Abstract
A single element, multi-frequency dipole antenna including two substantially equal arm sections of conductive material extending co-axially in a straight line in opposite directions from each other, each arm section being a mirror image of the other arm section throughout its entire length, each arm section including at least two contiguous shorter sub-sections of j.sub.1, j.sub.2, . . . j.sub.n lengths, wherein j.sub.1 represents the length of the innermost sub-section, sub-sections terminated by discontinuities wherein j.sub.1 represents the 1/4 wavelength of the highest resonant frequency and each consecutive-integer sequence of j sub-sections represent the 1/4 wavelength of lower resonant frequencies.
