Overview
The TOXU TX-G003 is a 25×25×6 mm passive ceramic patch antenna engineered for embedded GPS/GNSS applications. With RHCP polarization, low VSWR, and 50 Ω matching, it provides stable reception across GPS L1 (1575.42 MHz), GLONASS L1 (1602 MHz), and BeiDou B1 (1621 MHz). Its SMD/embedded feed design simplifies integration into vehicle navigation systems, IoT trackers, and positioning modules.
The high-quality ceramic material and optimized patch geometry deliver ~5 dBi passive gain and >10 MHz bandwidth, supporting reliable signal lock even in compact devices. TOXU offers OEM/ODM services including tuning on your ground plane, layout guidance, and size customization to meet different mechanical envelopes and performance targets.
