Abstract
An antenna of the present invention includes an electrical half wave monopole antenna element fixedly attached to a surface, where the antenna element includes an electrical center. A first electrical feed point is located on a first side of the antenna element. A second electrical feed point is located on a second side of the antenna element. The second side generally opposes the first side of the antenna element. The first and second electrical feed points are about one-twentieth a wavelength from the electrical center. A first signal corresponds with the first electrical feed point and a second signal corresponds with the second electrical feed point. The first signal is out of phase when compared to the second signal.
