摘要

In this paper, a novel hybrid method combining the full-wave integral equation and high-frequency approaches is proposed to assess the electromagnetic performance of the radome and thermal protective enclosure (TPE)-enclosed antenna (RTA) structure. By using the approximate equivalence principle twice, the basic difficulty in applying the previously proposed hybrid method to RTA structure is eliminated. The interactions between the antennas and TPE, as well as between the combined antenna-TPE system and the radome, are accounted for iteratively. Numerical results demonstrate that the proposed hybrid method computes the radiation patterns of RTAs with good accuracy and significantly higher efficiency compared to full-wave solutions.
