Abstract

A device includes a plurality of antennas, including one or more active antennas, the antennas being configured in one of a plurality of possible configurations to achieve operation in WAN, LTE, WiFi, or WiMax bands, or a combination thereof. In some embodiments, a passive antenna is utilized with lumped loading to fix the antenna tuning state. A primary and auxiliary radiator can be included in the device and configured for WAN/LTE bands, while additional antennas can be incorporated for WiFi and WiMax bands. Various antenna configurations incorporate the antenna having multiple coupled regions.

Claims19

Dependent claims

A portable wireless communication device, comprising:

a display screen;
and
an antenna system comprising at least a first antenna having multiple coupled regions and a second antenna having multiple coupled regions, the first antenna comprising:
a ground plane;
a transceiver;
a tunable component connected to the ground plane;
a first antenna element positioned above the ground plane and connected to the transceiver;
a second antenna element positioned above the ground plane and connected to the ground plane, the second antenna element being capacitively coupled to the first antenna element to form a first coupling region;
and
a third antenna element positioned above the ground plane and connected to the tunable component, the third antenna element being capacitively coupled to the second antenna element to form a second coupling region.
