Radiation characteristics analysis of wire antenna partially embedded in the ground

Mixed-potential integral equation (MPIE) combined with method of moment is used to analyze the wire antenna partially embedded in the ground. Some key techniques such as the calculation of Sommerfeld integrals, impedance matrix element and radiation field are discussed in this paper. Radiation characteristics of wire antennas partially embedded in the ground are calculated, and the results obtained are compared with that of the FEKO software, which confirms the correctness of this method. Compared with FEKO and other electromagnetic software, the approach presented in this paper has obvious advantages in computational efficiency for electromagnetic characteristics analysis of the object penetrating planar layered media.
