Abstract:
A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device.
Abstract:
An apparatus including an antenna; a first part including a first ground plane portion; a second part including a second ground plane portion; a first electrical connection between the first part and the second part; and a second electrical connection between the first ground plane portion and the second ground plane portion that includes a reactive component.
Abstract:
An apparatus including a radiator having an electrical length; a first conductive element; an interconnector, connected to the radiator and to the first conductive element, having a first configuration and a second configuration, wherein the radiator has a first electrical length when the interconnector is in the first configuration and a second electrical length, different to the first electrical length, when the interconnector is in the second configuration.

Abstract:
An antenna having a plurality of resonant frequencies and including a ground plane having an edge; a feed point; a ground point; and an antenna track extending between the feed point and the ground point and comprising, in series connection, a first loop and a second loop wherein a least a portion of the first loop and a portion of the second loop are adjacent at least the edge of the ground plane.
Abstract:
The invention relates to a radio antenna and, more specifically, to an internal multiband antenna for use e.g. in a portable telecommunication device, such as a mobile phone. In particularly the invention relates to an antenna module for a mobile terminal comprising including a non-resonant antenna element, two resonant antenna elements each covering at least any one of a first, second, third or fourth frequency band, said two resonant elements are substantially in the same plane and define a planar surface wherein the two resonant elements are each positioned at a corner of the planar surface and the non-resonant element is positioned along an edge of the planar surface.
Abstract:
The specification and drawings present a new apparatus, method and software product for using a cover antenna (e.g., conductive, metallic, etc.) in an electronic device, with multiple coupled feeds (e.g., dual feed) to the antenna and with one or more switches and a matching circuit. Then it is possible to use a metal plate as a metal cover, e.g., for mobile devices, which will act as an antenna with multiple feedings for cellular and non-cellular radios.
