Product overview
The VLG Built-in GPS BDS 25x25mm active ceramic Antenna 18dBi supports GPS and BDS for joint positioning and navigation across multiple systems. Its ceramic construction has a 25mm × 25mm footprint, with applications including trackers, cars, electric vehicles, navigation equipment and instruments. The antenna combines dual-band support with an interference-reduction design intended to reduce electromagnetic interference generated by nearby electronics and the surrounding environment. Its polarization is right-hand circular, designated RHCP.
The active assembly combines the antenna element, LNA and cable in a 25mm(L)×25mm(W)×4.5mm(H) format, with a customizable Φ1.13 coaxial cable and IPEX connector. It operates at DC 3.0±0.3V, draws 5mA maximum and provides typical LNA gain of 18±2dBi. Minimum bandwidth is 20MHz and output impedance is 50Ω. The passive antenna measures a typical 25mm(L)×25mm(W)×2.0mm(H), with typical peak gain of ≥1.0 dBi and efficiency of ≥40%.
