Ground plane size for M20057-1 antenna module
The eval board has a 80mm wide grounding area.  Does a smaller ground plan affect the efficiency of the antenna?  I would like to have 5-10mm on each side of the antenna.

Hi Bob,

The width of the ground plane is very important for the M20057-1 antenna module. 80mm ground plane width would allow the antena to perform optimally. As the ground plane width decreases the efficiency of the antenna also decreases.
