Abstract UWB application increases day-by-day along with various applications. As the communication is mostly dependent on wireless based, so a suitable antenna design is a major challenge for the researchers. In this paper we’ve taken an attempt to partially meet the challenge. The antenna is microstrip type based on Fractal Geometry. Initially the fractal antenna design has been made so its performance is in terms of bandwidth. Further the parameter of the antenna have been optimized to have better performance as compared to Un-optimized antenna. It shows output as shown in result section. Particle Swarm Optimization (PSO) which is a viable developmental improvement strategy is used for optimizing the proposed antenna. This method provides better results in the design of the antenna and it also analyzed the effect of the various design parameters like ground plane, feed line width, middle triangle radius. The improvement in the results has been included in the design. It is found to be suitable for UWB communication application. Keywords Microstrip antennas loss

1 Introduction The geometries of fractal antenna methodology approach become put sent by Nathen Cohen in 1995 [1]. The fractal antenna performs a most essential function in area of wireless communications due to its wideband and multi-band traits. Because

of this, the usage of microstrip fractal antenna geometry has been turnout to be latest topic for the researchers inside the global [2]. In remote correspondence wideband and multiband attributes is attractive to outline greater successful antennas. Fractal implies the uneven fragments, which might be the association of complex geometries which have the self-likeness systems [3]. Fractal geometries likewise diminish the overall length of antenna and it create different resonant bands [4]. The principle points of interest of fractal antennas are that they have low profile, linear and circular polarization, less fabrication cost, light weight [5]. Fractal antennas are composed by way of applying the boundless number of times an iterative calculation, for example, MRCM (Multiple Reduction Copy Machine) [2]. In the patch of fractal antenna geometry discontinuities presented to expand the radiation proficiency of antennas [6].
2 Proposed Design of Antenna The different stages to develop the antenna is shown in Fig. 1. At 1st stage the triangular patch is considered as shown in Fig. 1a. Next to it an equilateral triangle is integrated in
