20080266202 | ANTENNA UNIT - An antenna unit has a first antenna operating at wireless telecommunication bands and a second antenna operating at wireless local area network bands. The first antenna has a first radiating conductor with a first feeding point defining opposite sides, a second, a third and a fourth radiating conductors extending from both sides of the first radiating conductor. A parasitic element defines opposite ends. One end of the parasitic element confronts the free end of the third radiating conductor. A trap circuit connects the fourth radiating conductor and the parasitic element. A second antenna has a third side, a fourth side and a stair-shape side. The connection of the sides of the second antenna forms a first protrusion with a second feeding point and a second protrusion confronting the first antenna. A slot is opened on the second antenna. A ground portion is spaced from the first radiating conductor and the first protrusion. | 10-30-2008 |
20080278389 | Multi-band antenna - A multi-band antenna is arranged on a housing with a first surface, a second surface opposite to the first surface, and a third surface connecting the first and second surfaces, which has a first radiating conductor and a parasitic element formed as an elongated shape and arranged on the first surface. A trap circuit connects the first radiating conductor and the parasitic element. A ground portion is arranged on the second surface. A second radiating conductor is arranged on the third surface and spaced from the first radiating conductor and the ground portion, which is formed as an elongated shape. A feeding conductor with a feeding point connects the first and second radiating conductors. The multi-band antenna obtains a low frequency band through the cooperation of the first radiating, the parasitic element and the trap circuit, and a high frequency band through the second radiating conductor and the parasitic element. | 11-13-2008 |
20090027275 | ANTENNA STRUCTURE - An antenna structure includes a connection portion. A feed portion connecting to the connection portion defines a feed point thereon. An inductance portion extends from the connection portion, and a free end of the inductance portion connects to a ground end. A capacitance portion that is in a long narrow strip shape extends from the connection portion and is parallel with and adjacent to the ground end. And radiating portions connect to the connection portion respectively. The antenna structure employs the inductance portion, the capacitance portion and the ground end to simulate a LC parallel connection to substitute for an inductor and a capacitor. Therefore, the antenna structure achieves an aim of adjusting a resonance frequency and an impedance matching without the inductor and the capacitor, simplifying the design of the antenna structure, decreasing the manufacture cost and attaining a good performance. | 01-29-2009 |
20100117907 | DUAL-BAND ANTENNA - A dual-band antenna includes a first radiating portion, a second radiating portion and a third radiating portion.

The third radiating portion includes a first segment extending in alignment with the first radiating portion from the free end of the first radiating portion, a second segment extending perpendicularly towards the second section from the first segment and spaced away from the first section and a third segment extending perpendicularly back to the first section from the second segment and spaced away from the second section. A feeding point is disposed at a junction of the first, second and third radiating portion. | 05-13-2010 |
20100283685 | MULTI-BAND ANTENNA - A multi-band antenna has a grounding plate with a first end and a second end defined at a longer side thereof. The longer side has an upward first connecting portion adjacent to the first end and a vertical second connecting portion. A feeding portion extends downwards from a lower edge of the second connecting portion. A first antenna radiator extends towards a same direction with respect to the second connecting portion along the grounding plate from an upper side of the second connecting portion. A second antenna radiator includes a first radiating portion, a second radiating portion and a third radiating portion. A third antenna radiator extends parallel to the first radiating portion from a side of the feeding portion. A coupling component includes a first section, a second section and a third section extending opposite to the first section from an end of the second section. | 11-11-2010 |
