Single-element, multi-frequency, dipole antenna

摘要

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 j1, j2, . . . jn lengths, wherein j1 represents the length of the innermost sub-section, sub-sections terminated by discontinuities wherein j1 represents the +E,fra 1/4+EE wavelength of the highest resonant frequency and each consecutive-integer sequence of j sub-sections represent the +E,fra 1/4+EE wavelength of lower resonant frequencies.
