Abstract
Disclosed is an antenna that enables dense packing of low band, mid band, and C-band radiators. The low band radiators have a plurality of dipole arms that minimize re-radiation of either RF energy emitted by either the mid band or C-Band radiators. In one embodiment, the dipole arms are formed of a two-dimensional structure that has a shape that substantially prevents re-radiation in both the mid band and the C-band. In another embodiment, the dipole arms have two different configurations: a first configuration optimized for preventing re-radiation in the mid band, and a second configuration optimized for preventing re-radiation in the C-Band. In the latter embodiment, the low band radiators in close proximity to the mid band radiators have dipole arms of the first configuration, and the low band radiators in close proximity to the C-Band radiators have dipole arms of the second configuration.
