Log Periodic Dipole Array LPDA antennas are directional active broadband antennas that are the ideal solution for interference tracking site surveying and most general RF and EMC analysis applications due to their unique dipole elements positioned along the antenna axis in a triangular shape. The shape of a log-periodic antenna resembles that of a Yagi-Uda antenna but is composed of a coplanar array to achieve a wider bandwidth. NSI-MI Technologies Linear Polarized Log-Periodic Antennas ANT-LPA are dipole arrays designed to have nearly constant gain and input impedance over a broad frequency range.

The Yagi-Uda antenna is mostly used for domestic purpose. However for commercial purpose and to tune over a range of frequencies we need to have another antenna known as the Log-periodic antenna. Biconical antennas are essential for lower frequency EMI electromagnetic interference testing for EMC applications including emissions testing.
