1. An antenna, comprising:
a first antenna segment and a second antenna segment that are sequentially connected and disposed in a length direction of the antenna,
wherein the antenna is for a foldable electronic device, the foldable electronic device comprises a first housing and a second housing, the first housing and the second housing are rotatably connected to each other by using a rotating shaft located between the first housing and the second housing so that the foldable electronic device switches between an unfolded state and a folded state, the first housing is of a first side on which a display screen of the foldable electronic device is located, the second housing is of a second side on which a keyboard of the foldable electronic device is located, the antenna is disposed in a space formed by a region surrounded by the first housing, the second housing, and the rotating shaft, and, when the foldable electronic device is in the unfolded state, an opening/closing region is formed between the first housing and the second housing
wherein the first antenna segment includes a first end and a second end, the first end of the first antenna segment is connected to a ground plate of the first housing, and the first antenna segment extends toward the opening/closing region, from the first end of the first antenna segment to the second end of the first antenna segment; and
the second antenna segment includes a third end and a fourth end, the third end of the second antenna segment is connected to the second end of the first antenna segment so that the second antenna segment, at the third end of the second antenna segment, is disposed at an angle to the first antenna segment at the second end of the first antenna segment, the fourth end of the second antenna segment is spaced apart from the ground plate of the first housing, the first antenna segment is entirely disposed away from a lower edge of the first housing relative to the second antenna segment entirely, the second antenna segment further comprises a feed part, and a radio frequency module of the foldable electronic device performs feeding on the feed part of the second antenna segment by using a feed line directly or by means of coupled feeding.
