Abstract: A microstrip antenna includes a radiator and a first feed and a second feed that are configured to feed a radio frequency signal, and 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 the first feedpoint is electrically connected to the first feed, and is configured to feed a radio frequency signal into the radiator, to excite the radiator to generate a TM02 mode. The two second feedpoints deviate from the central position of the radiator and 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 radio frequency signal into the radiator, and the second feedpoints excite, by using the adjustment circuit, the radiator to generate a TM10 mode.
