Abstract

Various embodiments of an internal diversity antenna architecture are described. In one embodiment, a wireless device may include a housing enclosing a printed circuit board, a first diversity antenna, and a second diversity antenna internal to the housing. The second diversity antenna may be positioned substantially near the bottom of the housing or the bottom the printed circuit board. Other embodiments are described and claimed.
