Claim 0:
1. A dual polarization log-periodic antenna apparatus comprising:
a log-periodic antenna; and
a conical reflector arranged below the log-periodic antenna,
wherein the log-periodic antenna is configured to transmit a plurality of radio waves;, the conical reflector is configured to reflect the radio waves transmitted by the log-periodic antenna,
wherein the log-periodic antenna comprises:
a printed circuit board, the conical reflector arranged below the printed circuit board;
a first planar log-periodic antenna structure formed on the printed circuit board;
a second planar log-periodic antenna structure formed on the printed circuit board;
a third planar log-periodic antenna structure formed on the printed circuit board and electrically connected to the first planar log-periodic antenna structure; and
a fourth planar log-periodic antenna structure formed on the printed circuit board and electrically connected to the second planar log-periodic antenna structure.
