A comparative numerical study of several techniques for modeling a horizontal wire antenna over a lossy half‐space Academic Article uri icon


  • The electric‐field integral equation for the current on a thin, horizontal wire antenna radiating above a lossy half‐space is solved by the method of moments, with the effect of interface included via the Sommerfeld integrals, the well‐known reflection‐coefficient approximation and the high‐contrast approximation. A modified implementation of the reflection‐coefficient approximation is suggested, which makes this technique reasonably accurate for antennas near the interface. A comparison is made between the methods for several cases of practical interest. The high‐contrast approximation is shown to be superior to the reflection‐coefficient approximation.
