Abstract:
A multiband antenna for a mobile device is disclosed. The mobile device includes a multiband antenna configured to communicate with a base station. The multiband antenna includes a ground plane (102), a ground plane extension (106), and a plurality of antenna arms(114, 116, 118). The ground plane, the ground plane extension, and the plurality of antenna arms are configured to communicate signals in multiple frequency bands, where the ground plane and the ground plane extension have a length proportional to approximately a quarter wavelength of a frequency in the multiple frequency bands. The mobile device further includes a modulator and demodulator configured to modulate signal for transmission and demodulate signal received from the base station, and a controller configured to control communication of signals using the multiband antenna and the modem.
Abstract:
Exemplary embodiments are directed to an antenna device. A device may include an antenna element including a first electrically conductive element oriented in a first direction and a second electrically conductive element oriented in a second, different direction, the first and second conductive elements being electrically connected at one respective end. The device may further include a matching circuit operably coupled to the antenna element. The device may further include a wearable structure (404) having each of the antenna element and the matching circuit integrated therein.
Abstract:
A wireless communication device is provided with a multipart case, having electrical interfaces that encourage the flow of radiation frequency ground current between case sections. The multipart case has a first planar groundplane section and a second planar groundplane section. For example, the multipart case design may be a slider, double slider, multiple hinge, flip, or swivel case. The second planar groundplane is substantially coplanar with the first groundplane in a case open position, and substantially bi-planar with the first groundplane in a case closed position. The wireless device also includes an antenna located adjacent the second groundplane section first end. A first and a second interface electrically connect the first groundplane section to the second groundplane section second end (the end opposite the antenna).

A multiband antenna for a mobile device is disclosed. The multiband antenna includes a plurality of flexible antenna arms (114,116,118) configured to. communicate signals in multiple frequency bands, a flexible antenna counterpoise, (102,106) a battery configured to provide power to the multiband antenna, and control logic configured to control communication of signals of the multiband antenna, where the plurality of flexible antenna arms, the flexible antenna counterpoise, the battery, and the control logic are bonded to a flexible insulation material. The multiband antenna further includes at least a portion of circuit schematics that connect the plurality of flexible antenna arms, the flexible antenna counterpoise, the battery and the control logic are placed and routed on the flexible insulation material.
Abstract:
The invention utilizes small, narrow-band and frequency adaptable antennas to provide coverage to a wide range of wireless modes and frequency bands on a host wireless device. The antennas have narrow pass-band characteristics, require minimal space on the host device, and allow for smaller form factor. The frequency tunability further allows for a fewer number of antennas to be used. The operation of the antennas may also be adaptably relocated from unused modes to in-use modes to maximize performance. These features of the antennas result in cost and size reductions. In another aspect, the antennas may be broadband antennas.
