The GGBLA.125.A is a unique embedded ceramic miniature loop antenna designed for multi-band GNSS applications, covering GPS, GLONASS, Galileo, and BeiDou systems to achieve centimeter-level accuracy with RTK. This compact SMD component measures just 10 x 3.2 x 1.5mm and is tuned for mounting on an 80x40mm ground plane. It features high efficiency up to 93%, a peak gain of up to 4.13 dBi, and an omnidirectional radiation pattern, maintaining stable reception across all GNSS bands from 1164MHz to 1602MHz. Its small footprint and robust performance make it an ideal solution for compact devices such as high-precision automotive navigation, asset tracking, UAVs, and robotics.
