ABSTRACT:
An object of the present invention is to provide an antenna device for a radio apparatus in which the amount of energy (SAR) absorbed by a head of a human body can be reduced without lowering the power of radio waves transmitted during a call. There is provided a board108serving as a base plate of an antenna element, an antenna element102disposed in a longitudinally end portion of the board108through a feeding portion107, a conductor plate109disposed substantially in parallel with a main surface of the board108and disposed on the opposite side to a surface having a sound hole of a receiver portion, and a plurality of short-circuit conductors110disposed on a lower end portion of the conductor plate109. The conductor plate109is short-circuited to a lower end portion of the board108through the short-circuit conductors110.
