A dual strip antenna that includes first and second conductive strips, each made from a conductive material. The first and second strips are separated by a dielectric substrate having a predetermined thickness. The first strip is electrically connected to the second strip at one end. A coaxial signal feed is coupled to the dual strip antenna. The dual strip antenna provides an increase in bandwidth over conventional microstrip patch antennas, which is made possible by operating the dual strip antenna as an open-ended parallel plate waveguide having asymmetrical conductor terminations. The operation of the dual strip antenna as an open-ended parallel plate waveguide is achieved by selecting appropriate dimensions for the lengths and widths of the first and second strips. Antenna compactness and a greater variety of useful shapes allow the dual strip antenna to be used as an internal wireless device antenna.
