  • Patent number: 10978794
    Abstract: An antenna device to be mounted to a vehicle roof, includes: a case unit having an accommodating space formed therein and having a radio wave permeability; and an antenna unit to be accommodated in the accommodating space, wherein the antenna unit has: a pair of capacitance loading elements facing across a plane, as a center, perpendicular to the vehicle roof at a predetermined interval and at a predetermined angle to each other; a coupling portion provided at a portion lower than an upper edge of the pair of the capacitance loading elements to conduct each of the pair of capacitance loading elements each other via each of the coupling portions; and a helical element electrically connected to the coupling portions.

  • Publication number: 20190379109
    Abstract: An antenna device includes a case, a first antenna and a second antenna including a capacitance loading element. The capacitance loading element includes a turning-around area turning around in a front-rear direction on at least one of a front side and a rear side thereof. When the turning-around area is provided on the front side, at least part of the first antenna is situated in front of the turning-around area. When the turning-around area is provided on the rear side, at least part of the first antenna is situated behind the turning-around area. When the turning-around area is provided on the front side and on the rear side, at least part of the first antenna is situated at least one of in front of the turning-around area on the front side and behind the turning-around area on the rear side.

  • Publication number: 20190027819
    Abstract: An antenna device which includes a plurality of antennas in a common case and is capable of achieving downsizing while suppressing a decrease of an antenna gain, is provided. An antenna device includes a TEL antenna and a capacity loaded element in a common case. The capacity loaded element is located above the TEL antenna. A length of the capacity loaded element is a positive integer multiple of one-half a wavelength of a PCS band. The TEL antenna is arranged so as to avoid a voltage maximum point of a standing wave, of the PCS band, generated in the capacity loaded element.
