Abstract

Patente de Invenção: <B>"ANTENA TOROIDAL"<D>. é divulgada uma antena (48) que tem um ou mais circuitos de condutor isolados (56, 58) com enrolamento que são contrabobinados em torno de uma superfície conectada de modo múltiplo (TF) e sobre a mesma, tal como uma superfície toroidal (TF). A superfície conectada de modo múltiplo (TF) tem um raio maior e um raio menor, com o raio maior sendo pelo menos tão grande quanto o raio menor. Os circuitos de condutor isolados (56, 58) estendem-se em uma primeira trajetória condutiva helicoidal em torno da superfície conectada de modo múltiplo (TF) e sobre a mesma, com o primeiro sentido de passo helicoidal de um primeiro nó (60) para um segundo nó (62), e também estendem-se em uma segunda trajetória condutiva geralmente helicoidal em torno da superfície conectada de modo múltiplo (TF) e sobre a mesma, com um segundo sentido de passo helicoidal, que é oposto ao primeiro sentido de passo helicoidal, do segundo nó (62) para o primeiro nó (60), a fim de que as primeira e segunda trajetórias condutivas geralmente helicoidais sejam contrabobinadas em relação uma à outra e formem uma única trajetória condutiva sem fim em torno da superfície conectada de modo múltiplo (TF) e sobre a mesma. Um primeiro terminal de sinal (52) é conectado eletricamente ao primeiro nó (60) e um segundo terminal de sinal (54) é conectado eletricamente ao segundo nó (62). Os circuitos de condutor isolados (56, 58) podem formar uma ou mais trajetórias condutivas sem fim em torno da superfície conectada de modo múltiplo (TF) sobre a mesma. Os enrolamentos podem ter um padrão helicoidal, poloidal-periférico ou podem ser construídos a partir de um condutor fendido sobre o toróide. é divulgado também o método associado.
