Admotus Ceramic Antenna for L1 GNSS Signals

Antenova’s Admotus miniature antenna provides comparable performance to a small patch antenna on a small ground plane. The Admotus surface mount ceramic antenna is designed for connectivity on L1 GNSS signals on all constellations, including GPS-L1 at 1575.42 MHz; GLONASS L1, 1602 MHz; Galileo L1, 1575.42 MHz; BeiDou (B1); and QZSS.

This ceramic antenna has an ultra-low profile measuring 1.0 mm x 0.5 mm x 0.5 mm, requires a 7.0 mm x 15 mm clearance area, and performs well on small PCB sizes. The compact footprint supplies high efficiency of 53% across the L1 band. The Admotus offers a peak gain of 0.9 dBi with an average gain of -2.6 dB, a maximum return loss of -11.5 dB, and a maximum of VSWR 1.8:1.

The Admotus ceramic antenna is suitable for all GNSS positioning applications in the L1 band (1559 MHz to 1609 MHz), such as wearable devices for fitness and medical monitoring, small portable tracking devices used to track keys, pets, bikes, scooters, jewelry, and other valuable assets, UAVs/drones, agricultural robotics, and telematics devices, to name a few.

Admotus joins Silvai and Abdita in the Antenova product line of ceramic antennas. The Silvai antenna works for ISM bands, and the Abdita antenna works on all 2.4 GHz applications. A companion evaluation PCB is also available (SR4W089-EVB-1).
