Design of a Slotted Substrate Integrated Waveguide Antenna using a Metasurface

In this paper, the use of a metasurface to improve the radiation properties of a Substrate Integrated Waveguide based slotted antenna is proposed. The design process of a 8 slot antenna covered by a metasurface and following a Chebyshev distribution is presented. We will compare the performance of this antenna and of a conventional one and demonstrate the improvement in the radiation performance that can be achieved without affecting its bandwidth.
