Antenova antenna achieves centimetre accuracy

Antenna maker Antenova is shipping its latest positioning antenna – Raptor – which achieves accuracy in the GNSS bands that lets it pinpoint location to within centimetres.
The Raptor is an embedded antenna for positioning applications that require accuracy. In particular, it is suitable for emerging applications with autonomous vehicles, drones and other mobile devices where its positioning capability can, for example, indicate which side of the road a vehicle is on, something that has not generally been possible with previous GNSS devices.
The antenna will also be useful for applications in tracking, surveying and mapping.
It requires a corresponding high precision GNSS receiver module; these are also recently available on the market to connect the Raptor antenna in a complete RF system.
The antenna operates in the 1200 and 1600MHz GNSS satellite bands and is suitable for all global public constellations – GPS, Glonass, Galileo and Beidou. It supports the L2 1200MHz band in addition to the existing L1 and L5 bands.
It is a single feed antenna in compact SMD form, measuring 16.0 by 8.0 by 1.7mm, making it a practical choice for small electronic designs such as wearables and portable devices where space on the PCB may be restricted.
“We are seeing a lot of interest in this antenna,” said Colin Newman, CEO of Antenova. “Raptor provides the high performance of a much larger ceramic patch antenna, but in an ultra-low profile size which means designers can create very small devices that will pinpoint location very accurately.”
The addition of the L2 frequency band combines multi-band satellite signal reception and GNSS correction data. These help to mitigate position errors, improving accuracy, especially in urban areas.
Like the UK company’s other SMD antennas, the Raptor is designed according to its philosophy of design for integration, meaning it has been designed to fit easily into a PCB, alongside other components. Antenova specialises in the design of SMD antennas and also provides integration and testing services.
The Raptor antenna, part no SR4G053, is supplied in tape and reel.
