Abstract

"ANTENA PLANAR COM IMPEDáNCIA E/OU POLARIZAçãO COMBINADAS". A presente invenção refere-se a uma antena planar suportada por um substrato compreendendo uma ranhura (F) na forma de uma curva fechada dimensionada para operar em uma dada freqüência, suprida por uma linha de alimentação atravessando a ranhura (F) em um ponto conhecido como um ponto de excitação (E), caracterizada pelo fato de que pelo menos dois circuitos curtos (SC) em paralelo na ranhura (F) são posicionados com respeito a um ponto de excitação (E) de modo a combinar a impedância no ponto de excitação (E) e/ou a polarização da antena.
