Coupled vertical mast (monopole) antennas in the presence of a conducting half-space

The unknown current distribution (UCD), self and mutual admittances (impedances), grounding impedances of coupled vertical mast antennas (CVMA) on a conducting half-space are presented in this paper. The UCD is determined by numerical solving of the system of integral equations of two potentials (SIE-TP). The simplified Sommerfeld´s expressions for potentials (the Hertz vector potential and electric scalar potential) are used for establishing the SIE-TP. The influence of the earthing systems on the antenna characteristics are adequately treated.
