Abstract
An antenna includes a substrate and a radiator fixed to the substrate. A thermal protection system for the antenna includes a thermal protection sheet body opposite to and spaced from the antenna, where the thermal protection sheet body separates the antenna from an external heat source; and a groove body formed in the thermal protection sheet body, where the radiator generates an antenna near field toward the outside, and an inner wall of the groove body is adapted to an edge of the antenna near field to reduce the deterioration of antenna performance caused by the thermal protection sheet body. The overall electrical performance and the thermal protection performance of the thermal protection system can be well balanced by decreasing the thickness of a middle area of the thermal protection system or by etching a groove in a certain shape in the thermal protection system.
