  • Publication number: 20200028249
    Abstract: An antenna device includes a first antenna and a second antenna provided in a case. The first antenna includes a first capacitance loading element and is configured to at least one of receive and transmit a signal in a first frequency band. The second antenna includes a second capacitance loading element and is configured to at least one of receive and transmit a signal in a second frequency band. The second frequency band is higher than the first frequency band. The second capacitance loading element is disposed at a front side of the first capacitance loading element.

  • 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.

  • Patent number: 8519898
    Abstract: An antenna device includes: an antenna base plate having a shape of a flat plate; a capacity loading plate of a top capacity loaded type monopole antenna, the capacity loading plate arranged in parallel with the antenna base plate; and a planar antenna arranged between the antenna base plate and the capacity loading plate. A size of at least a part of the capacity loading plate in a direction of width of the capacity loading plate is less than about ¼ wavelength of receiving frequency of the planar antenna, and edges of the capacity loading plate in the direction of width of the capacity loading plate are folded back so that the capacity loading plate has a meander shape extending in a direction of length of the capacity loading plate.
