Abstract
Various embodiments are directed to high isolation antenna design for reducing frequency coexistence interference. In one embodiment, a computing device may comprise a printed circuit board including a first internal antenna and a second internal antenna operating in a common frequency band. At least one of the first internal antenna and the second internal antenna may comprise a balanced antenna coupled to an unbalancing element to suppress surface current on the printed circuit board and reduce frequency coexistence interference between the first internal antenna and the second internal antenna. Other embodiments are described and claimed.
