Abstract

Embodiments of the present disclosure disclose an antenna, and relate to the field of wireless communications. In the antenna, radiation parts of the antenna are disposed on at least two layers of circuit boards on a printed circuit board: a top layer circuit board and a first layer circuit board, so that lengths of the radiation parts of the antenna are reduced, and space occupied by a printed wire of the antenna on the PCB is reduced. Therefore, reducing a PCB size becomes possible, a size of a terminal using the reduced-size PCB may also be correspondingly reduced, and the terminal may be further miniaturized.

Dependent claims

An antenna comprising:

a top layer circuit board;
a first layer circuit board;
a first radiation part;
a second radiation part;
and
a feed, wherein the first radiation part and the feed are printed in a cabling region of the top layer circuit board, wherein an end of the first radiation part is connected to a first side of a first copper foil region of the top layer circuit board, wherein the feed is located between the first radiation part and a second side of the first copper foil region, wherein a gap is formed between the feed and the first copper foil region, wherein the feed is not in contact with the first radiation part and is connected to a signal cable, wherein the second side of the first copper foil region is vertical to either of the first side and a third side of the first copper foil region and the first side of the first copper foil region is opposite the third side of the first copper foil region, wherein the second radiation part is printed in a cabling region of the first layer circuit board and an end of the second radiation part is connected to a third side of a second copper foil region of the first layer circuit board and partially overlaps with the first radiation part, and wherein a lower surface of the top layer circuit board fits an upper surface of the first layer circuit board.
