Developed under the European Community’s Seventh Framework Programme project HANDHELD, the compact antenna can be integrated in multi-frequency handheld GNSS devices for high precision location applications up to 1 centimeter.

The announcement was made at the Mobile World Conference in Barcelona this week.

The compact antenna integrates Imec’s innovative GNSS antenna and Septentrio’s GNSS RF front-end. Imec’s antenna design satisfies the requirements for the high-accuracy GNSS market while remaining small enough to fit in a handheld surveyor device. It has desired uniform gain and phase coverage over the complete upper hemisphere with strong suppression of unwanted reflected signals below or in the vicinity of the GNSS receiver.

The GNSS RF front-end is characterized by a out-of-band interference rejection to avoid notably device self-interference with other radiation sources such as Bluetooth and WLAN radios, as well as other ambient intentional and non-intentional interference. The compact multi-frequency antenna is a perfect companion of Septentrio’s compact and low power AsteRx-m™ receiver, a credit card-sized dual frequency GNSS receiver that provides centimeter accuracy at less than 500mW power consumption, by far the lowest power consumption in the professional GNSS market.

The research leading to these results has received funding from the European Union Framework Programme.
