Abstract(s)
Neste trabalho é averiguada a existência de uma relação directa entre estruturas físicas
unidimensionais e o respectivo diagrama de radiação.
São estudados diferentes métodos numéricos utilizados na análise de estruturas físicas
radiantes, com incidência nos métodos com aplicação no estudo de antenas.
O trabalho efectuado permite concluir que é possível relacionar directamente a excitação
de uma estrutura unidimensional com o factor de agrupamento e o diagrama de radiação dessa
estrutura.
O programa desenvolvido neste trabalho mostra como uma estrutura pode ser analisada
desta forma, com vantagens computacionais relativamente aos métodos clássicos.
This thesis examines the relation between unidirectional structures and radiation pattems. A review of the strengths and limitations of different numerical techniques for analysing electromagnetic configurations is presented, with particular emphasis on how these techniques could be applied to the problem. The work developed in this thesis lead to the conclusion that is possible to develop a direct relation between a unidirectional structure and the radiation pattem. Some examples of the program developed in this work show that the analysis of a structure is done with less considerable computer effort, with this approach.
