The log-periodic antennas are very effectively useful to achieve large bandwidth. The planar log periodic antennas are having advantage of getting large bandwidth with careful design of impedance matching. The chebyshev impedance matching is one of the techniques to provide feed for the antenna followed by impedance matching. In this paper, the log-periodic antenna is designed with chebyshev impedance matching technique. The four arm log-periodic antenna is designed for the both linear and circular polarization. The antenna gives circular polarization when the 900 phase delay applied between the two dipoles.
