ABSTRACT:
The present invention relates generally to the field on antennas and more specifically, to a low profile horizontally polarized sector antenna. The antenna includes a printed circuit board that has a dielectric substrate provided with a pair of first and second opposed faces and at least one dipole element formed on the dielectric substrate. The at least one dipole element has a pair of first and second, oppositely extending, dipole arms. The first dipole arm is formed on the first face of the dielectric substrate and the second dipole arm is formed on the second face thereof. The at least one dipole element has a width W corresponding to the span between the first and second dipole arms. The printed circuit board is also provided with a feed network that is operatively connected to the at least one dipole element. The antenna further includes a pair of conductive boards mounted to the dielectric substrate to stand proud of the second face thereof. The conductive boards are spaced from each other a distance D. The distance D is greater than the width W. The distance D is selected to obtain an E-Plane beamwidth for the antenna ranging from about 90 degrees to about 240 degrees. The antenna also has a ground plane that is operatively connected to the pair of conductive boards.
