  • Publication number: 20140104121
    Abstract: An electronic device including a first casing, a second casing, at least one first connecting unit and at least one feeding unit is provided. The first casing includes a conductive material. The second casing includes a conductive material. The first casing and the second casing are conducted with each other through the first connecting unit. The feeding unit is electrically connected to the first casing and has a feeding point and a capacitor component, wherein the capacitor component is connected with the feeding point, and the electronic device forms an antenna structure with the first casing, the second casing, the first connecting unit and the feeding unit and transmits an electromagnetic signal via the feeding unit.

  • Patent number: 8698673
    Abstract: A multiband antenna includes a ground plane, a dielectric substrate and a radiating metal portion. The dielectric substrate is located at one side edge of the ground plane. The radiating metal portion is disposed on one surface of the dielectric substrate and includes a first metal portion and a second metal portion. The first metal portion is substantially of an L-shape. One end of the first metal portion is adjacent to the side edge of the ground plane and is the antenna's feeding point connected to a signal source, and the other end of the first metal portion is an open end. The second metal portion comprises a U-shape portion. The second metal portion includes a first open end and a second open end, which are respectively located on two opposite sides of the open end of the first metal portion.

  • Patent number: 8223083
    Abstract: A multiband monopole slot antenna includes a ground plane, a dielectric substrate, a radiating portion, and a microstrip feedline. The dielectric substrate is connected to an edge of the ground plane and extends toward the opposite direction of the ground plane. The radiating portion is on the metal surface of the dielectric substrate and includes a first monopole slot, a second monopole slot and a third monopole slot. The microstrip feedline is on the surface opposite to the metal surface of the dielectric substrate. A first end of the microstrip feedline is connected to a signal source, and a second end of the microstrip feedline is an open end. The microstrip feedline passes over the first, second, and third monopole slots. A section of the microstrip feedline which passes over the third monopole slot is parallel to the third monopole slot, and the microstrip feedline is generally of a step shape.
