1. An antenna unit, comprising:
a first loop branch, a first feed, and a second feed,
wherein the first loop branch comprises a first radiation section, a second radiation section, and a third radiation section,
wherein the first radiation section is in a ring shape, and the first radiation section is not closed, a first end of the first radiation section is connected to the second radiation section, and a second end of the first radiation section is connected to the third radiation section,
wherein the second radiation section and the third radiation section are symmetrically disposed in a first direction, there is an opening between the second radiation section and the third radiation section, and both the second radiation section and the third radiation section are grounded,
wherein the first feed is symmetrically connected to the first radiation section in the first direction, and
wherein a second contact point and a third contact point are symmetrical in the first direction, a distance between the second contact point and the third contact point falls within a first preset range, the second contact point is between the second feed and the second radiation section, and the third contact point is between the second feed and the third radiation section.
