Abstract

"SISTEMA DE DIVERSIDADE DE ANTENA PARA UM TELEFONE MóVEL". Um sistema e método são fornecidos para diversificar comunicações eletromagnéticas irradiadas em um dispositivo de telefone sem fio. O método compreende: montar antenas internas em um chassi de dispositivo de telefone sem fio; perceber sinais de linha de transmissão eletromagnéticos conduzidos comunicados pelas antenas; e selecionar enter as antenas em resposta à percepção dos sinais de linha de transmissão. Em alguns aspectos, a percepção de sinais de linha de transmissão inclui perceber níveis de potência de sinal de linha de transmissão. Por exemplo, os níveis de potência de sinal de linha de transmissão de sinais transmitidos refletidos pelas antenas são detectados. Em outros aspectos, a percepção dos sinais de linha de transmissão inclui perceber os sinais irradiados recebidos nas antenas e conduzidos na linha de transmissão. Por exemplo, os níveis de potência dos sinais irradiados conduzidos nas linhas de transmissão podem ser percebidos. Alternativamente, os sinais irradiados são recebidos e decodificados. Então, a antena que fornece o sinal de linha de transmissão com o menor número de erros de decodificação é selecionada.
