A millimeter-wave (mmW) fully metallic crossover with six intersecting channels based on Maxwell fish-eye (MFE) lens is proposed. The quasi-MFE lens consists of an almost-parallel plate waveguide with a curved top plate and an array of uniform metallic posts loaded on the bottom plate. Six pairs of rectangular waveguides are added that surround the lens to form a six-channel crossover. The results show a performance of broadband and efficient crossing transmissions, indicating the application potential of the proposed crossover in the multichannel mmW systems.
