Input impedance of a horizontal dipole antenna in close proximity of a lossy half-space is determined in this paper. Integrals of Sommerfeld’s type are approximately solved applying a simple model for the spectral reflection coefficient that is a part of their integrand. The system of integral equations of Hallén’s type is numerically solved using the point-matching method, assuming the polynomial approximation for the current along the antenna conductors. Obtained results will be graphically illustrated and compared to corresponding ones of other authors.
