In this paper, transmission line cloaking for arbitrary objects with different dimensions is presented. Double-sided parallel-strip line network causes electromagnetic waves to be coupled to the network surrounding the object and pass them across it without forward and backward scattering. Using of these unloaded transmission lines makes the simplicity of the structure feasible. Achieving a broadband cloaking condition is the other advantages of the proposed structure. Large object cloaking is provided by the using of a new structure which has an empty space in the center of similar previous structures. Simulation results demonstrate the quality of cloaking for different dimensions in conventional and proposed structures.
