As shown in fig. 1-2, the present invention provides an antenna, which includes a metal housing 1, a first circuit board 2, and a first connecting rib 3. A part of the metal housing 1 may be used as a radiator of the antenna, and the first circuit board 2 is provided with a feeding point S21 and a matching circuit, through which a frequency band of the antenna may be matched, so that the antenna receives electromagnetic wave signals in the frequency band.
In the invention, the first circuit board 2 comprises a first floor layer, a first broken seam 21 is arranged on the first circuit board 2, and the first broken seam 21 penetrates through the first floor layer. The metal shell 1 is provided with a first gap 11 and a second gap 12, the metal shell forms a three-section structure by the first gap 11 and the second gap 12, the three-section structure comprises a first shell 1a, a middle shell 1b and a second shell 1c which are sequentially arranged, and the middle shell 1b is electrically connected with the first floor layer so that the middle shell 1b forms a system ground. In the embodiment shown in fig. 1, the middle housing 1b is electrically connected at D10 to the first floor layer at D20 by a metal spring finger.
The first connecting rib 3 is disposed at the first gap 11, and the first housing 1a is electrically connected to the middle housing 1b through the first connecting rib 3, that is, the position of the first connecting rib 3 on the first housing 1a is a grounding point on the first housing 1 a.

According to the above description, the opening of the first broken seam 21 allows a part of the first floor layer on the first circuit board 2 to be removed, thereby reducing the area of the first floor layer that blocks the radiation of the antenna and increasing the clearance of the antenna so that the feeding point S21 on the first circuit board 2 is located at the clearance of the antenna. Meanwhile, the first broken seam 21 on the first circuit board 2 becomes a part of the antenna, when an electromagnetic wave signal is transmitted and received, a resonant frequency is generated when the electromagnetic wave passes through the first broken seam 21, so that the frequency band of the antenna is widened, the multi-band coverage of the antenna is realized, and the performance of the antenna is improved.
It should be noted that the phrase "the length dimension of the first slit segment 11a is equal to the length dimension of the first broken slit 21" means that the length dimensions are substantially equal, that is, the length dimension of the first slit segment 11a and the length dimension of the first broken slit 21 are allowed to have a small deviation, and a person skilled in the art can control the deviation within a reasonable range according to experience.
The number of the first broken joints 21 and the number of the first slit segments 11a may be one or more, but the present invention is not limited thereto, and when the number of the first broken joints 21 and the number of the first slit segments 11a are more than one, each of the first broken joints 21 is directly opposite to each of the first slit segments 11 a.
