Electronic device

An electronic device, comprising:

• a first main body and a second main body which move relative to each other, wherein the first main body has a first functional surface and a first metal shell facing away from the first functional surface;
• the second main body has a second functional surface and a second metal shell facing away from the second functional surface;
• the first metal shell has a first slot;
• and the second metal shell has a second slot;
• and
• an antenna circuit disposed in the first metal shell, wherein the antenna circuit has a radiator;
• and the radiator and the first slot satisfy a coupling condition, wherein:
• the electronic device has a first state and a second state;
• in response to being in the first state, the radiator and the second slot satisfy the coupling condition, and the radiator radiates a signal through the first slot and the second slot, simultaneously;
• and in response to being in the second state, the first slot and the second slot do not satisfy the coupling condition, and the radiator radiates the signal through the first slot.
