TW3967 Embedded Triple-Band GNSS Antenna

Calian's TW3967 is an Accutenna® technology antenna providing triple-band GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, and Galileo E1/E5 plus L-band correction services coverage and is specially designed for precision triple frequency positioning. The TW3967 provides superior multi-path signal rejection, a linear phase response, and tight Phase Centre Variation (PCV). This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters. The TW3967 features a precision-tuned, twin circular dual feed, stacked patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering in each band and further amplified prior to recombination at the output. The antenna also has a strong pre-filter to mitigate intermodulated signal interference from LTE and other cellular bands. The TW3967 offers excellent axial ratio and a tightly grouped phase center variation. The TW3967 covers from 1164 MHz to 1254 MHz and 1525 MHz to 1606 MHz. The TW3967 is also available with 35 dB or 18 dB gain with a part number of TW3972E and TW3967LC, respectively. A 100 mm ground plane is recommended.
