20100277390 | MULTIBAND ANTENNA - A multiband antenna includes a first antenna unit and a second antenna unit. The first antenna unit includes a first radio member and a second radio member connected to the first radio member. The second antenna unit includes a third radio member and a fourth radio member connected to the third radio member. The first antenna unit receives/sends wireless signals at relatively higher frequencies; the second antenna unit receives/sends wireless signals at relatively lower frequencies. | 11-04-2010 |
20100309067 | MULTIBAND ANTENNA - A multiband antenna includes a first radio unit closed loop and a second radio unit connected to the first radio unit and symmetrical structure. When the multiband antenna functions, the first radio unit functions as a balanced loop antenna, and the second radio unit functions as a dipole antenna. | 12-09-2010 |
20110001675 | ANTENNA OF PORTABLE ELECTRONIC DEVICES - An antenna used in portable electronic devices includes a first antenna unit shaped as a planar inverted-F antenna (PIFA) and a second antenna unit shaped as a loop antenna and connected to the first antenna unit. The first antenna unit receives/sends wireless signals at relatively higher frequencies, the second antenna unit receives/sends wireless signals at relatively lower frequencies, and the first antenna unit is coupled with the second antenna unit to regulate the working frequency band of the antenna. | 01-06-2011 |
20120162017 | MULTIBAND ANTENNA - A multiband antenna includes a feed unit, a first radio unit, a second radio unit, and a resonance unit. When feed signals are input from the feed unit, the feed signals are respectively transmitted to the first radio unit and the second radio unit to enable the first radio unit and the second radio unit to respectively receive and send wireless signals of different frequencies, and the resonance unit is driven to resonate and is thereby enabled to receive and send wireless signals of predetermined frequencies, such that the multiband antenna is capable of receiving and sending wireless signals in more than two frequency bands. | 06-28-2012 |
20120162038 | MULTIBAND ANTENNA - A multiband antenna includes a feed unit, a transceiving unit, and a resonance unit positioned adjacent to but separate from the feed unit and the transceiving unit. When feed signals are input to the feed unit, the feed signals are transmitted to the transceiving unit to form current paths of different lengths, and the resonance unit is driven to resonate and generates additional current paths of different lengths. In this way, the transceiving unit and the resonance unit are enabled to respectively receive and send wireless signals of different frequencies, and thus the multiband antenna is capable of receiving and sending wireless signals in more than two frequency bands. | 06-28-2012 |
20120162043 | MULTIBAND ANTENNA - A multiband antenna includes a feed unit, a first transceiving unit, a second transceiving unit, and a resonance unit. The first transceiving unit and the second transceiving unit cooperatively form a loop. When feed signals are input to the feed unit, the feed signals are respectively transmitted through the first transceiving unit and the second transceiving unit to enable the first transceiving unit and the second transceiving unit to respectively receive and send wireless signals of different frequencies, and the resonance unit is driven to resonate and cooperate with the first transceiving unit and the second transceiving unit to respectively form additional antenna members, such that the multiband antenna is capable of receiving and sending wireless signals in more than two frequency bands. | 06-28-2012 |
20120262342 | MULTIBAND ANTENNA - A multiband antenna includes a feed unit, a ground unit, a first radiator unit, a second radiator unit, a first resonance unit, and a second resonance unit. When feed signals are input to the feed unit, the feed signals are transmitted to the first radiator unit and the second radiator to form current paths of different lengths, and the first resonance unit and the second resonance unit are driven to resonate and respectively generate additional current paths of different lengths. In this way, the first radiator unit, the second radiator unit, the first resonance unit, and the second resonance unit are enabled to receive and send wireless signals of different frequencies. | 10-18-2012 |
20120274538 | MULTIBAND ANTENNA AND WIRELESS COMMUNICATION DEVICE EMPLOYING THE SAME - A multiband antenna in a wireless communication device includes a main antenna, a first parasitic portion, a second parasitic portion, a first switch, and a second switch, the first switch is used to control functioning of the first parasitic portion. The second switch is used to control functioning of the second parasitic portion. Therefore, the main antenna can resonate alone or in combination with the functioning first parasitic portion and/or the functioning second parasitic portion, the multiband antenna has different operating frequency bands and different operating SAR. | 11-01-2012 |
