Simulação e otimização de modelos de antenas em microfita para a integração em nano satélites

Abstract

This document seeks to present the procedures adopted for the development of a microstrip antenna, with a center frequency of 401 MHz and linear polarization, modeled through the transmission line method, using the Taconic CER-10 substrate in a rectangular patch, fed through a coaxial probe, considering a SMA connector, with the objective of integrating a link between the nanosatellites and the environmental data collection platforms of the Brazilian Data Collection System. Too, tests were carried out varying the permissiveness of the substrate, in order to observe the relationship of the magnitude with the total dimension of the antenna. Subsequently, the modeled patch passed by an optimization process through the HFSS software, seeking to improve its operating parameters and finally, the application of fractals to the model was tested, seeking perform the reduction of the dimensions of the patch.
