To study the influence of high temperature on the electrical properties of thermal antennas, a thermoelectric coupling calculation method is proposed in this paper. The 3D grids information for both temperature field and electromagnetic field are associated by a designed information transfer program, which loads corresponding dielectric parameters based on local temperature to achieve thermoelectric coupling analysis. This paper presents the principle of thermoelectric coupling calculation. To realize fine design of aircraft thermal antenna, the directional patterns of a thermal antenna at room temperature and high temperature are studied and compared. The method can be used to analyze the electrical properties of heat wave-transmitting structure at high temperature, and has an important application in thermal antenna/radome design in harsh thermal environment.
