ABSTRACT The purpose of this paper is t o obtain the admittance of a monopole antenna t o a higher degree of accuracy than has heretofore been reported in the literature. The model selected for analysis consists of a basedriven monopole of a r b i t r a r y dimensions (length and radius) protruding perpendicularly from an infinite ground plane. providing the excitation is a coaxial cable with outer sheath truncated at Grs 2 Extensive numerical results in tabular and graphical form a r e provided in the paper.
