CHARACTERISTICS OF BURIED ANTENNAS

Abstract

IENTIFIERS: Buried antennas. Horizontal electric dipoles buried in the ground are studed with special attention to their radiation efficiency at VLF and LF. The fundamental role of the currents excited in the ground and the need for low conductivity ground are emphasized. Discrepancies systematically observed between measured and computed values of the distant fields are atibuted to cerain insfficencies of a previously availabe analysis. A modified treatment based on the equivalence of buried antennas (electric of magnetic dipoles) and of a magnetic dipole over a lossy ground is presented. According to this treatment, lower vales of the raiation efficiency are to be expected theoretically. The results of the low field measurements appear, therefore, justified. (Author)
