Unifier GGBLA.01.A Loop Antenna Taoglas Unifier GGBLA.01.A Loop Antenna is a 3.2 x 1.6 x 0.5mm omni-directional ceramic SMD antenna for GPS/GLONASS/BEIDOU applications. As part of the Unifier antenna series, the GGBLA.01.A antenna's wide bandwidth enables stable, high efficiency reception on all three GPS, Glonass, and Beidou bands from 1555MHz to 1602MHz. The GGBLA.01.A achieves efficiencies of 64% to 85%. With a peak gain of 3.3dBi, the GGBLA.01.A Loop Antenna's gain performance places it in range of much larger 15mm to 18mm patch antennas. The size and performance characteristics of the GGBLA.01.A Loop Antenna make it especially well-suited for small-sized automotive navigation or position tracking systems and hand-held devices when GNSS function is needed.
