Microstrip antenna and electronic equipment

The invention provides a microstrip antenna, and the antenna comprises a dielectric substrate which is provided with a first surface and an opposite second surface; the radiator is attached to the first surface; the radiator comprises a main radiator and an auxiliary radiator; the auxiliary radiator comprises a plurality of pairs of coupling patches which are symmetrically distributed on the two sides of the main radiator; one end of the main radiator is a feed end; the main radiator has a first radiation frequency, and the coupling patch is used for being coupled with the main radiator to increase the gain of the main radiator at the first radiation frequency; the first grounding body is attached to the first surface and is adjacent to the feed end; and the floor is attached to the second surface and is connected with the first grounding body through a conductive through hole penetrating through the dielectric substrate. According to the microstrip antenna provided by the invention, the gain and bandwidth of
