Abstract:
1. A radio communication apparatus configured to be used for first radio communication and second radio communication which are different from each other, comprising: a housing section in which a planar printed circuit board is provided on a base of the housing section; a first antenna configured to be used for the first radio communication, the first antenna being formed by a coil-shaped conductive line wound on a plane of the base of the housing section; a coupling reduction element formed by a plane-shaped conductor and provided to be almost parallel to the plane of the base of the housing section, the coupling reduction element being configured to be put in a condition of electrical floating; a magnetic material sheet provided between the first antenna and the coupling reduction element; and a second antenna configured to be used for the second radio communication, the second antenna being provided to surround a portion of the first antenna and located in a vicinity of a side face of the housing section which is not flush with the plane of the base of the housing section, wherein a plane on which the second antenna is formed is not flush with the plane on which the first antenna is formed and the coupling reduction element is coupled with electromagnetic energy radiated by the first antenna and reduces electromagnetic coupling between the first antenna and the second antenna.
