Abstract :
The Friis transmission formula between two antennas is used to measure the gains of these antennas. Generally the gains obtained by the Friis formula at a finite distance are not the far-field gains because the far-field gain is defined to be a value at infinite distance. The gain at the finite distance is called as the near-field gain. To obtain the far-field gain from the near-field gain in measurement is an important topic [1].
