Analytical versus Numerical Approach to the Analysis of Dipole Antenna Radiated Field over a Lossy Ground
The paper deals with a comparison of numerical and analytical approaches to study the fields radiated from dipole antenna radiating above a homogeneous ground. The frequency domain formulation is based on the integro differential equation of the Pocklington type. The influence of the earth-air interface is taken into account via the Fresnel reflection coefficient. The Pocklington equation is solved via the Galerkin-Bubnov variant of the Indirect Boundary Element Method (GB-IBEM). The related reflected field is determined by numerically evaluating field integrals. Analytical approach involves the use of the approximate sinusoidal current distribution and analytical evaluation of field integrals. Some illustrative numerical results for the electric field reflected from the interface and propagated through the lossy medium obtained by both approximations are given in the paper.
