Abstract: A transformer (100, 100′) is disclosed, comprising a first conducting element (110) having a first lobed portion (114) arranged to form a first plurality of lobes (116); and a second conducting element (120) having a second lobed portion (124) arranged to form a second plurality of lobes (126); wherein said first lobed portion (114) overlaps said second lobed portion (124) to define a plurality of enclosed areas (130). The transformer is adapted for applications requiring an autotransformer having a weak, negative magnetic coupling coefficient.
