Analysis of a Finite Length Tubular Monopole Antenna Driven by a Coaxial Line

摘要

In this paper, the problem of a coaxially-driven, finite length tubular monopole antenna over an infinite ground plane is formulated as a rigorous boundary value problem. The resulting coupled pair of singular integral equations is numerically solved for the electric field in the end of the coaxial line and for the total current on the antenna. The electric field is used to compute the admittance of the antenna. The admittance, electric field, and current are presented for a wide range of experimentally useful parameters.
