Abstract

A simple formula is described for the apparent admittance $Y(ka, b/a)$ of a monopole of fixed length $h$ and radius $a$ when driven from a coaxial line (conductor radii $b$ and $a$ ). If $Y(ka, b/a)$ is known at $n$ values of $ka$ with $b/a$ fixed at $(b/a)_{2}$ and at m values of $b/a$ with $ka$ fixed at $(ka)_{1}$ , it can be evaluated from the given formula for all combinations of $ka$ and $b/a$ in the two ranges of $n$ and $m$ . It is assumed that $kb \\ll 1$ and $h \\gg (b-a)$ .
