Abstract
A quadrature coil system which includes the following elements. (1) First and second electric main conductors which are situated at a distance from one another in a first plane and a second plane, respectively, and each of which is formed as a loop with an opening, the main conductors having mainly the same orientation. (2) First and second connection conductors, each of which constitutes an electric connection between the free ends of the first and second main conductors, which free ends are situated to corresponding sides of the opening. (3) An electric connection device which is connected to the conductors so that first and second sets of turns are formed which are suitable to generate and/or receive first and second magnetic fields, respectively, which are mutually orthogonally directed. (a) There is provided at least one third connection conductor which constitutes an electric connection between a point on the first main conductor, being situated between the two free ends, and a corresponding point on the second main conductor; (b) each of the first and second connection conductors consist of substantially equal first and second connection conductor portions, the first connection conductor portions being connected to the free ends of the first main conductor and the second connection conductor portions being connected to the free ends of the second main conductor; (c) the four ends of the first and second connection portions are electrically connected, via an electric connection network, to one another and to the electric connection device.
