Abstract :
The adaptive integral method (AIM) is employed to solve the volume integral equation (VIE) for analyzing the radiation of the antenna with an arbitrarily shaped radome. The small dipole antenna elements are used as exciting source. Modeling the radomes by tetrahedron cells, the induced volume current is determined by the AIM based on VIE. The application of AIM significantly reduces the CPU time and computer memory. Hence, the method presented in the paper can be applied to simulated electrically large sized radomes.
