DESIGN AND SIMULATION OF MULTIBAND CHAUCER FRACTAL PATCH ANTENNA LOADED WITH DUMBBELL

This paper presents design and simulation of multiband Chaucer fractal patch antenna loaded with dumbbell shaped structure simulated and fabricated on FR4 material having relative permittivity 4.4 and thickness 1.6 mm. The operating frequency is in the ISM band. The antenna resonates at 2.4 GHz. Here we will find various performance characteristics like return loss, impedance, gain, and bandwidth and directivity at resonant frequencies. The antenna structures will be studied using Ansoft High Frequency Structure Simulation (HFSS) based on Method of Moments (MoM). The results obtained indicate that there is a fair value of return loss, gain, and bandwidth and directivity at all resonant frequencies.
