Effect of Measurement Distance on Gain Calibration of Pyramidal Horn Antenna
IEICE Transactions on Communications, 2010 Numerical simulations of the gain and phase center measurements for a pyramidal horn antenna are carried out. The electromagnetic simulation is based on the finite integration method. The gain of horn antennas varies with the distance between their apertures, even if the antennas satisfy the far-field criterion.
