An Improved Method to Determine the Antenna Factor [PDF]
IEEE Transactions on Instrumentation and Measurement, 2005 We present an improved method to determine the antenna factor of three antennas. Instead of using a reflecting ground plane we use absorbers. Destructive interference between the direct beam and the residual reflected beam from the absorbers is avoided by splitting the measured frequency range in bands and changing the distance between the two antennas
