Abstract

The invention provides electronic equipment. The electronic device includes a housing and an antenna structure within the housing. The antenna structure comprises a circuit board and a first radiation structure. The first radiation structure comprises a first radiation ring and a plurality of branches. An included angle is formed between the axial direction of the first radiation ring and the circuit board. The shell comprises a metal ring shell body, the metal ring shell body extends in the axial direction, and the axial direction is parallel to the axial direction of the first radiation ring. The plurality of branches are distributed along the circumferential direction of the first radiation ring and are connected between the first radiation ring and the circuit board, and specifically comprise a feed branch and at least two first grounding branches. The branch knots are electrically connected with the circuit board, and two adjacent branch knots and a first section, located between the two branch knots, of the first radiation ring form an antenna substructure. The feed branch knot is used for feeding the first radiation ring, the first radiation structure is used for first resonance, and the first radiation structure can be equivalent to a plurality of connected antenna substructures, so that a high-efficiency omnidirectional radiation mode of the antenna structure is realized.
