Abstract

Through analyzing the characteristic of antenna near-fields calculation with the aperture integration (AI) theory and the plane wave spectrum (PWS) theory

a hybrid algorithm of antenna near-fields is obtained.By combining it with the surface integration (SI) technique

the aperture integration /spectrum area integration-surface integration (AI/SAI-SI) method is presented

to simulate the electromagnetic performance of three-dimension antenna-radome system.The method united advantages of the AI and the PWS theory is more practical and precise for the analysis of antenna near-fields.By taking a missile radome as simulation example

the results indicate that the proposed method is more agreeable to the experimental data than the AI-SI method and the PWS-SI method.
