20080231519 | MODULARIZED PLANAR ANTENNA STRUCTURE - A modularized planar antenna structure includes an antenna unit, a connection unit, a circuit board and a cover. The modularized planar antenna structure connects the antenna unit and circuit board. The antenna unit includes a signal feeder electrically connected the circuit board at end thereof such that the antenna unit is vertical to the circuit board. The cover is assembled to the circuit to protect the circuit board from electromagnetic interference or strike of external article. When the antenna structure is assembled to a main circuit board of an electronic device, the circuit board can be directly assembled to the main circuit board of an electronic device and the circular-polarized antenna unit points toward zenith direction to receive satellite signal. | 09-25-2008 |
20080238803 | EXTREMELY MINIATURIZED FM FREQUENCY BAND ANTENNA - An extremely miniaturized FM frequency band antenna built in a mobile device includes a substrate and an antenna unit. The substrate is provided with a plate having a grounding metallic surface and a first clearance surface. A second clearance surface provided on the same side of the grounding metallic surface has a metallic micro strip line. One end of the metallic micro strip line extends to a bottom end of the second clearance surface and has a first contact. The other end of the micro strip line extends onto the first clearance surface and has a second contact. Further, a third contact is provided on the first clearance surface at a position corresponding to that of the second contact. Finally, the antenna unit is electrically connected on the second and third contacts to form a FM antenna for receiving FM signals. | 10-02-2008 |
20080278392 | EXTREMELY MINIATURIZED DIGITAL ANTENNA HAVING SWITCHABLE MULTIPLE BANDWIDTHS - An extremely miniaturized digital TV signal reception antenna built in a mobile device includes a substrate, an antenna unit and a switch unit. The substrate is provided with a plate having a grounding metallic surface and a first clearance surface. A second clearance surface is provided on the same side of the grounding metallic surface with a metallic microstrip line for electrically connecting to an output end of the switch unit. Input ends of the switch unit are electrically connected with a plurality of leads of the first clearance surface. The other ends of the plurality of leads are electrically connected with the antenna unit. Finally, when a tuner of a portable digital television switches the channels, signals of the switched channel are simultaneously output to the switch unit. According to the frequency of that channel, the switch unit automatically switches to a suitable range of bandwidth for receiving the digital TV signals, thereby performing the reception of the digital TV signals. | 11-13-2008 |
20100134351 | GPS SIGNAL TRANSMISSION APPARATUS - A GPS signal transmission apparatus includes a DC converter with a GPS power unit and an auxiliary power unit, an external GPS antenna, an RF amplifier and an internal GPS antenna. The DC converter receiving a DC power from a cigarette lighter and supplies electrical power to the RF amplifier, a GPS device through the GPS power unit, and portable electronic devices through the auxiliary power unit. The external GPS antenna receives a GPS signal and the GPS signal is amplified by the RF amplifier and then sent to the internal GPS antenna. Therefore, the GPS signal can be sent to the GPS device in wireless manner by the internal GPS antenna. | 06-03-2010 |
20120020093 | LIGHT UNIT FOR LED LAMP AND METHOD FOR THE SAME - A method for manufacturing a light unit for LED lamp first provides an aluminum substrate, which is surface-treated to form a thin aluminum oxide insulating layer thereon. A circuit board is attached to the insulating layer and includes a through hole to expose part of the insulating layer. An LED die is mounted to the exposed part of the insulating layer, and two bonding wires electrically connect the LED die and the circuit board. A wall is formed on the circuit board to enclose the LED die and the bonding wires. Finally, plastic material is dispensed into the wall to form a lens. | 01-26-2012 |
