Figure 7.3. Non-Optimal Layout Examples
The width of the GND plane to the sides the module will impact the efficiency of the on-board chip antenna. To achieve optimal per-
formance, a GND plane width of 50 mm is recommended. See Figure 4.1 Typical 2D Antenna Radiation Patterns and Efficiency on
page 21 for reference.
