3.8 WT11u-A Antenna Specification
WT11u-A 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%.
