Abstract

"MéTODO PARA AVALIAR NìVEIS DO CAMPO ELéTRICO NA ZONA PRóXIMA DE ANTENAS DE TRANSMISSãO". O método para avaliar níveis do campo elétrico na zona próxima de antenas de transmissão, particularmente antenas de malha linear amplamente utilizadas em sistemas de telefonia celular, fornece avaliação precisa enquanto exige tempos de processamento reduzidos e um conjunto restrito de dados de entrada, como as dimensões externas físicas da antena, seu ganho e seus padrões de radiação no plano vertical e no plano horizontal.
