A Novel Printed Fractal Log-Periodic Dipole Antenna

Abstract

This paper presents the research on a novel miniaturized printed log-periodic antenna with fractal tree structure for operation in a broadband of 0.4 GHz-2GHz. The antenna is designed and simulated with the application of CST MICROWAVE STUDIO®software based on the Finite Integral Method. The simulation results show that the antenna achieves the necessary lateral size reduction to 61% of the normal log-periodic antenna, while keeping its radiation characteristics nearly constant.
