Abstract

An antenna structure may include a first radiation unit including a first radiator and a first transmission line that includes a first feeding portion directly connected to the first radiator and a first line portion connected to an end of the first feeding portion, a second radiation unit including a second radiator that has the same polarization direction as that of the first radiator, and a second transmission line that includes a second feeding portion directly connected to the second radiator and a second line portion connected to an end of the second feeding portion, and a third radiation unit including a third radiator that has the same polarization direction as that of the first radiator, and a third transmission line that includes a third feeding portion directly connected to the third radiator and a third line portion connected to an end of the third feeding portion.

Dependent claims

An antenna structure comprising:

a first radiation unit comprising a first radiator and a first transmission line, the first transmission line comprising a first feeding portion directly connected to the first radiator and a first line portion connected to an end of the first feeding portion;
a second radiation unit comprising a second radiator and a second transmission line, the second radiator having the same polarization direction as that of the first radiator, the second transmission line comprising a second feeding portion directly connected to the second radiator and a second line portion connected to an end of the second feeding portion;
and
a third radiation unit comprising a third radiator and a third transmission line, the third radiator having the same polarization direction as that of the first radiator, the third transmission line comprising a third feeding portion directly connected to the third radiator and a third line portion connected to an end of the third feeding portion,
wherein the first radiator and the second radiator are arranged along a first direction, and the second radiator and the third radiator are arranged along a second direction perpendicular to the first direction, and
two of the first line portion, the second line portion and the third line portion have different feeding directions.
