication terminal apparatus capable of reducing an SAR and also widening a band of an antenna and further achieving thinning.The communication terminal apparatus has a substrate (13) disposed inside a housing, a power feeding part (12) disposed in the substrate (13), a monopole antenna (11) having plural elements of multi-frequency sharing, the monopole antenna for feeding power by electrically connecting one end to the power feeding part, and a ground wire (14) electrically connected to a wireless ground of the substrate (13), and the monopole antenna (11) having the plural elements is arranged in a direction vertical to a surface of the substrate (13) and in a back surface direction of the housing so as to be opposed to a human body at the time of a call.
