Previous issue date: 2013-06-28 / Nowadays there has been a major breakthrough in the aerospace area, with regard to rocket launches to research, experiments, telemetry system, remote sensing, radar system (tracking and monitoring), satellite communications system and insertion of satellites in orbit.
This work aims at the application of a circular cylindrical microstrip antenna, ring type, and other cylindrical rectangular in structure of a rocket or missile to obtain telemetry data, operating in the range of 2 to 4 GHz, in S-band.
Throughout this was developed just the theoretical analysis of the Transverse transmission line method which is a method of rigorous analysis in spectral domain, for use in rockets and missiles. This analyzes the spread in the direction "ρ" , transverse to dielectric interfaces "z" and "φ", for cylindrical coordinates, thus taking the general equations of electromagnetic fields in function of e [1].
It is worth mentioning that in order to obtain results, simulations and analysis of the structure under study was used HFSS program (High Frequency Structural Simulator) that uses the finite element method.
With the theory developed computational resources were used to obtain the numerical calculations, using Fortran Power Station, Scilab and Wolfram Mathematica ?.
The prototype was built using, as a substrate, the ULTRALAM ? 3850, of Rogers Corporation, and an aluminum plate as a cylindrical structure used to support.
The agreement between the measured and simulated results validate the established processes.
Conclusions and suggestions are presented for continuing this work / Nos dias atuais observa-se um grande avan?o na ?rea aeroespacial, no que se refere aos lan?amentos de foguetes, para pesquisas, experimentos, sistema de telemetria, sensoriamento remoto, sistema de radar (rastreamento e monitora??o), sistema de comunica??es via sat?lites e inser??o de sat?lites em ?rbita.
Este trabalho tem como objetivo a aplica??o de uma antena de microfita cil?ndrica circular, tipo anel, e outra retangular cil?ndrica na estrutura de um foguete ou m?ssel para obten??o de dados de telemetria, operando na faixa de 2 a 4 GHz, na banda S.
Ao longo deste foi desenvolvida apenas a an?lise te?rica do M?todo da Linha de Transmiss?o Transversa que ? um m?todo de an?lise rigoroso no dom?nio espectral, para aplica??o em foguetes e m?sseis. Este analisa a propaga??o na dire??o ρ , transversa ?s interfaces diel?tricas z e φ , para coordenadas cil?ndricas, tendo assim as equa??es gerais dos campos eletromagn?ticos em fun??o de e [1].
Vale ressaltar que para a obten??o dos resultados, simula??es e an?lise da estrutura em estudo foi utilizado o programa HFSS (High Frequency Structural Simulator) que utiliza o M?todo dos elementos finitos.
Com a teoria desenvolvida foram utilizados recursos computacionais para obten??o dos c?lculos num?ricos, atrav?s do Fortran Power Station, Scilab e o Wolfram Mathematica?.
O prot?tipo foi constru?do utilizando, como substrato, o ULTRALAM? 3850, da Rogers Corporation, e uma placa de alum?nio como suporte ? estrutura cil?ndrica utilizada.
A concord?ncia entre os resultados medidos e os simulados validam os processos estabelecidos.
S?o apresentadas sugest?es e conclus?es para a continuidade deste trabalho
