IsoLOG DF 16-20400 tracking antenna from Aaronia

Aaronia’s tracking antennas move up in frequency

  • Aaronia has expanded its IsoLOG series tracking antenna family with four new models to meet the demand for broadband signal-locating antennas up to 40 GHz.

3D RF Tracking antennas track RF positioning in three dimensions via a high-density, adaptable antenna array of up to 32 antennas to deliver azimuth and elevation information.

While the IsoLOG® 3D DF 160-8 and lIsoLOG® 3D DF 80-8 models cover a frequency range from 400 MHz to 8 GHz, and from 20 MHz to 20 GHz respectively, the two new tracking antennas offer a higher frequency range. The IsoLOG® DF 16-10180 offers a frequency range from 1 GHz to 18 GHz, while the IsoLOG® DF 16-20400 can target signals at frequencies from 2 GHz to 40 GHz.

Combined with the real-time direction-finding system, the IsoLOG® DF/3D DF antenna arrays enable detection and localization of most signals in the corresponding frequency range. In particular, even the shortest signal pulses, in the microsecond range, can be detected and localized.

According to Aaronia, this enables reliable signal suppression, particularly in the field of UWB (Ultra Wideband) communications or radar, which are generally invisible to most direction-finding systems. This is due to the high bandwidths of UWB signals, combined with extremely short pulse times. For example, the bandwidth of a UWB signal is at least 25% of the transmitter’s center frequency. A center frequency of 2 GHz has a bandwidth of 500 MHz. The minimum bandwidth of a UWB signal with a 4 GHz center frequency is therefore 1 GHz.

360-degree coverage is achieved without mechanical rotation of the antennas. This translates into extremely short tracking speeds (down to 8 μs). According to the German manufacturer, the wide frequency range covered, particularly by the IsoLOG® 3D DF 16-20400, eliminates the need for multiple antennas, saving space and reducing monitoring system costs.

By connecting several antenna sites in cascade, triangulation solutions can be created. Various RF fiber transmission links are also available. This makes it possible to cover long distances between the various sites of the monitoring system. This makes it possible to monitor radio signals over large areas.

IsoLOG® 3D DF antennas are integrated into an IP65-certified radome, which is both shockproof and heat-resistant.

The IsoLOG® 3D DF16-10180, IsoLOG® 3D DF16-20400 and the IsoLOG® DF16-10180 and IsoLOG® DF16-20400 versions are scheduled to be available from the third quarter of 2024.
