Reconfigurable reflectarray antenna is one of the options proposed in this work that can be used as an active antenna in order to allow the change in the frequency of operation and hence, the dynamic phase control of resonant elements. The capability of realizing frequency tuning using slots embedded into patch elements is presented. In this study, the change in resonant frequency and phase distribution has been investigated using frequency tuning strategy within X-band frequency range. This further enhances the feasibility of reflectarray antenna of realizing electronic beam scanning. The results obtained from commercially available CST computer model demonstrate that the energy reflected with a minimum simulated reflection loss of -0.6233 dB Moreover, the maximum attainable phase range of 4.922 rad allows the beam to be scanned up to an angle of 26 degrees. Analysis of the frequency tuning capability of resonant elements using CST computer software will be integrated with measurement using waveguide simulator to show the reliability of the change in frequency and phase distribution.
