A model for the enhanced giant magnetoimpedance (GMI) effect in field‐annealed Co‐based ribbon with a meander structure is developed. Three different kinds of ribbon are fabricated by a MEMS method and the field dependence of the GMI effect is measured at 10 MHz. Good agreement between theory and experiment shows the validity of this model. A larger change of inductance L in the meander structure results in the increasing of impedance Z and the enhanced GMI effect.
