Antenna & Wave PropagationAntenna Arrays

The array factor of an antenna array primarily depends on element?

  • APositions and relative excitation amplitudes/phases
  • BConductor color
  • CMechanical weight only
  • DDielectric breakdown voltage only
Report an error
Correct Answer: A. Positions and relative excitation amplitudes/phases
Explanation: Array factor is determined by the geometry and relative complex excitation of the elements, separate from the individual element pattern.
Reference: Standard antenna and wave propagation: antenna arrays
