1. A multiband antenna, comprising:
a plurality of first radiator assemblies configured to radiate at a first frequency band; and
a plurality of second radiator assemblies configured to radiate at a second frequency band, wherein each of the plurality of second radiator assemblies is configured to radiate two orthogonally polarized radio frequency signals, wherein each second radiator assembly has a folded dipole, the folded dipole having a first pair of dipole arms configured to radiate in a first polarization orientation and a second pair of dipole arms configured to radiate in a second polarization orientation, wherein the folded dipole is formed of a single conductive plate that is disposed on a PCB (Printed Circuit Board).
