1. An antenna, comprising:
a radiating element comprising a first radiator and a second radiator, wherein the first radiator comprises a first radiating arm and a second radiating arm, the second radiator comprises a third radiating arm and a fourth radiating arm, the first radiating arm extends in a first direction on a first plane and the second radiating arm extends in a second direction on the first plane, the second direction being an opposite direction to the first direction, the third radiating arm extends in a third direction on a second plane and the fourth radiating arm extends in a fourth direction on the second plane, the fourth direction being an opposite direction to the third direction, the second plane is spaced apart from and parallel with the first plane, and the first direction is perpendicular to the third direction;
a first feed line configured to transmit a first feed signal to the first radiating arm and the second radiating arm;
a second feed line configured to transmit a second feed signal to the third radiating arm and the fourth radiating arm; and
a feed plate comprising a first feed pattern and a second feed pattern formed on its upper surface and a ground pattern on its lower surface, wherein the first feed pattern is configured to provide the first feed signal to the first radiating arm and the second radiating arm, and the second feed pattern is configured to provide the second feed signal to the third radiating arm and the fourth radiating arm,
wherein the first feed line comprises an inner conductor and an outer conductor,
wherein the first feed line penetrates the feed plate so that the inner conductor of the first feed line is in contact with the first feed pattern and the outer conductor of the first feed line is in contact with the ground pattern.
