2.1 Radiation Pattern

Figure 2-1 shows how to relate the radiation patterns in this application note to the orientation of the antenna.

Note that the size of the ground plane will affect the radiation pattern. Thus, implementing this antenna on a board with a different size and shape of the ground plane will most likely affect the radiation pattern.
