Abstract

The invention relates to a stripe-line inductor comprising one or more stripes conductor turns fabricated into one or more layers of a carrier substrate. The stripe conductor of the inductor is divided into parallel sub-stripe-lines (51, 52, 53, 54) reducing the width of an individual conductor and thus the cross-sectional area of the magnetic flux density on the conductor surface. The sub-stripe-lines are connected together at the inductor conductor ends (45, 46). In order to cancel out the eddy current loss of a closed loop the order of the sub-stripe-lines is reversed or changed at a specific point (59) between the fascicle ends.
