Observations on the performance of reflectarrays with reduced inter-element spacings

Several authors have described the use of reduced inter-element spacing as a means of improving the performance of reflectarray antennas. This paper discusses some additional aspects that complement their conclusions, and emphasizes some of the reasons for these improvements.
