Classification: CPC H | IPC H

Claim 0:
1. An antenna comprising:
a radiation conductor;
a ground conductor;
a first feeding line that is configured to be electromagnetically connected to the radiation conductor;
a second feeding line that is configured to be electromagnetically connected to the radiation conductor;
a third feeding line that is configured to be electromagnetically connected to the radiation conductor;
a fourth feeding line that is configured to be electromagnetically connected to the radiation conductor;
a first feeding circuit that is configured to feed reversed-phased signals, which have mutually opposite phases, to the first feeding line and the third feeding line; and
a second feeding circuit that is configured to feed reversed-phased signals, which have mutually opposite phases, to the second feeding line and the fourth feeding line, wherein
the radiation conductor is configured to be excited in a first direction due to feed from the first feeding line and the third feeding line,
the radiation conductor is configured to be excited in a second direction due to feed from the second feeding line and the fourth feeding line,
when seen from a center of the radiation conductor, the third feeding line is positioned on opposite side of the first feeding line in the first direction, and
when seen from a center of the radiation conductor, the fourth feeding line is positioned on opposite side of the second feeding line in the second direction.
