This paper demonstrates the operation of a dual band fractal antenna. The geometry of the inverted fractal antenna are 90mm × 65mm which is imprinted on FR4 substrate material whose dielectric constant is 4.4 with a thickness of 1.6mm. The proposed antenna operates at dual band i.e., from 0.9GHz to 1.4GHz and 2.4GHz to 2.7GHz which is capable of operating as a reader antenna, GPS and also WiMAX applications. The proposed antenna is simulated and analyzed using HFSS software. The antenna has an acceptable gain with desired radiation pattern across these operating bands. Keywords: Co-planar waveguide feed, HFSS, WiMAX, RFID, Fractal I.INTRODUCTION The wireless communication between any two points is possible only by using antenna. Now a days, the ability to integrate more than one device into a single system is difficult due to their compact size and limited space. So, the modern antenna design requires dual or multiband operation, simple structure and easy integration. Microstrip patch antennas are suitable only for low impedance bandwidth applications. These are not suitable for present wireless communications. To defeat this issue we have to design a multiband antenna by utilizing the fractal geometry i.e. self-similar structure. The antenna with small size, light weight, low profile are required in mobile, wireless communications, global positioning system etc. The broadband remote known as WiMAX (Worldwide Interoperability for Microwave Access) which is dispersed an information transmission of 2.5GHz 2.69GHz / 3.4GHz-3.6GHz / 5.2GHz-5.8GHz. GPS uses two frequency bands i.e., 1.57GHz known as L1 band and 1.22GHz band known as L2 band. The term fractal implies broken or sporadic section that has a self-likeness in their geometrical structure [2]. These are the iterative structures which provides several resonating frequencies in a single element. So, fractal geometry is implemented design small and multiband antennas. Fractals are capable of operating with good performance at many different frequencies simultaneously. CPW feed is more suitable for compact wireless communication [3][4]. The main advantage of CPW feeding technique is that patch and ground are placed on same plane which reduces the fabrication cost. Here in this paper a dual band inverted L-shaped fractal antenna is designed for GPS, WLAN, WiMAX applications and also as a RFID reader antenna.

ABSTRACT:Antenna is device which is used to transmit and receive electromagnetic waves. It is important to have small antenna which can be useful for mobile applications. In order for antenna to be useful for mobile applications, it is necessary to have small size and antenna. Design and simulation has been carried out using HFSS simulation software. In this dissertation, slots have been cut on side of patch so as to obtain better characteristics; initially patch of length 30 mm is taken and analyzed using coaxial feed at (1, 13, 0).U slots cut in patch is having length of 6 mm and two mm wide. Two straight arms are surrounding it with dimensions of 1x 8 mm 2 . This u slot is repeated for four sides. . By cutting four u slots, antenna resonated at 4.6 GHz, 5.2 GHz and 7.4 GHz with return loss of -19.81 dB, -11.10 dB and -18.1 dB with bandwidth of 200 MHz, 100 MHz and 800 MHz Parametric analysis had been done in terms of antenna parameters like substrate change, feed length, dimensions of patch and feed point variation.

“…At low frequency, the antenna which is of a basic geometry shape (such as dipole and rectangular patch antenna) tends to be large and the antenna often operates at a specific band. For this reason, researchers have been trying to design several antennas by modifying their shape with various methods [1][2][3][4][5][6][7]. For example, D.H. Werner modified the antenna shape with the fractal geometry in order to develop the antenna for multi-band application [8].…”

This research presents a new technique which includes the principle of a Bezier curve and Particle Swarm Optimization (PSO) together, in order to design the planar dipole antenna for the two different targets. This technique can improve the characteristics of the antennas by modifying copper textures on the antennas with a Bezier curve. However, the time to process an algorithm will be increased due to the expansion of the solution space in optimization process. So as to solve this problem, the suitable initial parameters need to be set. Therefore this research initialized parameters with reference antenna parameters (a reference antenna operates on 2.4 GHz for IEEE 802.11 b/g/n WLAN standards) which resulted in the proposed designs, rapidly converted into the goals. The goal of the first design is to reduce the size of the antenna. As a result, the first antenna is reduced in the substrate size from areas of 5850 mm 2 to 2987 mm 2 (48.93% approximately) and can also operates at 2.4 GHz (2.37 GHz to 2.51 GHz). The antenna with dual band application is presented in the second design. The second antenna is operated at 2.4 GHz (2.40 GHz to 2.49 GHz) and 5 GHz (5.10 GHz to 5.45 GHz) for IEEE 802.11 a/b/g/n WLAN standards.
