Figure 29. Gain of the FZP and hyperbolic lenses at E-plane for focal distances of 2 mm and 8 mm. Gain is stated in
one direction (Tx or Rx side). For Radar Loop Gain (RLG) the values will be doubled.
5.3 FZP Lens Design
The FZP lens characterized in the previous chapters was made of ABS plastic. If other materials are to
be used or if another focal point distance is needed, the dimensions of the FZP lens should be altered.
In Figure 30, a detailed description of an FZP lens is shown, the radius and thickness for each step can
be calculated by equations below:
