Multiband Triangular Fractal Antenna for Mobile Communications

The design of 2.45 GHz-Triangular fractal antenna using fractal geometry has been proposed in this paper. The Ansoft HFSS software has been used to simulate the antenna and observed that increase in iterations led to improvement is VSWR & return losses. It has also been observed that with increase in the number of iterations the bandwidth of the antenna increases & on second and third iterations the antenna starts showing the multiband behavior which is very much demanded in cellular communications. The obtained results have also been validated using HP810B network analyzer. The simulated and experimental results are found to in good agreement.
