Abstract

"ANTENA PLANAR FENDIDA COM DIVERSIDADE DE RECEPçãO". Descreve-se uma antena planar dotada de um substrato (2) contendo uma fenda de formato fechado (1), dimensionada para operar a uma freqüência específica e disposta em um plano de curto-circuito de, pelo menos, uma linha alimentadora (3, 4). Neste caso, o perímetro da fenda é selecionado, de forma que p = k<sym>s, onde k é um número inteiro superior a 1 e <sym>s, o comprimento de onda guiada na fenda. A antena ainda compreende, pelo menos, uma primeira linha alimentadora (3) disposta em uma zona de circuito aberto da fenda, e uma segunda linha alimentadora (4) disposta a uma distância d = (2n + 1) <sym>s/4 da primeira linha, sendo n um número inteiro não inferior a zero. A invenção é, de modo particular, aplicável a transmissões sem fio.
