    摘要： An antenna device is provided in which deterioration of characteristics is prevented and which has improved strength. A chip antenna is inserted into a resin case serving as a support member, and one terminal of the resin case is bonded to a power feeding terminal and another terminal of the case is bonded to a fixation terminal of the chip antenna 2 by solder. The chip antenna is fixed to the resin case so that a gap is provided between the printed circuit board on which the chip antenna is mounted and the chip antenna. Then, by bonding the terminals of the resin case to the printed circuit board by solder, the chip antenna is mounted on the printed circuit board.

    摘要： The antenna array disclosed comprises an undulatory conductor which is capable of transmission and reception of energy, in which the amplitude and pitch of the undulations are progressively altered along the array to produce an array having directional characteristics, and a main lobe to side lobe ratio, which are those of a Dolph-Tchebycheff array. The undulations are circularly arcuate and blended into one another and the conductor is etched from one copper layer of a strip of low loss copper clad laminate, the other layer of which forms a ground plane.

    摘要： According to one embodiment, an antenna device includes a waveguide. The waveguide includes a feed point, and a first region around the feed point. The waveguide is configured to guide a high-frequency signal supplied to the feed point. The waveguide includes a plurality of radiating parts located in the first region. The first region includes a first partial region and a second partial region. The feed point is between the first partial region and the second partial region. A first waveguide wavelength in the waveguide in the first partial region is less than a second waveguide wavelength in the waveguide in the second partial region.
