摘要：The log-periodic antennas are very effectively useful to achieve large bandwidth. The planar logperiodicantennas are having advantage of getting large bandwidth with careful design of impedance matching. Thechebyshev impedance matching is one of the techniques to provide feed for the antenna followed by impedancematching. In This paper the log-periodic antenna is designed with chebyshev impedance matching technique. The fourarm log-periodic antenna is designed for the both linear and circular polarization. The antenna gives circularpolarization when the 900 phase delay applied between the two dipoles. The antenna is operated at 3GHz gives the bandof operation up to k/ka band from 2GHz. The antenna is designed and simulated by using HFSS software, the VSWR,S11 and axial ratio plots are generated from 2GHz to 18GHz.
