Influence of Angle (Reference)
Install Antennas and RF Tags as parallel to each other as possible.
Communications are possible even when an Antenna and a RF Tag are mounted at an angle, but the
communications distance will be shortened. The relation between the angle and the communications
distance is shown below.
