Abstract

PROCESSO DE MONTAGEM DE UMA ANTENA DE RADIOCOMUNICAçãO, ANTENA DE RADIOCOMUNICAçãO LIGADA SEGUNDO ESSE PROCESSO E DISPOSITIVO DESTINADO à APLICAçãO DESSE PROCESSO DE MONTAGEM.A presente invenção refere-se a um processo de montagem de uma antena de radiocomunicação, compreendendo um refletor ligado a um sub-refletor por intermédio de um guia de ondas (32) de seção circular e estendendo-se segundo um eixo longitudinal (36). De acordo com a invenção, esse processo é caracterizado pelo fato de compreender as seguintes etapas: - a etapa de giro do guia de ondas (32) em tomo de seu eixo longitudinal (36) para determinar uma posição tal que uma defasagem do plano de propagação de um campo eletromagnético polarizado transmitido por esse guia seja limitada; - a etapa de marcação (46) sobre o guia de ondas (32) dessa posição; e - a etapa de montagem desse guia de ondas sobre o refletor em função dessa marcação.
