    Abstract: An antenna element includes an insulative substrate including first and second main surfaces arranged in an up-down direction. At least one antenna conductor layer is provided on the first main surface of the insulative substrate. At least one insulative substrate non-forming region is provided between the insulative substrate and the antenna conductor layer in the up-down direction. An insulator layer does not exist in the at least one insulative substrate non-forming region. When seen in the up-down direction, all of an outer boundary of at least one antenna conductor overlaps the at least one insulative substrate non-forming region and is not in contact with the insulative substrate. At least one of the at least one insulative substrate non-forming region includes a void.

    Abstract: A transmission line includes a first structure including a first flexible resin base material, and a first ground conductor thereon, a second structure including a second flexible resin base material, and a first signal line and an interlayer connection conductor in or on the second resin base material, a first spacer between the first and second structures, and a first metal joining material joining the first and second structures with the first spacer interposed therebetween. A first hollow portion is between the first and second structures with the first spacer interposed therebetween. The first signal line and the first ground conductor face each other in a joining direction with the first hollow portion interposed therebetween. The first resin base material and the second resin base material are not in contact with each other. The first metal joining material has a melting point lower than that of the interlayer connection conductor.

    Abstract: A main transmission line includes a substantially elongated dielectric body in which first and second substantially elongated signal conductors are disposed with a distance therebetween in a width direction. A first reference ground conductor and a first auxiliary ground conductor sandwich therebetween the first signal conductor in a thickness direction. A second reference ground conductor and a second auxiliary ground conductor sandwich therebetween the second signal conductor in the thickness direction. The second auxiliary ground conductor includes two substantially elongated conductors and a first bridge conductor, and the second auxiliary ground conductor includes two substantially elongated conductors and a second bridge conductor. The positions of the first and second bridge conductors in a lengthwise direction are different.

    Abstract: An antenna device is configured as a jacket of a communication terminal, such as a mobile terminal, and a communication apparatus includes the antenna device attached to the communication terminal. The antenna device uses an HF-band high frequency signal as a carrier frequency, and is configured as a reader/writer antenna device for a near field communication system. The base body of the antenna device is a plate-shaped base member made of a resin. An antenna coil and a feeding coil are provided integrally with the plate-shaped base member. High-frequency signals are transmitted between the feeding coil and the antenna coil through magnetic coupling in a non-contact manner.
