20120231732 | HEARING DEVICE AND METHODS OF OPERATING A HEARING DEVICE - A hearing device is disclosed, in which antenna diversity is provided by means of including an antenna in each of two sub-units or earpieces, one being for each ear. The antennae communicate with a further communication device by conventional wireless RF transmission. The two sub-units communicate by means of near field communication, NFC. The two sub-units act in co-operation so as to ensure that a relatively higher quality baseband stream is extracted from either one or a combination of the receivers associated with the antennae. Deleterious effects from e.g. local disturbances to the electromagnetic field of the transmission may thereby be mitigated or overcome. | 09-13-2012 |
20130141297 | MULTI-BAND ANTENNA - The invention provides a multi-band antenna comprising a planar substrate which in use is intended for vertical mounting, and has a bottom edge and a top edge. A conductor pattern is printed on one side of the substrate with three slots. A first slot is a U or J shape facing downwardly and a second is a U or J shape facing upwardly. A third slot extends in the vertical direction and is open at the top. A first antenna feed is coupled to a horizontal track of the second slot and a second antenna feed is coupled to the third slot. The three slots together provide multi-band performance in three bands. | 06-06-2013 |

20150042524 | Antenna - An antenna comprises first and second conducting elements and first, second and third conducting lines. Each conducting element has a conductive surface. The first conducting line provides a short circuit between the conductive surfaces. The second conducting line has a first end electrically connected to one conductive surface and a second, free end. The third conducting line has a first end electrically connected to the other conductive surface and a second, free end. The second and third conducting lines are aligned along an axis X-X and each of the second ends of the second and third conducting lines serves as one of the terminals of a two terminal port F for feeding an RF signal of wavelength λ to the antenna. The first and second conducting elements are arranged with the conductive surfaces a face-to-face relationship, spaced apart by a distance d and the first, second and third conducting lines are arranged such that, when an RF signal is fed to the antenna, currents caused to flow in one conductive surface generate a magnetic field that at least partially cancels out the magnetic field generated by currents caused to flow in the other conductive surface and currents are caused to flow in the first, second and third conducting lines. | 02-12-2015 |
