Abstract

"ANTENA REFLETORA MELHORADA COM ALIMENTAçãO AUTO-SUPORTADA". A invenção consiste de melhorias de antenas refletoras com alimentações auto-suportadas. A alimentação consiste de um tubo guia de onda, uma junta dielétrica e um sub-refletor. O tubo é ligado ao centro do refletor rotacionalmente simétrico e se estende até a região focal dele. O sub-refletor está localizado na frente do tubo, e a superfície deste sub-refletor é provida com ranhuras rotacionalmente simétricas também chamadas ondulações. As melhorias da presente invenção são (1) um refletor de foco em anel para melhorar o ganho da antena, (2) uma região central elevada do refletor para reduzir a perda de retorno, (3) parafusos ou cilindros de metal para prender fortemente o sub-refletor ao tubo, (4) ondulações ou outros meios similares ao redor da borda ou do refletor para reduzir lóbulos laterais afastados, (5) operações em banda dupla por meio de uma guia de onda coaxial fora da guia de onda circular no tubo, e (6) enchimento ou cobertura dielétrica das ondulações ou da região entre as ondulações e a extremidade do tubo, ambos para evitar o ajuntamento de água, poeira ou outro material indesejado nesta área o que poderia destruir o desempenho da antena.
