Small cell antenna assembly and module for same
An antenna assembly includes: a plurality of antenna-radio units, each of the antenna-radio units comprising an antenna and a radio transceiver in an integrated unit, each antenna having an external face; and a mounting assembly comprising a foundation, a cap and a spine, the foundation being mounted to a lower end of the spine and the cap mounted to an upper end of the spine. The antenna-radio units are mounted at circumferentially equally spaced locations between the foundation and the cap, with their respective external faces facing radially outwardly. The assembly also includes a plurality of spacers, each spacer located between two adjacent antenna-radio units, and each antenna-radio unit between located between two adjacent spacers, each of the spacers including an arcuate external surface. The external faces of the antennas and the external surfaces of the spacers generally define a cylinder.
1. An antenna assembly, comprising:
a plurality of antenna-radio units, each of the antenna-radio units comprising an antenna and a radio transceiver combined in an integrated unit residing within a single housing, each antenna having an external face;
a mounting assembly comprising a foundation, a cap and a single elongate tubular member extending between a center of the foundation and a center of the cap to form a spine of the mounting assembly, the foundation being mounted to a lower end of the spine and the cap mounted to an upper end of the spine;
wherein the antenna-radio units are mounted to the spine at circumferentially equally spaced locations between the foundation and the cap, with their respective external faces facing radially outwardly.
