In this study, two phase-reconfigurable intelligent metasurface (envelope shaped and hexagonal-shaped) is introduced for precise self-adaptive control of the spatial electromagnetic reflection spectrum under agile frequency, operating in the microwave regime. The phase variation of these metasurface is targeted towards the band of 5.8 GHz for its wide range of applications. For the space control of intelligent phase reconfigurable metasur face system, self-adaptive multiple frequency agilities can be realized by a RIS control system by applyling proper voltage to individual varactor diodes to precisely tune the metasurface to efficiently redirect the beam at arbitrary azimuthal and elevation angle. This report is orgazined in three distinct sections. The article commences with a com prehensive literature review, which is then followed by the unit cell design and results related to the Envelope-shaped metasurface. The following part discusses the unit cell design and shows the results of the Hexagonal SRR. Finally, the report concludes with a comparison table of two of the designs.
