Abstract
The electronic device includes a device body, a radiation element for performing reception and/or radiation of electromagnetic wave as an antenna to be equipped with the device body, and a dielectric member placed close to or in contact with the radiation element within the device body, the dielectric member being movable from the outside of the device body to shift the resonance frequency of the antenna. According to the present invention, it is possible, for an electronic device such as a notebook PC having a wireless communication function, to compensate the deviations of resonance frequency of antennas caused by errors in mounting of the antennas for individual devices, the difference in the dimension of structures or the like, to match the resonance frequency to the specified central frequency.
