  • Publication number: 20140320350
    Abstract: An antenna structure includes a feed end, a ground end, a number of antenna units, and a number of connection sections corresponding to the antenna units. The antenna units are positioned side by side. Each connection section is positioned between two adjacent antenna units and interconnects the two adjacent antenna units to form a zigzag-shaped antenna structure. The feed end and the ground end are perpendicularly connected to two antenna units positioned at two ends of the interconnected antenna units.

  • Publication number: 20140152517
    Abstract: An antenna structure for MIMO application includes a substrate, a first antenna element, and a second antenna element. A metal ground layer covers a portion of a first surface of the substrate, and the first antenna element is arranged on the metal ground layer. The first antenna element includes an open-slot, which extending from an edge of the metal ground layer toward an inner portion of the metal ground layer, and a signal feed-in member arranged on a second surface of the substrate and spatially corresponding to an open end of the open-slot. The second antenna element is arranged on the first surface of the substrate adjacent to the first antenna element and extending away from the metal ground layer, and includes a signal feed-in portion arranged adjacent to the open end of the open-slot, and electronically connects to the signal feed-in member.

  • Publication number: 20140111383
    Abstract: A broadband antenna for wireless communication device is disclosed. The broadband antenna includes a main radiator, a grounding unit, a feeding unit, and a resonating unit. The main radiator includes a main radiating portion, a first radiating arm extending from the main radiating portion, and a second radiating arm extending from the main radiating arm, the first radiating arm forms a first current path to generate a first high frequency mode; the second radiating arm forms a second current path to generate a second high frequency mode. The resonating unit is connected to the grounding unit, the resonating unit surrounds and is positioned separate from the second radiating arm, the resonating unit resonates with the main radiator to generate two different low frequency bands corresponding to two coupling currents.

  • Publication number: 20140062803
    Abstract: A wireless communication device includes a housing and an antenna. The housing is made of metal and defines a conductive chamber. The chamber includes a bottom wall, two opposite first side walls, and two opposite second side walls connecting to the first side walls, the first side walls and the second side walls surrounding around the bottom wall. The antenna comprises a radiating body, a feed end, and a ground end. The radiating body is suspended above the chamber and distanced from the conductive chamber in such a way that the antenna functions in a resonance mode with the conductive chamber, in operating at the required frequencies. The feed end and ground end extend from the radiating body and are connected to one of the second side walls.

  • Publication number: 20130113671
    Abstract: A slot antenna includes a substrate, a coupling-feed structure, and a grounding member. The coupling-feed structure is disposed at a top surface of the substrate. The coupling-feed structure includes a first coupling member and a second coupling member. The second coupling member is separately disposed near by the first coupling member. The grounding member is electrically connected to a bottom surface of the substrate and has a slot. A portion of the slot is disposed under the first coupling member and the second coupling member.
