Claim Text:
1. An antenna structure comprising: a group of dipole radiating elements joined by two continuous zigzag feed lines positioned such that one group of the radiating elements located on a top surface of a circuit board is fed by one zigzag feed line and the opposing group of radiating elements on the bottom surface of the circuit board is fed by the other zigzag feed line, characterized in that the radiating structure forms a collinear array with the feed lines arranged in half wavelength segments in zigzag positions along the center of the horizontal line of the dipole elements such that each half wavelength segment of the top feed line crosses the center of the corresponding half wavelength segment of the bottom feed line, and the crossing points are electrically joined symmetrically away from the center dipole element to control the radiation of the antenna structure selectively; the antenna structure is symmetrically fed from the center; and the dipoles are equal in length and are equally spaced.
