Most of panel antenna is used in point to point, and some case could be used in point to multi point. Basically, if people use panel antenna, then the eradiation will be limited in a single direction, however in Horizontal or Vertical field.
The eradiation angle could be changed to follow the gain difference. Normally the angle will be getting to smaller to follow the gain getting to bigger. Even the vertical angle will be bigger then Horizontal angel when gain is really to be big (In vertical antenna).
