Radiation characteristic in 5150-5350MHz band
Main antenna
- Notebook operation mode
- Tablet operation mode
Note1) The measurement was performed at 4 frequencies (5150, 5200, 5250, 5350MHz).
Note2) The maximum antenna gain was found around 340 degree angle from measuring apparatus in
Horizontal polarization at the low frequency (5150MHz) of Notebook operation mode.
