Metamaterial Antennas for RADAR and SAR
Metamaterial Antennas for RADAR and SAR
Os sistemas de RADAR e Radar de Abertura Sintética (SAR) necessitam de antenas diretivas com banda larga. Para as antenas serem diretivas é necessário que estas sejam grandes, o que é impraticável em muitas aplicações. As antenas com metamateriais são construídas usando estruturas miniaturizadas complexas que permitem que antenas pequenas se comportem como antenas consideravelmente maiores. O objetivo desta tese é obter um conjunto baseado em pequenas antenas com tais propriedades, de forma a obter uma antena diretiva e de banda larga, passível de ser usada para operações de RADAR e SAR.
RADAR and Synthetic Aperture Radar (SAR) system require broadband directive antennas. Directivity require antennas to be large, which turns to be impracticable in many applications. Metamaterial antennas are built using complex miniaturized structures that produce small antennas that behave equally to much larger traditional antennas. The goal of this dissertation is to obtain a small antenna array based on small antennas with such properties, in order to obtain a directive and broadband antenna suitable for RADAR and SAR operation.
