Physical Resemblance

The problem of an electric line source above a conducting earth is investigated. Approximations to the integrals appearing in the solution of the problem are considered. An estimate of the neglected terms is given and interpretation of their physical resemblance is presented. The analysis does not restrict the relative magnitudes of earth and air propagation constants as in previous work. It is shown that the approximation presented is legitimate for far field computation and the results are comparable to those known for the quasi-static limit.

Far Field Pattern

The far-field pattern characteristics of line sources lying between the slabs of a four-dielectric substrate configuration are presented. The patterns are calculated for several cases of the substrate thickness as well as for several line-source locations. The considerations that are made give useful applications in remote sensing and microstrip antennas.
