Dual polarized omni-directional antenna and base station including same

A dual polarized omni-directional antenna, comprising:

• a plurality of radiating elements disposed to be spaced apart in one direction;
• and
• a feed line for providing a feed signal to the plurality of radiating elements,
• wherein the plurality of radiating elements comprise a first radiator for generating one polarization of dual polarization, and a second radiator for generating the other polarization of the dual polarization, respectively,
• wherein the first radiator is prepared on a first surface, and the second radiator is prepared on a second surface, and
• wherein a main lobe direction of the first radiator and a main lobe direction of the second radiator are different directions from each other,
• wherein the dual polarized omni-directional antenna further comprises a feed plate on which a feed pattern has been formed so as to feed the first radiator and the second radiator, respectively, and
• wherein the feed plate comprises:
• a support layer having the feed pattern formed on an upper surface thereof;
• and
• a ground layer formed on a lower surface of the support layer, and on which a ground pattern has been formed,
• wherein an inner conductor of the feed lime penetrates the feed plate td be electrically connected with the feed pattern, and
• wherein an outer conductor of the feed line is electrically connected with the ground pattern.
