Abstract
An omni-directional small cell base station antenna includes at least one array of a first frequency on a lower portion of the antenna, at least one second array of a second frequency on an upper portion of the antenna, and at least one third array of a third frequency on the upper portion of the antenna. The second frequency is higher than the first frequency, and the third frequency is higher than the second frequency. The at least one second array at a second frequency includes a plurality of reflector plates with antenna elements of the second frequency thereon, and the at least one third array at a third frequency includes a plurality of reflector plates with antenna elements of the third frequency thereon. The reflector plates of the at least one second array are interspersed between the reflector plates of the at least one third array such that the reflector plates of the second and third arrays alternate around the circumference of the upper portion of the antenna.
