20100259454 | Mechanically tunable antenna for communication devices - A radio antenna assembly for use in a communication device has an antenna element disposed adjacent to a ground plane to form a physical relationship with the ground plane. A mechanical device is used to change the physical relationship for changing the operating impedance of the antenna element or shifting the frequency band of the antenna assembly. The physical relationship can be changed by mechanically changing the shape of the antenna element. When the antenna element comprises a first radiating element and a second radiating element disposed at a lateral distance from the first radiating element, the physical relationship can be changed by changing the distance. When a physical object is disposed between the antenna element and the ground plane, the physical relationship can be changed by moving or twisting the physical object. The object can be electrically conducting, dielectric or magnetic. | 2010-10-14 |
20100259455 | ANTENNA DEVICE AND PORTABLE RADIO COMMUNICATION DEVICE COMPRISING SUCH AN ANTENNA DEVICE - An antenna device for a portable radio communication device operable in at least a first and a second frequency band, includes first and second electrically conductive planar radiating elements. The first radiating element has a feeding portion connectable to a feed device of the portable radio communication device. The second radiating element includes a grounding portion connectable to ground. A controllable switch is arranged between the first and second radiating elements for selectively interconnecting and disconnecting the radiating elements. The state of the switch is controlled by means of a control voltage input. A first filter is arranged between the feeding portion and the control voltage input, to block radio frequency signals. By providing a high pass filter between the first and second radiating elements above a ground plane, quad-band operation is provided with high efficiency in a physically small antenna device. | 2010-10-14 |
20100259456 | MULTI-LAYER REACTIVELY LOADED ISOLATED MAGNETIC DIPOLE ANTENNAA - A multi-layer reactively loaded isolated magnetic (IMD) dipole with improved bandwidth and efficiency characteristics to be used in wireless communications and other applicable systems. The multi-layer IMD antenna comprises a first element positioned above a ground plane, a second element positioned above a ground plane and coupled to the first portion. Reactive components are integrated into one or both elements to optimize the frequency response of the antenna. The range of frequencies covered to be determined by the shape, size, and number of elements in the physical configuration of the components. Portions of or the entire ground plane can be removed beneath the elements. | 2010-10-14 |
20100259457 | MULTI-FREQUENCY, NOISE OPTIMIZED ACTIVE ANTENNA - A multi-frequency, noise optimized active antenna consisting of one or several actively tuned antennas optimized over incremental bandwidths and capable of tuning over a large total bandwidth. One or multiple impedance transformers are connected to the antennas at an optimal location, with the transformers acting to reduce the impedance for optimal coupling to a transceiver/receiver. Active components can be incorporated into the antenna structures to provide yet additional extension of the bandwidth along with increased optimization of antenna performance over the frequency range of the antenna. The radiating elements can be co-located with a ferrite material and/or active components coupled to the element to tune across a wide frequency range. | 2010-10-14 |
