In the design of this IRS, FR-4 is chosen as the dielectric material, and copper is used to create both the reflecting elements and the ground plane. Phase shifting characteristic is achieved by using varactor diodes on the designed two-dimensional surface. In order to test the behaviour of the IRS, a horn antenna is also designed to be used as a source with the ANSYS HFSS (v21) program. The obtained results are presented in terms of return loss and gain values of the IRS. The results of the simulations reveal that the phase angles of the incoming signals can be adjusted as expected by changing the capacity values of the varactor diodes modelled by their equivalent circuits on the IRS.eninfo:eu-repo/semantics/openAccessArticle10.28948/ngumuh.1422104
