Antenna assembly and electronic device

An antenna assembly, comprising:

• a first antenna comprising a first radiator and a first feed source, wherein the first feed source is connected to a first feed point of the first radiator, and the first radiator is configured to support a first frequency band and a second frequency band under a first excitation signal generated by the first feed source;
• a second antenna comprising a second radiator and a second feed source, wherein there is a first gap between a first terminal of the second radiator and the first radiator, and the second radiator is capable of being coupled with the first radiator through the first gap;
• the second radiator is provided with a second feed point and a ground strap point, the second feed point and the ground strap point are spaced apart from each other, the ground strap point is connected to a common ground terminal, and the second feed source is connected to the second feed point;
• the second radiator is configured to support a third frequency band and a fourth frequency band under a second excitation signal generated by the second feed source, and the first radiator and the second radiator are further configured to, under the second excitation signal generated by the second feed source, jointly support the third frequency band and the fourth frequency band, the fourth frequency band being a WiFi 2.4G frequency band or a Bluetooth 2.4G frequency band;
• and
• a third antenna comprising a third radiator and a third feed source, wherein there is a second gap between the third radiator and a second terminal of the second radiator, the third radiator is capable of being coupled with the second radiator through the second gap, the third feed source is connected to a third feed point of the third radiator, and the third radiator and a part of the second radiator are configured to support the second frequency band and a WiFi 5G frequency band under a third excitation signal generated by the third feed source.
