摘要
A radio antenna apparatus is provided with an antenna (12) connected with a radio communication circuit (15) that transmits and receives a radio signal. A load impedance element (51) is connected between a parasitic element (13) of an electrical conductor plate and a ground of a housing of a radio communication apparatus including the radio communication circuit. A controller (60) controls an element value of the load impedance element so as to set a current flowing on the housing to be equal to or smaller than a predetermined value when the radio communication apparatus transmits the radio signal, thereby controlling a specific absorption rate (SAR) to be equal to or smaller than a predetermined value.
