Assignee:

BlackBerry Limited - Waterloo, Ontario

International Classification:

H04M 1/00

US Classification:

4555757, 4555751, 3406935

Abstract:

A mobile wireless communications device may include a portable housing including at least one electrically conductive housing portion configured to function as an antenna. The mobile wireless communications device may also include a printed circuit board (PCB) carried by the portable housing, and wireless transceiver circuitry carried by the PCB and including at least one circuit element carried by the PCB. The mobile wireless communications device may also include at least one current shunt component coupled between the at least one electrically conductive housing portion and the at least one circuit element.

International Classification:

H01Q 1/24
H01P 11/00

US Classification:

343702, 29601

Abstract:

A mobile wireless communications device may include a portable housing that may include an electrically conductive continuous ring defining a perimeter of the portable housing. The electrically conductive continuous ring may be configured to function as an antenna. The mobile wireless communications device may further include a printed circuit board (PCB) carried by the portable housing and may include an electrically conductive layer defining a ground plane. The mobile wireless communications device may further include wireless transceiver circuitry carried by the PCB and coupled to the antenna. The mobile wireless communications device may also include an electrically conductive shorting member coupled between the electrically conductive continuous ring and the ground plane.

David FISK - Bedford TX, US
Seong Heon JEONG - Irving TX, US

International Classification:

H01Q 9/04

US Classification:

343700MS

Abstract:

A device having a coupled-feed wideband antenna is provided. The device comprises: a chassis comprising as a ground plane; an antenna feed, a ground side of the antenna feed connected to the ground plane; and, an antenna comprising: a first radiating arm configured for generating a first resonance at a first frequency, the first radiating arm connected to the chassis and hence the ground plane; a second radiating arm configured for generating a second resonance at a second frequency higher than the first frequency, the second radiating arm connected to the ground plane; and a third radiating arm configured for generating a third resonance at a third frequency higher than the second frequency, the first radiating arm capacitively coupled to the third radiating arm, and the third radiating arm connected to a positive side of the antenna feed.
