MTI Wireless Edge, a developer of flat-panel antennas, has announced a new line of RFID reader antennas for tolling applications. The new antennas are built to sustain extremely harsh conditions, according to the company, and include high-gain linear antennas with a relatively narrow AZ beam (AZ is the azimuth, or the pointing angle of the antenna's beam). They are available for use in the 902 to 928 MHz and 865 to 870 MHz frequency bands, as well as 5.8 GHz, and include a range of models that vary in coverage area.
The MT – 243024/NH is a 14 dBi flat panel antenna that measures 550 millimeters by 650 millimeters by 40 millimeters (21.7 inches by 25.6 inches by 1.6 inches) and weighs 7 kilograms (15.4 pounds). The MT – 243023/NH is a 14.5 dBi flat panel antenna measuring 550 millimeters by 900 millimeters by 40 millimeters (21.7 inches by 35.4 inches by 1.6 inches) and weighing 9 kilograms (19.8 pounds). Both models feature a plastic radome and a base plate made of aluminum with a chemical conversion coating.
