7.4 Antenna Characteristics
The antenna is a standard monopole chip antenna. The radiation pattern is strongly dependent on the layout
of the mother board. Usually the gain is highest to the directions where there is most GND and weakest to the
opposite direction. Typically the total radiated efficiency is around 25% - 35%. The maximum gain is 0.5 dBi.
