ANTENNA APPARATUS AND PORTABLE APPARATUS USING THE SAME

摘要

An antenna apparatus comprising an antenna element formed such that it is significantly shorter in length than the wavelength of a transmitted or received radio wave; a resistor; a matching circuit including at least a reactance element; and an output terminal to be connected to the exterior, wherein these elements are series-connected in the order named. This can provide a small-sized antenna apparatus exhibiting a reduced loss.
