Abstract

Patente de Invenção: ANTENA DE SUBSTRATO INCORPORANDO UM ELEMENTO QUE IMPEDE O ACOPLAMENTO DE ENERGIA ENTRE A ANTENA E CONDUTORES. Um elemento parasita (800, 900) para uso com uma antena interna (300) em um dispositivo sem fio (100, 700). De um modo geral, a antena é uma antena de substrato (300) com uma ou mais trilhas condutoras (302) suportadas sobre um substrato (304) e montada afastada ou deslocada de um plano terra (504, 508) associado com o dispositivo sem fio. Um ou mais condutores, cabos, ou alimentações de sinal (712) de transferência de sinal ou energia são posicionados imediatamente adjacentes à antena (300), os quais são capazes de acoplar sinais à antena a qual capta energia a partir de campos em torno ou emanando a partir dos condutores. Alternativamente, os condutores interceptam uma parte da energia sendo transferida para a antena (300). O elemento de malha parasita (800, 900) emprega uma estrutura condutora delgada que é posicionada adjacente, sobre ou sob tais condutores (712), reduz uma porção substancial de energia do acoplamento entre os condutores e a antena alterando as características ressonantes ou de acoplamento de energia dos condutores. O elemento parasita (800, 900, 902, 904, 906) inibe a transferência de energia entre os condutores e a antena, o que aumenta o ganho total do dispositivo. Além disso, o elemento parasita e o acoplamento parasita do elemento parasita ao plano terra, aumenta o ganho e a largura de banda dos dispositivos sem fio. O elemento parasita pode ser fabricado a partir de uma diversidade de materiais e em uma variedade de formatos (800, 900, 902, 904, 906) e ser instalado usando-se uma variedade de técnicas conhecidas para o posicionamento e instalação de camadas condutoras ou metálicas delgadas de material.
