Linearly-polarized dual-band base-station antenna

摘要

A dual-band antenna suitable for use in a cellular telephone network base station includes two parallel arrays of low-frequency dipole elements disposed on a ground plane, a raised array of high-frequency dipole elements disposed between the two parallel arrays, and at least one beamforming rod disposed between the raised array and the two parallel arrays. The two parallel arrays operatively form symmetric azimuth radiation patterns in a lower range of frequencies. The raised array and the high frequency beamforming rod likewise operatively form symmetric azimuth radiation patterns in a higher range of frequencies. This configuration of dual-band antenna allows reception and transmission of electromagnetic signals in two discrete frequency bands while occupying a compact space.
