Abstract

A framework for the design and optimization of large dual-linear polarized,shaped-beam reflectarrays for advanced wireless communications is presented. Themethodology is based on the generalized intersection approach (IA) algorithm forboth phase-only synthesis (POS) and direct optimization of the reflectarray layout,as well as on the use of a method of moments in the spectral domain assuming localperiodicity. A thorough description of the design and optimization procedures isprovided. To demonstrate the capabilities of the proposed framework, two examplesare considered. The first example is a shaped-beam reflectarray for future 5Gbase stations working in the millimeter waveband, radiating a sectored-beampattern in azimuth and squared-cosecant pattern in elevation to provide constantpower in the coverage area. The second example is a very large contoured-beamreflectarray for direct-to-home (DTH) broadcasting based on real mission requirementswith Southern Asia coverage.
