Abstract
A multi-band antenna array for use in wireless communication devices with up to three simultaneous operating modes with improved antenna efficiency and reduced antenna coupling across a broad range of operative frequency bands with reduced physical size is described. The multi-band antenna array includes at least two loop antenna elements, each of which is orthogonal to, and arranged in an embedded manner, relative to each other. Each loop antenna in the multi-band antenna array may include a corresponding tuning element for tuning to a desired resonant frequency, and be comprised of an upper and lower half with the corresponding tuning element coupled therebetween.

A wireless device for cellular communications, comprising:
- a multi-band antenna characterized by three loop antenna elements, each of the three loop elements having different size from one another and arranged to loop orthogonally relative to and within one another;
- and
- three tuning elements each associated with a respective one of the three loop antenna elements,
- where the tuning elements selectively tune each of the loop antenna elements to resonate at different frequencies simultaneously, as well as tune to different frequencies when switching from receive and transmit modes of operation,
- wherein the selectively tuning by the tuning elements is such as to minimize the size of the three loop antenna elements to allow for a small form factor of the cellular communication device.
