Abstract
A dual polarization base station antenna producing a beam having 3 dB azimuth beamwidth of E(theta) within 5° of the 3 dB azimuth beamwidth of E(phi). The antenna also maintains E(theta) and E(phi) within 3 dB of each other over a wide beamwidth up to 120°, and over a wide bandwidth of 30% of the center frequency. The antenna achieves these performance characteristics through beam shaping structures connected to or located near the ground plane supporting the dipole antenna elements. By adjusting the locations and shapes of the beam shaping structures, specific antennas are designed to meet these design characteristics for different desired beamwidths, including 45°, 60°, 90° and 120°.
