Abstract

Se proporciona una antena helicoidal de multiples segmentos acoplados, que tiene una longitud que es más corta que la obtenible de otro modo para una antena de media longitud de onda convencional. La antena helicoidal de multiples segmentos acoplados incluye una porcion de radiador (800) que tiene una pluralidad de radiadores helicoidalmente enrollados (804) que se extienden desde un extremo (832) de la porcion de radiador hacia el otro extremo (834) de la porcion de radiador (800). Cada radiador (804) se elabora de un conjunto de dos o más segmentos (708, 710). Un primer segmentos (708) se extiende de manera helicoidal desde el primer extremo (832) de la porcion de radiador (800) hacia el segundo extremo (834) de la porcion de radiador. El segundo segmento (710) se extiende de manera helicoidal desde el segundo extremo (834) de la porcion de radiador (800) hacia el primer extremo (832) de la porcion de radiador, en donde una porcion de dicho primer segmento de radiador (708) se encuentra en proximidad con una porcion de dicho segundo segmento de radiador (710) de tal manera que dichos primer y segundo segmentos de radiador (708, 710) se acoplen electromagnéticamente entre sí.
