Abstract

"ANTENA DIELETRICAMENTE CARREGADA". Trata-se de uma antena de quadro dieletricamente carregada que possui um núcleo dielétrico cilíndrico (12), uma estrutura do alimentador (18) passando axialmente através do núcleo, um transformador simétrico-assimétrico da manga (20) envolvendo uma parte de extremidade do núcleo e elementos de antena helicoidais (10A - 10B) se estendendo a partir de uma conexão de alimentação com a estrutura do alimentador na outra extremidade do núcleo até a beira (20U) do transformador simétrico-assimétrico. Os elementos de antena (10A - 10D) são dispostos como um par de grupos lateralmente opostos (10A13, 10CD) de elementos helicoidais alongados condutores, cada um possuindo pelo menos o primeiro e segundo elementos condutores de diferentes extensões elétricas para formar uma pluralidade de caminhos condutores com voltas. Por formar pelo menos um dos elementos condutores em cada grupo como uma tira condutora com uma ou ambas bordas serpentiadas, de modo que as bordas da tira não sejam paralelas e possuam diferentes extensões elétricas, modos de ressonância adicionais são criados, produzindo um aperfeiçoamento na largura de banda.
