Antenova reveals blade antenna at CES

At last week’s Consumer Electronics Show in Las Vegas, Antenova revealed a blade antenna and its latest reference design for a small but high performing on board device (OBDII).
The UK company developed the blade antenna for LTE Cat M1. LTE Cat M1 is an IoT-friendly version of LTE that provides enough bandwidth for data communications while maintaining a long battery life.
The blade antenna, part number SR4G055, measures 41.0 by 22.0 by 0.9mm and this OBDII unit operates in the 4G/LTE frequencies 698-894MHz and 1710-2155MHz.
The company’s designers have addressed the requirements for modern telematics in the design but created the unit in a way that allows users to design-in their own circuitry and be confident of gaining LTE Cat M1 certification. Antenova also offers Bluetooth and GNSS antennas that can be added and will co-exist happily on-board.
As well as OBDIIs, this design is also suitable for any LTE Cat M1or mobile application, for example trackers, portable devices, drones, network devices, smart metering, dashboard equipment and telematics.
“We are seeing strong demand for small LTE OBDs, and we know it can be tricky to create a successful design that will pass certification in a very small device where the space for the antenna is restricted,” said Antenova’s chief executive Colin Newman.
Antenova has created a version of its Refelector antenna that operates on and close to metal surfaces. The antenna, which is 1.6mm thick, is named Magna, part number SR4I051. This antenna is designed for industrial IoT markets and in particular lighting.
Reflector antennas are thinner than other antennas that would usually be mounted on a metal surface. They use two electrical layers, one isolated from the other, which enables an antenna to radiate on a metal surface or housing where it is usually extremely difficult for an antenna to operate.
The Magna antenna operates in the ISM frequencies at 868/915MHz and is designed for applications in industrial IoT and smart buildings. It comes with a cable and an Ipex connector and has an adhesive underside to fix it position inside a device.
“The new Magna antenna has the advantage of working over longer distances than can be achieved at 868/915MHz, so it can be used out of doors or in large warehouses,” said Newman. “It also operates on metal lighting and ceiling fittings. It’s perfect for very small light switches and energy saving applications.”
