Abstract

META-ANTENA. Um sistema de meta-antena pequeno, barato e imprimível é descrito. Além de ser antenas menores do que as existentes, a meta-antena é melhor por ser omnidirecional e ter uma função de ganho mais ampla e melhor eficiência. Algumas modalidades incluem um elemento principal com uma forma de uma volta e dois elementos parasíticos encerrados pelo elemento principal. Cada elemento parasítico pode ser formado como um laço com uma abertura. As aberturas dos dois elementos parasíticos podem ser posicionadas adjacentes aos lados opostos do elemento principal, respectivamente.
