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.

Antenna with multiple coupled regions

A hybrid antenna and integrated proximity sensor is described wherein a commonly shared conductive structure is used for both antenna functions as well as a proximity sensor functions.

Hybrid antenna and integrated proximity sensor using a shared conductive structure

An antenna having a driven element coupled to multiple additional elements to resonate at multiple frequencies. A magnetic dipole mode is generated by coupling a driven element to a second element, and additional resonances are generated by coupling additional elements to either or both of the driven or second element. One or multiple active components can be coupled to one or more of the coupled elements to provide dynamic tuning of the coupled or driven elements.

An antenna ground structure, for use in an electronic apparatus includes an antenna main body and electrically conductive plastic material connecting the antenna main body is a metal frame of the electronic apparatus to provide an electrical connection between the antenna main body and the metal frame. Better electrical characteristics can be provided to the antenna main body through the antenna ground structure. The manufacturing process is further improved.

Antenna ground structure

A multi-band antenna structure includes a ground plane, a first radiation metal arm, a first shorted parasitic arm and a second shorted parasitic arm. The first radiation metal arm is connected to a main transmitting antenna and has a first feed point for connecting a first feed line. The first shorted parasitic arm extends to the outside from the ground plane. The first shorted parasitic arm is between the first radiation metal arm and the ground plane for resonantly coupling the first radiation metal arm at a first band. The second shorted parasitic arm also extends to the outside from the ground plane. The second shorted parasitic arm is between the first radiation metal arm and the first shorted parasitic arm for resonantly coupling the first radiation metal arm at a second band.
