Abstract

Defense modern communication systems have recently required more complicated design and operating features. Smaller devices can be combined for different communication systems and implemented in one user's device board. Furthermore, the cost of structure production should be kept to a minimum. The absorber of these devices should be compact, light, operate in various frequency bands, and/or be broadband to meet part of that request. There are numerous research strategies for achieving this goal, one of which is the use of fractal geometries for absorber element shape. Many fractal forms have been proposed for such applications in recent years, and the constructed antennas have greatly improved. In addition of using fractal the use of Metamaterial (MMT) with negative permittivity and permeability values to design absorber and get a high absorption rate is recently investigated. The advantages of employing fractal-based MMT arrangement to create radio and microwave absorbers were discovered in this paper. This paper provides a good review of the different fractal geometry types that are used to design MMT absorbers. This study's objective is to showcase the most recent discoveries and academic studies related to the subjects mentioned above.
