1. A multi-band shark fin antenna, comprising:
a base;
a substrate coupled to an upper portion of the base and on which feed lines are formed; and
a first antenna frame coupled on the substrate and to which a plurality of radiators are coupled, wherein the first antenna frame comprises:
a first radiator coupling part to which a first radiator is coupled; and
a first support extending from the first radiator coupling part and supporting the first radiator coupling part,
wherein an antenna coil is coupled to an outer circumferential surface of the first support, and the antenna coil is electrically connected to the first radiator,
wherein the antenna coil includes a coil part, an upwardly extending part extending vertically from the coil part in an upward direction, and a downwardly extending part extending vertically from the coil part in a downward direction, and
wherein a hole is formed in the first radiator coupling part, the upwardly extending part passes through the hole and protrudes above the first radiator coupling part, and the protruding upwardly extending part is coupled to the first radiator through soldering.
