![]() ![]() ![]() The results show that The structure has peak absorption 99.7 % with 2GHz bandwidth. There is air gap exist between the absorber slot. It consists of a substrate layer as FR-4 layer of a thickness 1mm and PEC circle fractal loaded on it. The layout of the designed antenna is depicted in. In this paper, the unit cell of the proposed structure is based on Apollonian second iteration gasket fractal geometry to introduce an X-band (8-12_GHz) metamaterial absorber for radar military applications. The Apollonian gasket ultra-wideband fractal antenna with coplanar waveguide feed is analyzed over the frequency band from 3 GHz to 18 GHz 25. Because of their properties it used in many applications, one of its applications is to design a radar absorber. The Apollonian Gasket, and the methods used to produce them, are described in the excellent book Indra's Pearls - The Vision of Felix Klein by David Mumford, Caroline Series, and David Wright. The metamaterial (MM) tasks as a left-hand material with negative permittivity and permeability, which results in a low refractive index. The Apollonian Gasket Variations examples use an attractor based on a variation of the algorithm used to generate the Apollonian Gasket. As a result of their compactness throughout all frequency ranges, metamaterial-based absorbers are also discovered to be of significant interest. The symmetry transformation used in Apollonian Gasket 01 defines 4 transformations that scale/translate the original Apollonian Gasket into these 4 empty circular areas and a 5 th transformation that inverts the Apollonian Gasket in a circle centered at the origin with radius 1. because of their wide-ranging applications especially in military. In addition, there are 2 empty circular areas that are 0.33333 the size of the base fractal, with centers at 0.66666i and -0.66666i. In recent years, there are a lot of attentiveness in the study of absorbers. Metamaterial, Apollonian gasket, Absorber, radar Abstract ![]()
