Abstract
The present invention has an object to provide a portable terminal apparatus capable of reducing that antenna characteristics of respective antenna elements are deteriorated due to antenna coupling phenomena even when a plurality of wireless communication functions are carried out at the same time by utilizing a plurality of antennas. The portable terminal apparatusof the present invention is comprised of: a first wireless unitfor performing a wireless communication by utilizing electromagnetic waves of a first frequency range; a second wireless unitfor performing a wireless communication by utilizing electromagnetic waves of a second frequency range which is different from the first frequency range; a first antenna elementconnected to the first wireless unit; and a second antenna elementconnected to the second wireless unit; and in the portable terminal apparatus, an impedance characteristic of the first antenna elementhas a first frequency characteristic in which at least a characteristic in the first frequency range is superior than a characteristic in the second frequency range; and an impedance characteristic of the second antenna elementhas a second frequency characteristic in which at least a characteristic in the second frequency range is superior than a characteristic in the first frequency range.
