Abstract

Le doublet replié en plaques comporte un brin alimenté constitué de deux demi-plaques séparées par une coupure et alignées suivant le même axe. Le brin replié est constitué de deux demi-plaques étroites, simétriques par rapport au centre de symétrie du brin alimente et séparées des côtés adjacents des demi-plaques larges par un intervalle. Les extrémités- extérieures des demi-plaques larges sont réunies aux extrémités extérieures, des demi-plaques larges adjacentes. La coupure entre les demi-plaques est relativement large. Une antenne à polarisation circulaire est constituée par deux doublets ci-dessus qui ont même centre de symétrie, mêmes dimensions et décalés angulairement de 90 degrés et alimentés en quadrature de phase. Utilisable notamment pour des antennes plaques de télémétrie.
