1. A thermal protection system for an antenna, wherein the antenna comprises a substrate and a radiator fixed to the substrate, and the thermal protection system comprises:
a thermal protection sheet body opposite to and spaced from the antenna, wherein the thermal protection sheet body separates the antenna from an external heat source; and
a groove body formed in the thermal protection sheet body, wherein the radiator generates a near radiation field of the antenna, a wall of the groove body is adapted to an edge of the near radiation field to reduce disturbance of the thermal protection sheet body to the near radiation field;
wherein parts of the thermal protection sheet body other than the groove body do not intersect with the near radiation field.
