Radiation patterns
Radiation patternsFarfield radiation patterns can be specified as cuts in spherical (Theta, Phi or Bank Angle) or UV coordinates. Up to 1441 points are allowed in any one cut and any number of cuts of the same type may be computed sequentially. Output examples are shown here.
Nearfield radiation patterns can also be computed.
Nearfield radiation patterns can be computed as cuts in spherical (Theta or Phi) at a fixed radius or they can be computed in planar coordinates at a fixed minimum range. Up to 1441 points are allowed in any one cut and any number of cuts of the same type may be computed sequentially.
An example of a monopole on a KC-135 aircraft (Figure 1) at a distance of 780 m is shown in Figure 2.
