Abstract
A microstrip antenna, an antenna array, a radar, and a vehicle are provided. The microstrip antenna includes: a dielectric layer, and a metal layer and a ground plane layer disposed at two sides of the dielectric layer, wherein the metal layer includes a first radiation patch and a feeding portion; a length of a long side edge of the first radiation patch is determined based on an operating wavelength of the microstrip antenna, and a length of a short side edge of the first radiation patch is smaller than the length of the long side edge; the feeding portion is coupled between a center position of the long side edge of the first radiation patch and a short side edge, and the feeding portion is configured to transmit a high frequency signal to the first radiation patch or to transmit a space radiation signal received by the first radiation patch.
