20130154900 | WIRELESS COMMUNICATION DEVICE HAVING METAL END PORTION OF HOUSING THEREOF - An exemplary wireless communication device includes a circuit board, a metal end portion, an antenna, and a connecting member. The antenna is positioned on the circuit board. The connecting member interconnects the circuit board and the end portion. The connecting member serves as a feeding point of the antenna. The end portion is a portion of a housing of the wireless communication device and further serves as a radiating portion of the antenna. | 06-20-2013 |
20130169507 | WIRELESS COMMUNICATION DEVICE WITH SENSOR-BASED ANTENNA SELECTION - An exemplary wireless communication device includes a housing, a first antenna, a second antenna, a switch, and a radio frequency (RF) circuit. The housing includes a first holding portion corresponding to the second holding portion and a second holding portion corresponding to the first holding portion. The RF circuit is selectively connectable to the first antenna or the second antenna via the switch. The sensor is electrically connected to the switch. The sensor senses a state of the housing, wherein the state of the housing is one of position of the housing and proximity of a user's hand to one of the first antenna and the second antenna, and the sensor controls the switch to select the first antenna or the second antenna to connect to the RF circuit to transmit and receive signals wirelessly according to the sensed state of the housing. | 07-04-2013 |
20130241786 | ANTENNA ASSEMBLY - An antenna assembly includes a carrier, a metal sheet, and an antenna. The metal sheet is attached to the carrier and defining at least one notch. The antenna is connected to the metal sheet and includes a radio body for receiving and transmitting wireless signals. The radio body is positioned above the metal sheet. The length of current path in a peripheral wall of the at least one notch is in a predetermined proportion to the wavelength of the wireless signals, enabling the metal sheet to resonate with the radio body to increase the bandwidth of the antenna. | 09-19-2013 |
20130259486 | WIRELESS COMMUNICATION DEVICE - A wireless communication device includes a first antenna, a second antenna, a first light sensor adjacent to the first antenna, a second light sensor adjacent to the second antenna, a controller, and a magnetic member movably located between the first antenna and the second antenna. When one of the first and second antennas in a state of receiving/transmitting wireless signals is covered by a user's hand, the nearby light sensor sends a pulse signal to the controller. The controller receiving the pulse signal controls the first and second antennas to change their magnetic polarity, enabling the magnetic member to be separated from one of the first and second antennas and attached to the another one, thereby choosing one of the first and second antennas, or a combination of one of the two antennas and the magnetic member to receive/transmit the wireless signals. | 10-03-2013 |
20140327592 | ANTENNA STRUCTURE AND WIRELESS COMMUNICATION DEVICE EMPLOYING SAME - An antenna structure includes an antenna and a metal member located between the antenna and an electronic member. The antenna is configured for receiving and sending wireless signals. An electrical length of the metal member is greater than or equal to a quarter wavelength of a resonance frequency band of the antenna. The metal member transmits wireless signals generated by the electronic member to ground to prevent signals generated by the electronic member from interfering with the antenna. | 11-06-2014 |
20140333487 | WIRELESS COMMUNICATION DEVICE - An exemplary wireless communication device includes a circuit board, a first antenna, a second antenna, and an end portion. The circuit board includes a feed terminal. The first antenna is located on the circuit board adjacent to the feed terminal. The second antenna is electronically connected to the feed terminal. The end portion serves as a portion of a metal housing of the wireless communication device and includes a positioning portion. The positioning portion secures the first antenna and the end portion to the circuit board. | 11-13-2014 |
20140368402 | ANTENNA STRUCTURE AND WIRELESS COMMUNICATION DEVICE USING THE SAME - An antenna structure includes a feed section, a ground section, a common section, a first radiator, a second radiator, and a third radiator. The common section is electrically connected to the feed section, and the third radiator is electrically connected to the ground section. The first radiator, the second radiator, and the third radiator are all connected to the common section. The second radiator is spaced from the third radiator to allow current to be coupled from the second radiator to the third radiator. | 12-18-2014 |
20150022415 | ANTENNA STRUCTURE AND WIRELESS COMMUNICATION DEVICE EMPLOYING SAME - An antenna structure includes a main portion, a first radiating portion connected to the main portion, a second radiating portion connected to the main portion and opposite to the first radiating portion, and a coupling portion spaced from and coplanar with the main portion and opposite to the second radiating portion. The main portion and the first radiating portion excite a low frequency mode, the main portion, the first radiating portion, the second radiating portion, and the coupling portion excite a high frequency mode, and when the antenna structure is interfered by a user's human body when close to the user's human body, the coupling portion transmits the interference to ground. A wireless communication device employing the antenna structure is also disclosed. | 01-22-2015 |
