Abstract
The bandwidth features of aperture-coupled reflectarrays are analyzed by varying the spacing between adjacent elements in the array grid. A bandwidth enlargement is obtained by reducing the reflectarray unit cell size. The wideband behavior is demonstrated through the comparison of phase curves as a function of the operating frequency for various lengths of the tuning stub. As further validation, the gain against frequency is calculated to compare bandwidth features of two 20 GHz reflectarray prototypes with different cell size.
