Meta Material are a bunch of human-made artificial materials, which are made up of an array of metal bars and rings. This category of materials against electromagnetic radiation exhibits interesting and unusual properties, such as a negative refractive index. The interesting properties of the materials are their widespread use in various fields of microwave, smart antennas, lenses, and so on. From the military point of view, it is also possible to use the meta material invisibility of self-birdies, such as the drones, missiles, and so on. The invisible coating design as well as the Shield design and the improvement of the shielding coefficient have been used for the safety of military systems and war rooms using forensic materials. In this paper, while describing the structure of the preamble, their properties in the face of electromagnetic waves are fully explained. A complete overview of the methods used in this category of antennae has been considered, which simulation results indicate an increase in parameters such as positioning, radiation power, bandwidth, and ultimately diminishing and multiplying in reference antennas.
