A repeater comprises a plurality of donor antennas and a plurality of service antennas. The repeater comprises a plurality of signal processing paths each comprising a first transceiver coupled to at least one of the donor antennas, a second transceiver coupled to at least one of the service antennas, and a digital signal processor coupled to the first and second transceivers. A controller is coupled to the plurality of signal processing paths. The controller is adapted to configure the repeater for a multiple-input-multiple-output (MIMO) operating mode and a carrier aggregation (CA) operating mode.

Antenna

A balance antenna is disclosed herein. The balanced antenna comprises a first planar conductor layer forming an first infinite balun, a second planar conductor layer forming a second infinite balun, and a feeding gap. A cable transports a radio signal from the antenna to a radio and from a radio to the antenna. The first infinite balun and the second infinite balun transform an unbalanced transmission line characteristic of the cable to the balanced feeding of the antenna.

Balanced antenna

There is disclosed an antenna system for mobile handsets and other devices. The antenna system comprises a dielectric substrate having first and second opposed surfaces, a conductive track on the substrate, and a separate, directly driven antenna to drive the parasitic loop antenna formed by the conductive track. Two grounding points are provided adjacent to each other on the first surface of the substrate, with the arms of the conductive track extending in generally opposite directions from the grounding points. The conductive tracks then extend towards an edge of the dielectric substrate, before passing to the second surface of the dielectric substrate and then passing across the second surface of the dielectric substrate following a path generally following the path taken on the first surface of the dielectric substrate. The conductive tracks then connect to respective sides of a conductive arrangement formed on the second surface of the dielectric substrate that extends into a central part of a loop formed by the conductive track on the second surface of the dielectric substrate.

Loop antenna for mobile handset and other applications

There is disclosed an antenna device made up of at least first, second and third conductive metal plates arranged in a parallelepiped configuration. The third plate defines a lower plane and the first and second plates together define an upper plane substantially parallel to the lower plane. The first and second plates are separated by a slot in the upper plane, and the second and third plates are connected to each other by a grounding connection. The first plate comprises a first, active antenna arm that is provided with a feed connection, and the second plate comprises a second antenna arm that may be passive or active. The antenna device generates a circularly polarized radiation pattern that is good for personal navigation devices, while being significantly more compact than existing ceramic patch antennas that are typically used in these devices.
