Abstract
A wideband antenna system with multiple antennas and at least one parasitic element is disclosed. In an exemplary design, an apparatus includes a first antenna, a second antenna, and a parasitic element. The first antenna has a shape of an open-ended loop with two ends that overlap and are separated by a gap. The second antenna may also have a shape of an open-ended loop with two ends that overlap and are separated by a gap. The parasitic element is located between the first and second antennas. The first and second antennas may be placed side by side on a board, located at either the top end or the bottom end of a wireless device, and/or formed on opposite sides (e.g., the front and back sides) of the board. The parasitic element may be formed on a plane that is perpendicular to the plane on which the first and second antennas are formed.
