Abstract
An 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. 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.
