Abstract

"SISTEMA E MéTODO PARA REGULAR COMPRIMENTO ELéTRICO DE ANTENA". São fornecidos um sistema e método para regular o comprimento elétrico de uma antena. O método compreende: comunicar sinais de linha de transmissão em uma freqüência predeterminada entre um transceptor e uma antena; perceber sinais de linha de transmissão; e modificar o comprimento elétrico de antena em resposta à percepção dos sinais de linha de transmissão. A percepção dos sinais de linha de transmissão significa tipicamente perceber os níveis de potência de sinal de linha de transmissão. Em alguns aspectos, a impedância de antena é modificada. Alternativamente, pode ser dito que a intensidade de sinal da linha de transmissão é otimizada entre o transceptor e a antena. Mais especificamente, a comunicação dos sinais de linha de transmissão em uma freqüência predeterminada entre um transceptor e uma antena inclui aceitar o sinal de linha de transmissão do transceptor em uma porta de antena. Então, a percepção dos sinais de linha de transmissão inclui medir o sinal de linha de transmissão refletido da porta de antena.
