Design of a Compact Fractal Dipole Antenna for GPS-GSM-based Tracking Applications

This paper presents a design of a compact fractal dipole antenna for GPS-GSM-based tracking applications, which is based on the fractal theory. The proposed antenna has of two arms-one iteration is used on one side of the fractal arms and two iterations are used in other side to match the dual band at two different frequencies. The antenna is designed to work at 900MHz (GSM) and 2.4 GHz (ISM), and its size is 79mmx21mmx1.6mm making it small sized. The simulator software package used for this simulation was the CST Studio Suite software, and from the simulation results for gain, return losses and radiation characteristics, it makes the designed antenna suitable for the tracking applications.
