11.2.2 Special antenna construction
In addition to shielding the antennas to conform with national regulations, special antenna
constructions can be used to achieve compensation of the magnetic field by means of opposing
field directions. This has been tested by FEIG ELECTRONIC GmbH for various antenna
constructions and verified in a testing laboratory.
The prerequisite for this is that the antennas be constructed exactly as described. The antennas
must be connected to an ID ISC.ANT.PS Power Splitter. To ensure that the complete system stays
within the national RF and EMC limits, this must be verified by the system integrator.
Construct the antennas as follows:
Table 4: Construction with two ID ISC.ANT800/600-DA antennas
- The two antennas must be mounted directly next
to each other and in the same plane
- The two tuners (openings) of the antennas must
face out (right and left) and point in one direction.
- Antenna separation (corners) 1cm.
