A expansÃo das redes de telecomunicaÃÃes sem fio e o fenÃmeno da convergÃncia digital trazem a inerente necessidade da pesquisa de novos componentes que assegurem a sustentabilidade e a evoluÃÃo dos sistemas. Novos tipos de antenas, menores e mais eficientes, sÃo exigidas à medida que novos dispositivos vÃo surgindo. Neste contexto, as antenas ressoadoras dielÃtricas, construÃdas com novos materiais, aparecem como excelente opÃÃo para substituir as antenas metÃlicas tradicionais. Este trabalho apresenta uma proposta de antena ressoadora dielÃtrica circularmente polarizada, operando na frequÃncia central de 2,25 GHz, na qual um esquema de alimentaÃÃo por sonda Ãnica à empregado para excitar dois modos ressonantes em um dielÃtrico em forma de...
