Miniaturization of an artificial magnetic conductor with interdigital capacitances

This paper deals with a method to miniaturize an artificial magnetic conductor using interdigital capacitances. An artificial magnetic conductor with a resonance frequency of 2.66 GHz is designed and manufactured. The size of a unit cell is 15 χ 15 mm2 or 0.13 × 0.13 λο. The measurement result shows a resonance frequency slightly higher than the simulated one. Two circuit models are proposed to model the simulation and measured results.
