Antennas
The antennas transmit and receive the radio signal generated by the RF module and
receive the backscatter signal from the tag.
The IT2200 Reader System with Multimode Capability uses either a pair of AA3152
or AA3153 Antennas for bistatic configuration or a single AA3152 or AA3153
Antenna for monostatic configuration depending on the installation. The AA3152
Antennas are used in overhead installations and AA3153 Antennas are used in side-
mount installations.
Ideally, in any RFID system, the tag to be read is oriented such that the polarization of
its internal antenna is aligned favorably with the polarization of the system antenna.
Figure 3-6 illustrates the linear polarization of an antenna and tag.

AA3152 Universal Toll Antenna
The IT2200 Reader System with Multimode Capability uses either one or two
AA3152 Universal Toll Antennas (UTA) for overhead and gantry plaza installations.
Functions
In a monostatic configuration, the AA3152 UTA acts as the downlink antenna
transmitting signals to the tag, and also acts as the uplink antenna receiving signals
from a vehicle tag. In a bistatic configuration, an AA3152 UTA acts as the downlink
antenna transmitting signals to the tag, and another AA3152 UTA acts as the uplink
antenna receiving signals from a vehicle tag.
