This paper reports on the performance comparison of different structures of reflectarray resonant elements operating in X-band frequency range. A thorough investigation has been carried out in terms of reflecting area, surface current density, reflection loss, 10% bandwidth, reflection phase and Figure of Merit (FoM). Predicted results based on Finite Integral Method (FIM) demonstrate that rectangular patch element with widest reflecting area of 105.46mm2 and surface current density of 162A/m is shown to offer minimum reflection loss and static phase range of 0.23dB and 120° respectively, whereas triangular loop with a smallest reflecting area of 7.46mm2 and surface current density of 3925A/m exhibits maximum reflection loss and static phase range of 3.90dB and 190°. Moreover it has been shown that FoM value increases with an increase in static phase range performance.
