A wireless device including multiple counterpoises or ground planes is provided. The wireless device may provide improved multiple input multiple output (MIMO) communication capability through the use of the multiple counterpoises. Multiple counterpoises of the wireless device may be galvanically isolated from one another. Multiple counterpoises may each be coupled to separate antenna elements.

Isolated ground for wireless device antenna

A multi-feed antenna assembly including a ground element lying in a plane, a first antenna element coupled to the ground element and having a projection on the plane, a first feed for feeding the first antenna element, a second antenna element coupled to the ground element and having a projection on the plane, the projection of the second antenna element being at least partially encompassed by the projection of the first antenna element and a second feed for feeding the second antenna element.

Multi-feed antenna assembly

A antenna for a wireless device is provided. The antenna may include a dielectric substrate, a counterpoise disposed on the dielectric substrate, a first conductive element electrically connected to the counterpoise, and a second conductive element electrically connected to a feed point. The first conductive element may form at least a portion of a radiating loop resonant at a first frequency, and the second conductive element may form at least a portion of a radiating spur resonant at a second frequency higher than the first frequency. The antenna may further include a conductive frame constituting at least a portion of the radiating loop or the radiating spur.

Conductive loop antennas

A dual branch antenna is provided. The dual branch antenna may include a continuous conductive element divided into first and second branches. Each branch may be configured to form at least a portion of an antenna structure. Antenna structures thus formed may be configured to radiate in at least two different frequencies.
