This paper describes the design of a bifocal lens antenna for multibeam antennas (MBA) applications. The radiation characteristics of the bifocal lens antenna are presented with focus on scan loss, half power beamwidth and radiation patterns for different scanning angles. Additive manufacturing (AM) is used to 3D print the bifocal lens antenna. The advantages offered using 3D printing technology compared to conventional manufacturing techniques include a more flexible design capability, more costly efficient, less human interaction, less prototyping time and therefore faster product development cycle. The advantages of using transformation electromagnetics to develop a flat bifocal are also presented.
