Analysis of Antenna Array with Arbitrarily Shaped Radomes Using Fast Algorithm Based on VSIE

Abstract

The moment method (MoM) based on volume-surface integral equation (VSIE) combined with the adaptive integral method (AIM) is applied to analyze antenna array radiation in the presence of arbitrarily shaped radomes. The application of AIM reduces the computational complexity of MoM, which leads eclectically large-sized radomes with metal reflecting ground can be analyzed accurately and efficiently. Some radomes terminated by metal plane is presented and the effect of the metal plane on the radiation of antenna is analyzed.
