Abstract

The application relates to the communication technical field, discloses an electronic device, which comprises a slot antenna, a first tuning circuit, a second tuning circuit, and a first feeding circuit for transmitting telecommunication signals of satellite communication and cellular network frequency bands, and the slot antenna comprises a first radiator and a second radiator which are spaced apart along a first direction. The first radiator comprises a first grounding point, a first end, a feeding point coupled with the first feeding circuit, and a first position coupled with the first tuning circuit, and the second radiator comprises a second grounding point, a second end, and a second position coupled with the second tuning circuit. A gap is formed between the first end and the second end, and the first grounding point and the second grounding point are respectively one end of the first radiator and the second radiator which is far away from the gap. The ratio of the distance between the feeding point and the first end along the extension direction of the first radiator to the length of the first radiator is less than or equal to 1 / 2, and the ratio of the distance between the second position and the second end along the extension direction of the second radiator to the length of the second radiator is greater than or equal to 1 / 3. The slot antenna has high isolation from other antennas.
