5 Typical Antenna Configuration (Gate Antenna with two Antennas)
The standard configuration of a gate with three-dimensional tag orientation consists of one
ID ISC.ANT1690/600-A with reader and multiplexer and one ID ISC.ANT1690/600-B. If a tag
moves, at horizontal line, through the gate, it can be read at least once. This ensures high reliability
of the antenna system.
5.1 Project Notes
The antenna configuration as described allows detection of a tag moving at a horizontal line,
through the reading area of the gate. The tag orientation is non-critical. The tags are detected
along a horizontal axis of motion in certain regions within the antennas. The area of detection
depends on the tag orientation.
The size of the three-dimensional reading area of the antennas is shown in the sketch below.
Fig. 8: Capture area and tag orientation
Notes:
Note that the entire reading area of the antenna gate is larger than the three-dimensional
area shown in the drawing. This means there are tag orientations in which the tag can be
detected outside the reading area.
If multiple gates are arranged with short distances between each other, these will mutually
interfere with each other. In this case, the readers for the individual gates have to be
synchronized.
