Starting from outdoor transmission, crossing vegetation, the wideband and narrowband characterization of the indoor mobile radio channel in the 700 MHz band is obtained from experiments carried out in the indoor environment of the Engineering building at Fluminense Federal University, and from the processed data, respectively, the power-delay profiles obtained permitted to calculate the time dispersion parameters and the envelope of the signal permitted to adjust probability density functions to the signal variability, concluding about the influence of vegetation on those characteristics.

Resumo-Este artigo apresenta o projeto de uma antena microstrip impressa do tipo loop realizada no substratro FR-4, e considera desde a etapa de simulação até a fabricação do protótipo, operar na faixa do espectro de UHF objetivando as bandas de 400 MHz, 1.2GHz e 1.8GHz. Os resultados medidos e simulados comprovaram a recepção indoor dos sinais de DTV e de sistema móvel em 1.8 GHz.
