Results of theoretical and experimental investigations of full-metal slot reflectarray antennas with increased bandwidth are presented. Bandwidth increasing is achieved by means of certain sizes choice for each reflective element so that the phase-error minimum in a required frequency range would be created . Two prototypes - single-layer and two-layer - of K-band slot reflectarray antennas have been manufactured and tested. Effectiveness of the described designing routine is proved by experimental data: achieved bandwidth for the single-layer and two-layer structure is 25% and 32% respectively.
