Product Description

Product Description

GLS2559 Ceramic Antenna
This product series comprises compact ceramic patch antennas designed for GPS L1 band operation at 1575.42 MHz. All models feature Right-Hand Circular Polarization (RHCP) and a standard 50Ω impedance. They offer configurable bandwidth and gain levels across different models to suit varied performance requirements, while maintaining a consistent axial ratio for reliable signal reception. With small form factors and low-profile designs, these antennas are optimized for integration onto specified ground plane sizes. Ideal for space-constrained applications in consumer electronics, portable navigation devices, asset tracking, and IoT solutions requiring efficient GPS positioning.
