This application provides an antenna structure and an electronic device including the antenna structure. The antenna structure includes a first radiator and a second radiator, and a first open end of the first radiator is opposite to and spaced from a second open end of the second radiator. A decoupling circuit is connected between the first open end and the second open end, so that isolation between a first antenna and a second antenna can be improved. The first radiator includes a first section and a second section that intersect, and the first section and the second section are respectively located on two adjacent sides of a ground, so that isolation between the first antenna and the second antenna can be further improved.
