Design and Analysis of Metamaterial Waveguide Antenna for Broadband Applications

Abstract

Present paper proposes an antenna-based metamaterial waveguide for broadband applications which works on 7.8 GHz for its return loss. Analysis has been developed X band waveguide which covers coupled split ring resonator having broadside version and C-band waveguide to excite the metamaterial structure as a waveguide to coaxial transition. This structure is numerically analyzed using commercial software CST studio tool. Structure is simulated on dielectric substrate RT duroid with dielectric constant 2.33. Obtained return loss and VSWR are −35 dB and 1.2, respectively. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
