Antenna offers enhanced positioning for GNSS devices

At the Mobile World Conference in Barcelona, imec has unveiled a multi-frequency antenna for Global Navigation Satellite Systems (GNSS) that can simultaneously receive all GPS, GLONASS and GALILEO bands.

Developed in collaboration with Septentrio, a manufacturer of high end GNSS receivers, the antenna can be integrated in multi-frequency handheld GNSS devices for high precision location applications up to 1cm. Integrating imec's GNSS antenna with Septentrio's GNSS RF front-end, the device 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. What's more, imec says it is small enough to fit in a handheld surveyor device.
