Antenna system and electronic device

An electronic device, comprises an antenna system, wherein the antenna system comprises one near field communication (NFC) antenna and N conventional antennas, each of the N conventional antennas comprises a feed point, a grounding point, and a radiating branch, M conventional antennas in the N conventional antennas comprise blocking devices, an ith antenna comprises an ith radiating branch, an ith feed point, an ith blocking device, and an ith grounding point, the ith radiating branch is coupled to the ith feed point, the ith radiating branch is coupled to the ith grounding point through the ith blocking device, and the ith antenna is any one of the M conventional antennas;

• the blocking device is configured to block a radio frequency signal in a frequency band of the NFC antenna in the M conventional antennas, and N is an integer greater than or equal to M, and M is a positive integer:
• and
• in an operating process of the NPC antenna, the M conventional antennas are within a field strength range of radiation of the NFC antenna.
