Abstract : The paper poses, and attempts to answer, some of the questions involved when a UHF antenna is buried in the ground. A description of the basic theory is given, together with illustrative calculations for many situations of interest. Graphs are presented for the patterns and related parameters of a variety of buried antennas, including electric and magnetic doublets, half-wave dipoles, and the annular slot antenna. It is hoped that these graphs may be of direct help in designing systems which must use such buried antennas. Of all the antennas investigated, for example, it is the annular slot which seems to be the most efficient radiator. (Author)
