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.

  • Publication number: 20080143627
    Abstract: An antenna device includes a printed circuit board and an antenna element. The printed circuit board has a face a portion of which is formed by a conductive layer overlaid with a magnetic material layer made of anisotropic magnetic material. The magnetic material layer is arranged in such a way that a hard magnetization axis of the anisotropic magnetic material is directed almost parallel to the face. The antenna element is arranged almost parallel to the printed circuit board on a side of the face. The antenna element is arranged in such a way that an antenna current distributed on the antenna element if the antenna element is excited is directed almost perpendicular to the hard magnetization axis.

  • Patent number: 7345637
    Abstract: 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).
