3.5 Antenna Specification
WT11i uses a monopole type on a chip antenna with maximum gain of 0.5 dBi. The radiation pattern and the
total radiated efficiency are dependent on the layout and any metal around the antenna has an effect on the
radiation characteristics. Typically the efficiency is 30 … 50%.
