Title
(EN) INDUCTOR STRUCTURE
(FR) STRUCTURE DE BOBINE D’INDUCTION
Abstract
(EN) An inductor structure comprising: a first loop (301) and a second loop (302); a first feed line (308) connected to a first end (303) of the first loop and a second feed line (309) connected to a first end (306) of the second loop, each of the first and second feed lines extending through an area circumscribed by one of the first and second loops; and a crossover section (310) adjacent to the first end of the first loop and the first end of the second loop, the crossover section coupling the first loop to the second loop so as to cause current flowing from the first feed line to the second feed line to circulate around the first loop in a first rotational direction and around the second loop in a second rotational direction opposite to the first rotational direction.
(FR) L’invention concerne une structure de bobine d’induction comprenant : une première boucle (301) et une seconde boucle (302) ; une première ligne d’alimentation (308) connectée à une première extrémité (303) de la première boucle et une seconde ligne d’alimentation (309) connectée à une première extrémité (306) de la seconde boucle, chacune des première et seconde lignes d’alimentation s’étendant à travers une zone circonscrite par l’une des première et seconde boucles ; et une section de jonction (310) adjacente à la première extrémité de la première boucle et à la première extrémité de la seconde boucle, la section de jonction couplant la première boucle à la seconde boucle de sorte que le courant circulant de la première ligne d’alimentation à la seconde ligne d’alimentation circule autour de la première boucle dans un premier sens de rotation et autour de la seconde boucle dans un second sens de rotation opposé au premier sens de rotation.
