N-Way Microwave Power Divider Using Two-Dimensional Meta-Materials Author:

Abstract: An N-way power divider based upon meta-materials is presented. The divider essentially comprises a two-dimensional mosaic of both right-handed and left-handed four-port unit cells. The power divider is square shaped and this allows ease of integration with amplifiers. The feasibility of the proposed divided is demonstrated by the simulation of a 20-way divider operating at 1 GHz. The radial power divider is well known for its ability to realise N-way power division for large values of N. This ability stems from the circular symmetry of the radial waveguide, but careful design is required to ensure spurious modes are not excited [1]. In recent years, meta-materials that display left-handed propagation behaviour hav
