Abstract: front page image
(EN)The present invention relates to an antenna arrangement comprising means (1, 72, 72', 77, 77') for providing an approximation of a constant current electrical loop, which is arranged to provide a first essentially toroid-shaped radiation pattern (29), where the antenna arrangement further comprises a first (67) and a second (68) electrical dipole. The electrical dipoles (67, 68) are arranged essentially orthogonal to each other, and are arranged to provide a second (30) and third (31) essentially toroid-shaped radiation pattern which each is essentially orthogonal to the other and to the first essentially toroid-shaped radiation pattern (29). The means (1, 72, 72', 77, 77') for approximation of the constant current electrical loop comprises at least two current path parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), where a current (I1, 12, 13, 14) can be applied to each one of said parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), so that the current (11, 12, 13, 14) in each one of said parts (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76') essentially will be in phase with each other.
(FR)L’invention concerne une disposition d’antenne comprenant des moyens (1, 72, 72’, 77, 77’) permettant de fournir une approximation d’une boucle de courant électrique constante, qui est disposée de manière à fournir un premier diagramme de rayonnement essentiellement en forme de bobine (29), dans lequel la disposition d’antenne comprend un premier (67) et un second (68) dipôle électrique. Les dipôles électriques (67, 68) sont disposés essentiellement de façon orthogonale l’un à l’autre et sont disposés pour fournir un deuxième (30) et troisième (31) diagrammes de rayonnement essentiellement en forme de bobine en position orthogonale à l’autre et au premier diagramme de rayonnement essentiellement en forme de bobine (29). Les moyens (1, 72, 72’, 77, 77’) destinés à l’approximation de la boucle électrique de courant constant comprend au moins deux parties de lignes de courant (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), dans lesquelles un courant (I1, 12, 13, 14) peut être appliqué à chacune desdites parties (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76'), de sorte que le courant (11, 12, 13, 14) dans chacune de ces parties (2, 3, 4, 5; 69, 70, 71; 69', 70', 71'; 73, 74, 75, 76; 73', 74', 75', 76') sera essentiellement en phase l’un avec l’autre.
