In this paper, the authors deal with the development of printed Log-Periodic Dipole Array (LPDA) antenna in reduced size by applying fractal Koch geometry structure. The proposed printed LPDA fractal Koch antennas which are deployed on FR4 epoxy dielectric substrates with the thickness of 1.6mm and relative permittivity of 4.3 are designed to have working bandwidth from 1.5GHz to 3GHz to cover some frequency bands of wireless communication. Some basic properties of antenna are analyzed numerically related to the physical parameters and its iterations in order to have optimum performance design.
