A formula for the optimal relation between the width of a planar conductor ( w 0 ), the total width of parallel straight planar conductors ( W ), and the number of the parallel conductors ( N ) for the minimum ohmic resistance is presented. The formula is verified for the frequency range between 2 and 27.12 MHz according to N by using the finite element method. By experimentation, it is also shown that the proposed formula can be applied to design low‐loss circular planar coils.
