Antenna tuning combines the fixed inductance of the mobile device s built-in antenna
with electronically controlled capacitances; the Antenna-Tuning Circuit precisely controls tunable capacitors, such as ST s STPTIC series, to optimally match the resonant frequency of the antenna and the frequency band being used.
With the integrated directional antenna and high performance 150Mbps 11n radio, the AirMax5N/AirMax5N-ESD can reach long distance using the built-in antenna
. AirMax5N/AirMax5N-ESD is also equipped with R-SMA connector.
Using a built-in antenna
browser, users can scan through antenna directories and view 2D and 3D thumbnails of antenna patterns; patterns can be compared and customized for presentations.
