Australia and New Zealand satellite coverage using a microstrip patch reflectarray

This paper presents the design of Ku‐band (12.25–12.75 GHz) dual‐polarized reflectarrays for Optus B1 satellites to obtain a contoured beam for Australia and New Zealand. The specified radiation pattern is synthesized using a phase‐only synthesis method based on the concept of intersection approach. Having determined the phasing data, single‐ and double‐layer reflectarrays are designed using variable‐size rectangular patches. The performances of the two reflectarrays are assessed by comparing their radiation patterns with the assumed pattern.
