Which of the following is an advantage of a log-periodic antenna?

  1. Wide bandwidthRespuesta correcta
  2. Higher gain per element than a Yagi antenna
  3. Harmonic suppression
  4. Polarization diversity

Explicación

In a log-periodic array successively scaled elements take over as the frequency changes, giving nearly constant gain, pattern and impedance across a wide frequency range. Its gain per element is lower than a Yagi's, not higher, since only a few elements are active at any one frequency.
