N2 - In this letter, wideband scattering performance of a reflectarray composed of a log-periodic dipole array (LPDA) is designed and studied numerically and experimentally. The reflectarray is designed using method of moments. Numerical simulation demonstrates that a reflectarray composed of the LPDA is wideband because the LPDA works as a wideband reflectarray element due to its self-complementary structure. The reflectarray is fabricated using a three-dimensional printing technology, and its scattering performance is experimentally confirmed. Finally, it is shown that the 1-dB and 3-dB bandwidths of the designed reflectarray are 45% and 64%, respectively.
