Anteral Log Periodic Antenna

Logp antennas

  • Broadband bandwidth from 500 MHz up to 18GHz.
  • 7 dB typical average gain.
  • Lightweight.
  • Optimized high performance design according costumer specifications.


Anteral’s Log-periodic Antenna is a dipole array antenna which exhibits extremely broadband bandwidth with frequency independent properties in its design band. Dipoles are printed on a RF dielectric substrate making this antenna of light weight but robust design.


The Log-periodic Antenna is useful for any application where linearly polarized radiation, moderate gain and stable impedance and radiation pattern performance over a wide bandwidth is required. Popular applications include terrestrial television, EMC measurement, wireless communications and electronic warfare.
