Abstract

Se describe una antena que tiene arrollamientos o bobinados que están arrollados opuestamente en segmentos en una forma toroidal, y que tienen corrientes opuestas sobre segmentos seleccionados. Se describe una antena que tiene uno o más circuitos conductores aislados, con arrollamientos que están arrollados opuestamente alrededor y sobre la superficie multiplemente conectada, tal como una superficie toroidal. Los circuitos conductores aislados pueden formar una o más vías conductoras sinfin alrededor y sobre la superficie. Los arrollamientos pueden tener un patron helicoidal, un patron en general helicoidal, un patron parcialmente helicoidal, un patron poloidal-periférico, o pueden ser construidos a partir de un conductor ranurado sobre el toroide. Se describen los bobinados de rizo o vuelta poloidal con un cubo toroide sobre un toroide que tiene dos placas, que proporciona una alimentacion capacitiva a las vueltas, las cuales están selectivamente conectadas a una de las placas. Se desribe también los métodos asociados.
