<p>The present invention relates to a log periodic antenna system of a cross type. The purpose of the present invention is to reduce the size of a log periodic antenna and cope with broadband. The log periodic antenna system of the cross type according to the present invention comprises: a first log periodic antenna and a second log periodic antenna which is crossly arranged with the first log periodic antenna. The first log periodic antenna comprises: 1-1 dipole radiation devices capable of transmitting and receiving a first polarized wave; and first dipole radiation devices having 1-2 dipole radiation devices. The second log periodic antenna transmits and receives the second polarized wave, and comprises: 2-1 dipole devices which are closed with the first dipole radiation devices; and second dipole radiation devices having 2-2 dipole radiation devices. At least one among the first dipole radiation devices of the first log periodic antenna and the second dipole radiation devices of the second log periodic antenna has a shape which is bent to a lower direction.</p> |
