Separate antennas are used to optimize the radio field for the application. In industrial applications, this permits a reliable radio link.

Antennas with multiple connections (dual or MIMO antennas)

Antennas with two connections combine two individual antennas, at 90° to each other, in a single antenna enclosure. With these antennas, two data streams can be transferred simultaneously thanks to the two different polarization levels. Depending on the alignment of the polarization levels, these antennas are referred to as dual-slant (rotated through +/-45°) or vertical-horizontal.

Antennas with three connections contain three individual emitters that can be combined in a single enclosure, either on different polarization levels (0°, +/-45°) or at a suitable distance from each other. The MIMO antennas can transmit or receive three data streams simultaneously using multiple path propagation.

Transmission of several data streams results in increased data throughput and simultaneously a more reliable data transfer.

Directional effect

The suitable antenna is selected first by means of the wireless field characteristic. A distinction is made between omnidirectional antennas and directional antennas.

Omnidirectional antennas

Omnidirectional antenna

With omnidirectional antennas, the radio field is emitted in every direction surrounding the antenna (horizontal opening angle: 360°), but it weakens as the distance increases. There is a concentration in the vertical direction which creates passive amplification of the radio field. Many omnidirectional antennas have extremely weak radiation directly below the antenna due to their type of construction. This property can be seen in the associated antenna diagram.

ANT795-4Mx

With these omnidirectional antennas, the radio field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. All antennas of this type have an opening angle of 30° in the vertical direction. They are directly mounted on the R-SMA or N connector of the SCALANCE W enclosure.

ANT795-4MA, ANT795-4MB, ANT795-4MC, ANT795-4MD and ANT795-4MX

The ANT795-4MA and ANT795-4MB antennas feature an additional joint and an R-SMA connector. ANT 795-4MA has an antenna gain of 3/5 dBi and degree of protection IP30, ANT795-4MB has an antenna gain of 2/3 dBi and degree of protection IP65. This makes them ideally suited for the SCALANCE W788 RJ45, W770 and W760 access points and the SCALANCE W748 RJ45, W730 and W720 client modules.

The ANT795-4MC and ANT 795-4MD antennas can be rotated around only one axis and feature an antenna gain of 3/5 dBi, N-Connect connectors and degree of protection IP65. They are used with the SCALANCE W788 M12 Access Points and the SCALANCE W748 M12 Client Modules.

The ANT795-4MX antenna can be rotated around only one axis and feature an antenna gain of 2 dBi, N-Connect connectors and degree of protection IP68/69K. It i used with the SCALANCE W788 M12 Access Points and the SCALANCE W748 M12 Client Modules. It is especially well suited for applications in the railway environment.

ANT792-6MN, ANT793-6MN and ANT795-6MP

With these omnidirectional antennas, the radio field is concentrated at 2.4 GHz (ANT792-6MN, ANT795-6MP) and/or 5 GHz (ANT793-6MN, ANT795-6MP) in the vertical plane of the antenna. The antennas have a gain of 5 dBi to 7 dBi.

N-Connect is used as the connection plug and can be connected to SCALANCE W over an antenna connection cable from the range of IWLAN cabling. All antennas are supplied with a mounting aid (metal bracket) that supports wall or mast mounting. The antennas are therefore ideally suited, for example, to providing radio coverage for a place that has a mast at its center on which they can be mounted.

ANT795-6MN, antenna mounting tool for ANT795-6MN

With this omnidirectional antenna, the radio field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. The antenna has a gain of 6 dBi and 8 dBi respectively.

N-Connect is used as connection plug. The antenna can be connected to SCALANCE W over an antenna connection cable from the IWLAN cabling systems range. The antenna characteristic is such that good transmission properties also exist directly above and below the antenna. It is designed for mounting on a control cabinet or roof, but it can also be mounted under a roof, making it suitable for the mobile units of an automated guided vehicle system, for example. The optional antenna mounting tool for ANT795-6MN can be used for installing under a roof.

ANT795-6MT

This antenna is an omnidirectional MIMO antenna with three QMA connections. The wireless field is concentrated at 2.4 GHz and 5 GHz in the vertical plane of the antenna. The antenna has a gain of 6 dBi.

The antenna characteristic is such that good transmission properties also exist directly above and below the antenna. It is designed for mounting on a roof or (together with the supplied mounting bracket) under a ceiling, and it is thus suitable, for example, for the mobile units of automated guided vehicle systems.

The ANT795-6MT is connected to the SCALANCE W-780/W740 Access Points via QMA/N-Connect male/female IWLAN adapter cables and the IWLAN flexible antenna connection cables in the relevant length and connector version.

Directional antennas

Directional antenna

With directional antennas, the radio field is emitted both in the horizontal and vertical plane in the range of the opening angle. It is concentrated in these areas and generates passive amplification.
Based on the opening angle, directional antennas are divided into sector or wide-angle antennas (opening angle > approx. 30°) and strongly directional antennas.
Directional antennas are ideally suited to wall or mast mounting. The supplied mounting aid is used for a targeted adjustment.
N-Connect is generally used as connection plug. The antenna can be connected to SCALANCE W over an antenna connection cable from the IWLAN cabling systems range.

ANT795-6DC, ANT793-6DG and ANT793-6DT

The radio field can be aligned at 2.4 GHz and 5 GHz using these sector antennas. Each has an antenna gain of 9 dBi.

Thanks to their characteristics, they are suitable, for example, for providing wireless coverage for an area in front of a wall.

The ANT795-6DC antenna is suitable for both frequency bands 2.4 and 5 GHz. It has an N-Connect connection. Together with a SCALANCE W780 or W770, two or three antennas of this type can also be used for covering multiple sectors.

ANT793-6DG is a dual-slant antenna with two N-Connect connections for the 5 GHz frequency band.

ANT793-6DT is a MIMO antenna with three QMA connections for the 5 GHz band.

ANT792-8DN, ANT793-8DP, ANT 793-8DJ, ANT793-8DK and ANT793-8DL

These strongly directional antennas enable genuine amplification of the radio field. The radio field is concentrated in a narrow cone due to the narrow opening angle. High passive gains and long ranges are therefore achieved.

Due to the high passive gain, the antennas are ideally suited to bridging large distances.

The ANT792-8DN antenna is suitable for the 2.4 GHz frequency band and has an antenna gain of 14 dBi.

ANT793-8DP is an antenna with a high gain (13.5 dBi) in a compact enclosure. It is suitable for the frequency band from 4.9 to 5.35 GHz and therefore preferably for applications in Japan.

ANT793-8DJ (18 dBi) and ANT793-8DK (23 dBi) are powerful bidirectional antennas with vertical-horizontal polarization. They each have two N-Connect connections.

ANT793-8DL is also a powerful bidirectional antenna (14 dBi) with vertical-horizontal polarization and two N-Connect terminals. Thanks to its design, it is especially suitable for space-saving mounting on a railway line and in tunnels. In contrast to the omnidirectional rod antennas from the SCALANCE portfolio, this antenna transmits in the direction of the rod.
