We propose a flexible and robust scheme to create closed quasi-one dimensional guides for ultra-cold atoms through the dressing of hyperfine sub-levels of the atomic ground state. The dressing field is spatially modulated by inductive effects over a micro-engineered conducting loop, freeing the trapping region from leading wires in its proximity. We show that arrays of connected ring traps can also be created by carefully designing the shape of the conducting loop. We report on characteristics of the trap and mechanisms that limit the range of parameters available for experimental implementation, including non-adiabatic losses and heat dissipation by induced currents. We outline conditions to select appropriate parameters for operation of the trap with atom-chip technology.
