| 1. A multiband antenna system comprising:
a substrate;
an antenna which is disposed on a first side and a second side of the substrate, and produces a resonance in a plurality of
frequency bands;
a plurality of feeders which are disposed on the first side of the substrate; and
a filter which is disposed on the first side of the substrate, is coupled to an end of the antenna, and transfers signals
in the plurality of frequency bands to respective feeders of the plurality of the feeders,
wherein the antenna comprises:
a first radiator which is disposed on the first side of the substrate, wherein a first end of the first radiator is coupled
to the filter; and
a second radiator which is disposed on the second side of the substrate, wherein a first end of the second radiator is coupled
to a second end of the first radiator through a via hole, and a second end of the second radiator is opened.
