1. A multiband antenna, comprising:
a reflector plate;
a plurality of high band dipoles configured to radiate RF energy in a high band; and
a plurality of low band dipoles configured to radiate RF energy in a low band,
wherein each of the low band dipoles has a plurality of low band dipole arms, each low band dipole arm being formed of a single piece of metal, the single piece of metal having a plurality of inductor structures, the inductor structures each having a dimension that makes the inductor structure hinder the low band dipole from re-radiating RF energy in the high band, and that enables the inductor structure to radiate RF energy in the low band.
