This paper presents an optimized design for Log-Periodic Dipole Array (LPDA) for GSM phase (I & II), WiFi, WiMAX, 3G mobile communication and Bluetooth bands. First, the LPDA is designed by evaluating length, diameter and spacing between dipole elements. The design is then optimized by using evolutionary technique called Particle Swarm Optimization (PSO). It is observed that the optimized design has improved gain and smaller size compared to the conventional LPDA design. Thus, the optimization technique provides a cost effective solution with improved characteristics for a broadband LPDA.
