Radiation characteristics of short/thick solid antenna with finite feed GAP

摘要

Expressions are presented for the input admittance and the current distribution along a linear antenna without restrictions on either the length or the thickness. These expressions which are based on Hurd's Wiener-Hopf type analysis, are used to find the characteristics of short as well as thick antennas. It is found that although using one term of the solution asymptotic series produces accurate results for thick antennas, more series terms have to be used when the antenna is thin.
