20100019973 | MULTI-BAND ANTENNA - A multi-band antenna has a grounding plate, a radiating element and a parasitic element. The radiating element has a level radiating portion disposed a predetermined distance away from the grounding plate and a first connecting portion connecting the level radiating portion with the grounding plate. The parasitic element has a substantially L-shaped parasitic portion away from the grounding plate and a second connecting portion disposed at the same side of the grounding plate with the first connecting portion to connect a free end of the L-shaped parasitic portion with the grounding plate. The L-shaped parasitic portion is substantially at the same plane with and spatially fences the level radiating portion to define a substantially L-shaped space. The multi-band antenna has simple structure and small size to be assembled in the limited space of notebook. | 01-28-2010 |
20100060525 | MULTI-BAND ANTENNA - A multi-band antenna includes a feed-in element having a feed-in point thereon. A first connecting portion extends from one side of the feed-in element. A ground element connects to a side of the first connecting portion and is parallel to the feed-in element. A holding portion perpendicularly extends from a side of the ground element opposite the first connecting portion. A second connecting portion perpendicularly bends and extends from a side of the feed-in element opposite the first connecting portion. A first radiating portion extends from one side of the second connecting portion. A second radiating portion extends from the other side of the second connecting portion opposite the first radiating portion. The first radiating portion and part of the second radiating portion are disposed at one side of the holding portion. The rest part of the second radiating portion is disposed at the other side of the holding portion. | 03-11-2010 |
20100171664 | DUAL-BAND ANTENNA - A dual-band antenna has a feeding portion including a first feeding portion and a second feeding portion extending perpendicularly from a top of the first feeding portion. A first high-frequency portion spaced away from the second feeding portion extends upwards from the first feeding portion, and a second high-frequency portion extends perpendicularly from the first high-frequency portion and located at a same side with respect to the first feeding portion as the second feeding portion. A first low-frequency portion located at a same side with respect to the first feeding portion as the second high-frequency portion extends perpendicularly from an end of the first feeding portion. A second low-frequency portion extends upwards from the first low-frequency portion. A third low-frequency portion extends back to the first low-frequency portion from the second low-frequency portion. A grounding portion connected with the feeding portion by a connecting portion faces the low-frequency radiator. | 07-08-2010 |
20100253584 | Antenna apparatus - An antenna apparatus includes a housing defining a plurality of walls and a plurality of included angle spaces between the walls. An inner surface of one of the walls is configured a telecommunication antenna. One of the included angle spaces opposite to the wall on which the telecommunication antenna is configured a global positioning system antenna. A broadcast receiving antenna positions in the housing and between the telecommunication antenna and the global positioning system antenna. Because the telecommunication antenna and the global positioning system antenna position away from each other, the interference therebetween will be reduced. | 10-07-2010 |
20100265157 | Multi-band antenna - A multi-band antenna includes a base plate having two opposite transverse edges and two opposite longitudinal edges respectively connected to the two transverse edges. A high frequency radiating element and a capacitance element are respectively bent downward from the two transverse edges of the base plate and then extend in a transverse direction. A feeding point is defined at one end of the capacitance element adjacent to the base plate. A low frequency radiating element extends from one longitudinal edge of the base plate. An inductance element extends from the other longitudinal edge of the base plate and has a transverse border exceeding the base plate in a longitudinal direction. A grounding element is bent downward from the transverse border of the inductance element and then extends in the same direction as the high frequency radiating element to be spaced from the capacitance element. | 10-21-2010 |
