PRINTED CIRCUIT BOARD FOR LOG-PERIODIC DIPOLE ARRAY ANTENNA AND INTEGRATED SYSTEM FOR THE SAME

摘要

Provided are a printed circuit board (PCB) for a log-periodic dipole array (LPDA) antenna installed in an airport, and an integrated system for an LPDA antenna including the same. In particular, the PCB for an LPDA antenna comprises first and second terminals connected to an LPDA antenna; a radio frequency (RF) transformer for matching impedance of the LPDA antenna; and passive elements having previously designed connection relations, wherein the first and second terminals are spaced apart from one another by a pre-set distance, disposed to be parallel, and connected to first and second line bodies forming the LPDA antenna, and one side of the RF transformer is connected to the first and second terminals and the other side of the RF transformer is connected to a signal analyzing unit analyzing a signal radiated from the LPDA antenna and a ground terminal.
