In this paper, based upon the equivalent principle and surface integral equations, the exact model of an antenna and dielectric radome structure is established by using method of moments (MoM). The equivalent strip-model is used for the thin wire antenna, in order to alleviate the singularities in the meshing process. The ill-conditioned MoM matrix is improved by the preconditioning technique. The...
The radiation characteristics are presented for a three-element Yagi-Uda antenna enclosed in an electrically large Kaman radome. The discussion focuses on the influences of various structural parameters, such as the radome thickness, permittivity, size and the antenna position. The method of moments (MOM) is applied to the Yagi-Uda antenna, and the equivalent physical optics (PO) currents produced...
