| Zusammenfassung: | An electronic apparatus comprises an antenna device, a first feeder circuit that feeds a communication signal of a first frequency band to the antenna device, and a second feeder circuit that feeds a communication signal of a second frequency band that is lower than the first frequency band to the antenna device. The antenna device includes a radiation element of an electric field type antenna and a ground conductor disposed so as to face the radiation element. At least one first reactance element is connected between the radiation element and the ground conductor, the radiation element, the first reactance element, and the ground conductor forming a loop unit of a magnetic field type antenna. The radiation element is an antenna element for the first frequency band, and the loop unit is an antenna element for the second frequency band. The entirety of the radiation element is used as an antenna element for the first frequency band. |
