Abstract

Los brazos (310, 320, 330, 340) de un elemento de antena se conectan a una red de conversion balanceada-desbalanceada (510) en un punto de alimentacion de excitacion para proporcionar un ensamblaje de antena. Se proporcionan características tales como el tamaño del ensamblaje de antena al proporcionar un elemento de sintonizacion cerca de las conexiones (610, 620) hacia un punto de alimentacion de excitacion. El elemento de sintonizacion (410) se conecta eléctricamente a uno de los brazos (330) pero se coloca con un intervalo entre un brazo circundante (320). También puede proporcionarse un intervalo entre el elemento de sintonizacion (410) y un punto de alimentacion de excitacion. Los brazos y el elemento de sintonizacion son preferentemente brazos metálicos delgados formados sobre un tubo dieléctrico alargado (210) en la construccion preferida de la invencion. La red de conversion balanceada-desbalanceada (510) también puede colocarse dentro del tubo dieléctrico alargado (210) de acuerdo a la construccion preferida.
