Microstrip antenna and electronic device

An electronic device, wherein the electronic device comprises:

• a circuit board;
• and
• a microstrip antenna, comprising:
• a radiator electrically connected to the circuit board;
• and
• a first feed and a second feed,
• wherein a first feedpoint and two second feedpoints are disposed on the radiator, the first feedpoint is located at a central position of the radiator and is electrically connected to the first feed, the first feedpoint is configured to feed a first radio frequency signal into the radiator to excite the radiator to generate a TM02 mode, and
• wherein the two second feedpoints are spaced apart from the first feedpoint, the second feed is electrically connected to the second feedpoints through an adjustment circuit, the second feedpoints are configured to feed a second radio frequency signal into the radiator, and the second feedpoints are configured to excite the radiator to generate a TM10 mode through the adjustment circuit to perform as a dual-microstrip antenna.
