Abstract

"ANTENA PARA MúLTIPLAS FAIXAS DE SINTONIA". A presente invenção refere-se de uma maneira geral a uma nova família de antenas com um comportamento para múltiplas faixas de sintonia e com um tamanho reduzido. A configuração geral da antena consiste de uma estrutura de múltiplos níveis a qual proporciona o comportamento de múltiplas faixas de sintonia, em combinação com um plano de terra de múltiplos níveis e/ou de enchimento de espaço. A estrutura de múltiplos níveis consiste de dois braços de comprimento diferentes que seguem uma trajetória paralela sinuosa espaçada por um intervalo paralelo sinuoso (paralelo aos braços) com um formato substancialmente similar conforme cada um dos braços, isto é, com uma trajetória sinuosa similar conforme os braços. A antena resultante cobre os serviços sem fio principais correntes e os futuros, abrindo desta maneira uma ampla variedade de possibilidades no desenho de dispositivos e terminais sem fio universais, com propósito variado.
