Antenna assembly and electronic device

An electronic device, comprising:

• a circuit board;
• and
• an antenna assembly, comprising:
• a first antenna comprising a first radiator, a first signal source, and a first matching circuit, wherein the first radiator has a first feed point, and the first signal source is electrically connected to the first feed point through the first matching circuit;
• and
• a second antenna comprising a second radiator, a third radiator, a second signal source and a second matching circuit, wherein the second radiator and the first radiator are spaced apart from each other and coupled to each other, the second radiator has a second feed point, the second signal source is electrically connected to the second feed point through the second matching circuit, the second signal source is electrically connected to the third radiator through the second matching circuit, and the first antenna and the second antenna jointly act to transmit and receive electromagnetic wave signals in at least one of a first frequency band range, a second frequency band range and a third frequency band range;
• wherein one or more of the first signal source, the second signal source, the first matching circuit, and the second matching circuit is provided on the circuit board.
