7.4.2 Typical Radiation Pattern Plot (WGM110A)
Typical 3D radiation pattern plot for the Wizard Gecko WGM110A Module is shown in the figure below. Application layout and mechan-
ics in close proximity to the antenna have an effect on the antenna radiation pattern, antenna efficiency, and peak gain. Optimal PCB
size with regard to the effect on the antenna performance is indicated in Figure 5.3 Guideline For the Achievable Range vs. Ground
Plane Width for WGM110A on page 17. Typically peak gain is achieved in the direction pointing away from the largest ground plane.

7.4.3 Qualified Antenna Types (WGM110E)
This device has been designed to operate with antennas having a maximum gain of 2.14 dB (see table below). Antenna types not listed
in the table and/or antennas having a gain greater than 2.14 dB are strictly prohibited for use with this device. The required antenna
impedance is 50 Ω.
