Abstract

ANTENA. é provida uma antena cujo formato externo pode ser miniaturizado, enquanto se mantém um ganho em um nível desejado com respeito a uma onda de rádio de uma faixa de frequência ampla. A antena é configurada pelo uso de um núcleo 1 de uma estrutura laminada. O núcleo é uma placa de um formato externo retangular, configurada para transmissão uma estrutura laminada incluindo cada uma dentre as primeira, segunda e terceira camadas de resina. A primeira camada de resina la tem um pó magnético misturado ali e formada como uma camada média, e a segunda camada de resina lb e a terceira camada de resina lc feitas de resina apenas sem um pó magnético misturado ali são formadas para intercalarem a primeira camada de resina la entre elas. No núcleo 1 da estrutura laminada, é preferível usar uma resina de polímero para cada uma das camadas de resina, e usar um pó de ferrita facilmente desmagnetizável como o pó magnético.
