DESIGN OF MICROSTRIP ANTENNA USING FRACTAL GEOMETRY AND METAMATERIAL

The performance improvement which was achieved in rectangular patch antenna was made by the use of fractal geometry and Left-Handed Metamaterial (LHM). The two types of fractal geometry used are 1 iteration of Minkoweski and Koch separately, while the 2 iteration includes (a combination two types of Koch and Minkoweski). The S-Shape Split Ring Resonator (S-SRR) was used to ensure the Left-Handed Metamaterial (LHM), that's mean negative value of permeability and permittivity in the same frequency band. Finally a combination of the designed (fractal antenna and S-Shape SRR) were used together, and the effect of this combination on antenna performance were made. Implementation of fractal geometry leads to the area redaction by 30%, and the implementation of S-SRR leads to the bandwidth improvement by 4% compared to the rectangular patch antenna design. The used program for the antenna design and their performance is CST software (Computer Simulation Technology), CST STUDIO SUITE 2010.
