1. An antenna, wherein the antenna operates in a target frequency band, a width of the target frequency band is greater than a preset threshold, the target frequency band comprises a first frequency and a second frequency, and the antenna is arranged on a metal substrate; and the antenna comprises a first radiation patch, a second radiation patch, a first short-circuit wall, and a second short-circuit wall, a projection of the first radiation patch and a projection of the second radiation patch on the metal substrate overlap, a projection of the first short-circuit wall on the metal substrate does not overlap with a projection of the second short-circuit wall on the metal substrate, the first short-circuit wall is located between the first radiation patch and the metal substrate, and is respectively connected to a first side of the first radiation patch and the metal substrate, the first side is a side of the first radiation patch perpendicular to a first radiation side, and the first radiation patch transmits a signal along the first radiation side, the second short-circuit wall is located between the first radiation patch and the second radiation patch, and is respectively connected to the first radiation patch and the second radiation patch, a resonant frequency of the first radiation patch is the first frequency, and a resonant frequency of the second radiation patch is the second frequency; and a projection of the first radiation side of the first radiation patch on the metal substrate overlaps with a projection of a second radiation side on the metal substrate on the second radiation patch, and the second radiation patch transmits a signal along the second radiation side,
wherein the antenna further comprises a first structural body, and the first structural body is configured to adjust impedance of the first radiation patch; and/or the antenna further comprises a second structural body, and the second structural body is configured to adjust impedance of the second radiation patch.
