Gain and Bandwidth Enhancement of a Metamaterial Loaded Antipodal Vivaldi Antenna Fed by Substrate Integrated Waveguide

This paper proposes a novel wideband, high-gain, compact Vivaldi antenna operating in the 14.7-20.5 GHz frequency range, where the antenna is fed by the substrate integrated waveguide (SIW). A Negative Index Metamaterial (NIM) has been designed, with its parameters extracted using MATLAB software. T...
