Antenna Parameters with Body TSL

General Antenna Parameters and Design

      Electrical Delay (one direction)                                                  1.154 ns


After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can be measured.

The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the
second arm of the dipole. The antenna is therefore short—circuited for DC—signals. On some of the dipoles, small end caps
are added to the dipole arms in order to improve matching when loaded according to the position as explained in the
"Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still
according to the Standard.
No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the
feedpoint may be damaged.

     According to the above description, this device was tested by the manufacturer to determine the
     SAR sensor triggering distances for the rear and bottom edge of the device. The measured power
     state within ±5mm of the triggering points (or until touching the phantom) is included for rear and
     each applicable edge.

     To ensure all production units are compliant it is necessary to test SAR at a distance 1mm less
     than the smallest distance from the device and SAR phantom with the device at maximum output
     power without power reduction.

     We tested the power and got the different proximity sensor triggering distances for rear and bottom
     edge. But the manufacturer has declared 16mm is the most conservative triggering distance for
     main antenna. So base on the most conservative triggering distance of 16mm, additional SAR
     measurements were required at 15mm from the highest SAR position between rear and bottom
     edge of main antenna.

The influence of table tilt angles to proximity sensor triggering is determined by positioning each
edge that contains a transmitting antenna, perpendicular to the flat phantom, at the smallest sensor
triggering test distance by rotating the device around the edge next to the phantom in ≤ 10°
increments until the tablet is ±45°or more from the vertical position at 0°.

                          The bottom edge evaluation for main antenna
Based on the above evaluation, we come to the conclusion that the sensor triggering is not released
and normal maximum output power is not restored within the ±45°range at the smallest sensor
triggering test distance declared by manufacturer.
