1. A multiband antenna, comprising:
a plurality of first dipoles configured to radiate in a first frequency band; and
one or more second dipoles configured to radiate in a second frequency band,
wherein each of the first dipoles has a radiator plate and a balun stem, each radiator plate having a first side and a second side opposite the first side, a capacitive coupling element disposed on the first side, and a folded dipole element disposed on the second side,
wherein the capacitive coupling element has an inductive trace that electrically couples to a radiator inductive trace through a via formed in the radiator plate, the radiator inductive trace coupled to the folded dipole element.
