Abstract

"ANTENA DIRECIONAL E SEU USO". Uma antena direcional operável em múltiplas bandas de freq³ência inclui um elemento de antena ativo e pelo menos um elemento de antena passivo parasiticamente acoplado ao elemento de antena ativo. 0(s) elemento(s) de antena passivo(s) tem extensão e espaçamento substancialmente otimizado para operar em (i) uma freq³ência fundamental associada com o elemento de antena ativo e (ii) uma freq³ência ressonante superior relacionada com a freq³ência fundamental. Distribuições de corrente de harmónico espacial dos elementos de antena passivos são usadas para criar as múltiplas bandas de freq³ência de operação. A antena direcional também inclui dispositivos operativamente acoplados ao(s) elemento(s) de antena passivo(s) para dirigir um feixe de antena formado aplicando um sinal na freq³ência ressonante fundamental, freq³ência ressonante superior, ou ambas ao elemento de antena ativo para operar nas múltiplas bandas de freq³ência.
