Kathrein WideRange 40° PRO antenna

Long-Range UHF RFID Antenna for Vehicle Identification

High-gain, linearly polarized UHF RFID antenna with a focused 40° beamwidth, reading ranges up to 20 meters and IP67 protection for toll collection, vehicle identification and outdoor ITS applications.

The WideRange 40° PRO antenna from KATHREIN Solutions is designed for reliable UHF RFID identification over long distances, particularly in Intelligent Transportation Systems (ITS), electronic toll collection and automated vehicle identification.

With a reading range of up to 20 meters, high antenna gain and a 40° beamwidth in both horizontal and vertical directions, the antenna enables selective detection of RFID transponders in defined reading zones. Its linear polarization supports the reception of weak transponder signals, making it particularly suitable for identifying vehicles moving through RFID detection areas.

The antenna is available in two regional frequency variants: ETSI (865–868 MHz, 52010251) and FCC (902–928 MHz, 52010252).

Focused RFID Identification for Tolling and Traffic Applications

The WideRange 40° PRO combines long-range performance with directional RFID coverage. Its 40° beamwidth helps concentrate the reading area, supporting selective identification where multiple vehicles or tagged objects may be present.

Typical applications include:

• Electronic toll collection: RFID identification of tagged vehicles in free-flow tolling systems.

• Vehicle identification: Contactless recognition of cars, trucks and commercial fleets.

• Traffic enforcement: RFID-based vehicle identification within roadside monitoring infrastructure.

• Smart city infrastructure: Automated vehicle detection and identification at transportation facilities.

• Industrial RFID applications: Single-tag identification and bulk reading of multiple transponders.

The antenna's performance characteristics make it suitable for applications requiring defined reading zones, long-distance identification and reliable operation in outdoor environments.

High Antenna Gain and Robust Outdoor Design

The ETSI version delivers a typical antenna gain of 12.5 dBi, while the FCC version provides 13 dBi. Both variants feature linear polarization, a front-to-back ratio greater than 25 dB and a typical VSWR of 1.3:1.

The compact housing measures 480 × 480 × 25 mm and combines an aluminum chassis with a UV-resistant thermoplastic radome.

With IP67 protection and an operating temperature range from −40°C to +70°C, the antenna is suitable for permanent outdoor installations exposed to changing weather conditions.

An N-type female RF connector provides the interface to the RFID reader. For installation on poles and supporting structures, the antenna is compatible with KATHREIN's optional 3D mounting kit (52010262).

RFID Infrastructure for Intelligent Transportation Systems

The WideRange 40° PRO supports contactless identification in transportation environments where vehicles must be detected while moving through defined reading zones. Its combination of directional coverage, high antenna gain and weather-resistant construction makes it suitable for roadside RFID infrastructure.

In Brazil's Rodoanel Norte highway project, KATHREIN WideRange 40° PRO antennas are used alongside RRU 7800 RFID readers as part of a multi-lane free-flow tolling system implemented by ITS specialist Movyon. The system combines electronic vehicle identification with camera-based recognition, vehicle classification and automated transaction processing.
