A hexagonal surface filling coil tiling has been designed and manufactured in a flexible Polyimide foil, featuring additional overlap loops on all six tips of a hexagon. The loops serve the purpose of decoupling the next neighboring coils. The immediate neighbor coils are decoupled by overlaps along their edges. The single identical coils are staggered with respect to each other to form an almost arbitrary large phased array. The respective coupling between the single coils is -20 dB or better, even if bent at a radius of 15 cm along an arbitrary in-plane direction.
