Introduction

SPATL1254BL5254_YXYW58 is a compact dual-band passive GNSS ceramic patch antenna designed for L1 and L5 signal reception. With a stacked dual-layer structure, RHCP polarization, low reflection loss and high gain performance, it provides reliable GNSS signal reception for receivers, modules and compact positioning terminal devices.

Key Features

Dual-Band GNSS Signal Reception

SPATL1254BL5254_YXYW58 supports L1 at 1575.42 MHz and L5 at 1176.45 MHz, enabling dual-frequency GNSS signal reception for positioning and navigation applications
Compact Stacked Patch Design

The antenna adopts a double-fed, double-layer stacked ceramic patch structure with 25 × 25 × 4 mm top and bottom layers, providing compact integration for space-constrained GNSS devices
Reliable Passive Antenna Performance

With RHCP polarization, 50 Ω impedance, VSWR ≤2.0 and typical zenith gain ≥0.5 dB, the antenna supports stable GNSS signal reception without requiring external power
Easy Integration and Durable Construction

Built with dielectric ceramic substrate, silver-plated electrode and ground base, copper tin-plated pins and 3M 468 adhesive, the antenna is suitable for reliable PCB-level integration into GNSS modules and terminal devices
