Design and Performance Improvement of Broad-Beam Microstrip Reflectarray

— This paper presents the design and the effectiveness of reducing the unit cell size of microstrip reflectarray which is duplicated the same radiating aperture as quadratic backscatter. A reflectarrays with variable element sizes and reduced grid spacing have been designed at 10 GHz. For a given number of elements, it is shown that increased gain can be attainted for reduced unit cell size with no significant change in array size.
