Abstract:
In this paper, the hybrid physical optics/boundary integral-finite element-mode matching (PO/BI-FE-MM) method is proposed for the analysis of the horn antenna enclosed by the electrically large radome. The radome is modeled by the PO method, and the BI-FE-MM method is implemented to the horn region. The equivalent PO currents on the radome surface are coupled into the BI-FE-MM equation of the horn region to account for the effects of the radome on the horn. With this hybrid method, the mutual interactions between the radome and the horn are fully considered. The radiation patterns, field distributions, and the S-parameters of the horns enclosed by different kinds of radome are presented.
