4 Typical Antenna Configuration (Gate Antenna with two Antennas)

The standard configuration of a gate with three-dimensional tag orientation consists of one antenna

ID ISC.ANT1700/740 Type A with reader and multiplexer and one antenna ID ISC.ANT1700740

Type 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.

4.1 Project Notes

The antenna configuration as described allows detection of a tag moving horizontally through the

capture 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 capture area of the antennas is shown in the sketch below.

Fig. 8: Capture area and tag orientation

Notes:

Note that the entire capture area of the antenna 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 capture area.

If multiple gates are arranged with short distances between each other, these will mutually

interfere with each other. The Readers for the respective gates must then be synchronized.
