we have given details on the Microstrip antenna with metamaterial absorber structures. How the metamaterial structures are works and their absorbance capability of different structures with their different characteristics on single band, multiband structures, and unit cells are consist of dielectric of FR-4 and how they are affecting the microstrip antenna’s results for overall improvements like keeping radiation pattern preserved and help to increase gain, directivity and also, the reduction in the Radar Cross Section by using this metamaterial structures. And also given the comparative analyses of all three-metamaterial structure combined with simple rectangular microstrip antennas.
