What is effective isotropic radiated power?

  • A.The power actually radiated by the antenna in all directions
  • B.The power an isotropic antenna would accept at its terminals
  • C.The power density measured at one kilometre from the antenna
  • D.Transmitter power multiplied by the antenna gain

Answer: D

EIRP is the product of the power delivered to the antenna and its gain relative to an isotropic radiator, so it states the power an isotropic source would need to produce the same field in the main beam. It is the quantity regulators limit, because it describes what a receiver in the beam actually experiences. Total radiated power is a different figure, smaller by the gain, and the other two options describe no standard quantity.
