摘要:
The invention provides a radio device in which multi-resonance promotion and impedance adjustment can be readily performed and a restriction in a mounting space can be dissolved, and an electronic apparatus having the same installed therein. Provision of a stub (123) having a large area and serving as a frequency matching portion as well in a folded monopole antenna (120) results in that a conductor area can be increased, and a resonance frequency can be shifted to lower frequencies. In addition, a frequency of a radio communication antenna can be readily adjusted because the resonance frequency is adjusted by cutting the stub (123).

摘要:
An antenna unit comprising orientation detection means and/or force detection means and an antenna is operable to control its transmission and/or reception characteristic in response to detected orientation of the antenna unit. Absolute orientation of the unit will affect the transmission and/or reception characteristics; in one embodiment changes in orientation and motion will affect these characteristics in order to take account of Doppler effects.

摘要:
There is provided an antenna device of a radio apparatus, including a fed partial element, a folded partial element and an open-ended partial element. The fed partial element is formed to be extended from a fed portion to a first branch portion where the folded partial element branches off. The folded partial element has a grounded end and has a forward path and a backward path short-circuited to each other. The folded partial element and a path on the fed partial element from the fed portion to the first branch portion have a summed length of about a half wavelength of a first frequency. The open-ended partial element branches off at a second branch portion. The open-ended partial element and a path on the fed partial element from the fed portion to the second branch portion have a summed length of about a one-fourth wavelength of a second frequency.
