The accuracy of the power gain and the effective area of the horn antenna are of primary importance for the class of the EMF standard in which the antenna is applied. Horn antenna work above 1 GHz frequency range. Horn antennas are usually fed from a waveguide; the simplest “horn antenna”is an open end of a waveguide. Possible estimation errors and measurements are discussed in this chapter.
