  • Publication number: 20210194113
    Abstract: An antenna device includes: a planar antenna; and a metal body arranged a predetermined distance above the planar antenna, wherein the metal body is shifted in a predetermined direction with respect to the planar antenna, wherein the metal body is a metal plate and/or a parasitic element. The antenna device further includes an antenna which corresponds to a frequency band different from that of the planar antenna and a holder configured to maintain the predetermined distance between the planar antenna and the metal body, wherein the antenna is arranged in the predetermined direction.

  • 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.
