log-periodic antenna[′läg ‚pir·ē¦ad·ik an′ten·ə]
A broad-band antenna which consists of a sheet of metal with two wedge-shaped cutouts, each with teeth cut into its radii along circular arcs; characteristics are repeated at a number of frequencies that are equally spaced on a logarithmic scale.
a type of a frequency-independent antenna with periodic repetition of the ratios of the characteristic dimensions of the adjoining components. The repetition obeys a logarithmic law in such a way that the ratio between the wavelength of the electromagnetic oscillations being radiated and the characteristic dimensions of the excited part of the antenna remains virtually constant over a wide frequency range.
