Abstract
An onboard antenna, a radio equipment and an electronic device. The onboard antenna includes a dielectric substrate, an antenna and a metal block, wherein the antenna is located on the dielectric substrate, a projection of the metal block on a plane where the dielectric substrate is located is not overlapped with a projection of the antenna on the plane where the dielectric substrate is located, the metal block is located on the dielectric substrate in a polarization direction of the antenna, and a distance between a metal edge of the metal block on a side close to the antenna and the antenna is greater than a coupling threshold. Using this onboard antenna, an influence of surface waves on the pattern can be suppressed to a certain extent by arranging the metal block, and a jitter of the antenna pattern can be reduced.
