ABSTRACT

In this paper, the main aim is to do the simulation of a fractal multiband antenna with circular split ring resonator and to analyze various factors like gain, directivity, return loss, radiation intensity for the frequency of 4-5 GHz. The simulation of fractal multiband antenna is carried out in ANSYS HFSS v2021. Results like return loss, radiation pattern, 3D polar plot, sidelobe level, beamwidth, radiated power, accepted power have been obtained using HFSS v2021. This research on fractal multiband antenna with circular split ring resonator gives a great view on how it can be designed and used at 4.8GHz frequency has a peak gain of 2.38dB .The scope of the proposed innovation extends within a fractal multiband antenna with square split ring resonator. The applications of the designed antenna have been discussed in the future scope.  The main advantage of combining a fractal Minkowski antenna with a circular split ring resonator (CSRR) is the ability to achieve multiband operation with a compact antenna design. The CSRR structure adds a resonant property, which further enhances the antenna's frequency range.
