摘要： A mobile device includes a metal back cover, a dielectric substrate, a grounding metal element, a first radiation element, and a second radiation element. The metal back cover has a slot. The dielectric substrate has a first surface and a second surface, and the second surface faces the slot. The grounding metal element extends onto the first surface of the dielectric substrate. The first radiation element has a feeding point, and is disposed on the first surface of the dielectric substrate. The first vertical projection of the first radiation element at least partially overlaps the slot. The second radiation element is disposed on the second surface of the dielectric substrate. The second vertical projection of the second radiation element at least partially overlaps the slot. An antenna structure is formed by the first radiation element, the second radiation element, and the slot of the metal back cover.

摘要： A mobile device includes an NFC (Near Field Communication) antenna including a metal coil and a first dielectric substrate, a coupling metal element, and a second dielectric substrate. The metal coil is disposed on the first dielectric substrate. The coupling metal element is adjacent to the metal coil. The coupling metal element does not directly touch the metal coil. The coupling metal element is disposed on the second dielectric substrate. The coupling metal element is configured to adjust the operational frequency of the NFC antenna.

摘要： A mobile device includes a metal back cover, a ground metal element, a feeding radiation element, and a dielectric substrate. The metal back cover has a slot. The feeding radiation element has a feeding point, and includes a first feeding branch, a second feeding branch, and a third feeding branch. The second feeding branch and the first feeding branch extend in opposite directions. The third feeding branch and the first feeding branch extend in the same direction. The feeding radiation element has a vertical projection on the metal back cover, and the vertical projection at least partially overlaps the slot. The dielectric substrate is disposed adjacent to the metal back cover. The ground metal element and the feeding radiation element are disposed on the dielectric substrate. An antenna structure is formed by the feeding radiation element and the slot of the metal back cover.

摘要： A communication device includes a dielectric substrate, a first coil antenna, a second coil antenna, and a switch circuit. The first coil antenna has a hollow region. The second coil antenna is disposed inside the hollow region of the first coil antenna. The dielectric substrate is configured to carry the first coil antenna and the second coil antenna. The switch circuit selectively enables at least one of the first coil antenna and the second coil antenna according to a power signal.
