4.3 Antenna configurations
Antenna spacing with portal configuration
In the portal configuration, multiple antennas are connected to one reader. In this case, the
antennas must not exceed the maximum distance to one another.

B Pointing at each other
Portal spacing of up to 10 m is possible. The probability of a read must be checked.

Read and write range

The read/write range between the reader/antenna and the transponder is influenced by the
following factors:
Table 4- 3
Factors
Transmit power of the reader
Transponder size and design
Absorption factor of the materials
Manufacturing quality of the tran-
sponders

Description
The higher the transmit power of the reader, the larger the
reading range.
The larger the transponder antenna, the larger the power
input area and therefore the larger the reading range.
The higher the absorption of the surrounding material, the
smaller the reading range.
The better the transponder has been matched to the oper-
ating frequencies during manufacturing, the greater the
reading range.
