Abstract

This paper presents our recent research progress in developing beam-steering reflectarrays and transmitarrays with a reduced number of elements. To achieve this objective, a hybrid design method that mixes different types of elements including microstrip patches and dielectric lenses into one aperture is developed. The advantage of this design method is that the total number of elements in the aperture can be reduced while promising beam-steering performance is maintained. To validate this hybrid design method, one reflectarray and one transmitarray are designed and simulated. The simulation results show good beam-steering performance with promising radiation patterns. As proof of concept, multiple passive prototypes were fabricated and measured as demonstrators. A good agreement between the simulation and measurement results is obtained. The present hybrid design method is scalable and can be extended to the design of active arrays.
