In the booming market for smart devices, personal trackers, and telematics solutions, reliable positioning is non-negotiable. The 1575.42MHz frequency is the bedrock of the civilian GPS L1 signal, the most widely used positioning frequency globally, and is also shared by new interoperable signals like Galileo E1 and BeiDou B1C.
Our 1575.42MHz Internal FPC Patch Antenna is the compact, high-performance solution you need to ensure accurate, rapid satellite lock in your next product design. Combining the superior signal reception of a patch antenna with the flexibility and low-profile footprint of FPC (Flexible Printed Circuit) technology, this antenna is specifically engineered for devices where space is at an absolute premium. It transforms the challenge of embedding GPS into a seamless integration process, providing the precision of global navigation while remaining entirely invisible to the user.
Technical Excellence for L1 GNSS
This antenna is meticulously designed to receive the crucial L1-band signals from Global Navigation Satellite Systems (GNSS), including GPS, GLONASS, Galileo, and BeiDou.
High-Performance Signal Reception
The design combines the advantages of patch and FPC structures to deliver consistent, high-gain reception for crucial positioning data.
Tuned Frequency: Precisely tuned to 1575.42 MHz, the center frequency for the GPS L1 signal. This guarantees compatibility with the most common GNSS receivers worldwide.
Antenna Type: Patch/FPC Hybrid. It leverages the directional nature of a patch antenna for increased gain toward the sky, but is built on a flexible substrate for easy placement.
Polarization: Supports Right-Hand Circular Polarization (RHCP), which is essential for receiving satellite signals correctly and rejecting terrestrial multipath interference.
Impedance: Standard 50 Ohms, optimized for direct connection to any GPS/GNSS module on the market, ensuring minimal power reflection (low VSWR).
Gain and Efficiency: Engineered for high efficiency within a compact size, ensuring your device acquires and tracks satellites faster and maintains a reliable lock even in challenging urban environments.
Flexible and Compact Integration
Built on a flexible substrate and equipped with a micro-coaxial connection, this antenna is designed for complex, space-constrained assemblies.
Form Factor: Flexible Printed Circuit (FPC). This ultra-thin (often <0.2mm) material allows the antenna to be gently curved or adhered to the interior of a non-metallic enclosure's lid or side wall.
Cable and Connector: Utilizes a 1.37mm Micro-Coaxial Cable (often referred to as RG1.37), which is extremely thin, lightweight, and flexible, simplifying cable routing and minimizing interference in cramped spaces.
Termination: Typically terminated with a U.FL/IPEX/MHF type micro-connector, providing a secure, low-profile connection to the host PCB.
Mounting: Features a robust Peel-and-Stick (3M) Adhesive Backing for fast, reliable, and permanent installation onto plastic or glass surfaces.
Essential Use Cases and Applications
The 1575.42MHz Internal FPC Patch Antenna is the go-to component for products demanding precise location tracking and navigation within a concealed, ruggedized housing.
1. Wearable Technology and Personal Safety
Smartwatches and Fitness Trackers: Enables highly accurate distance and route tracking without a large, uncomfortable antenna. The FPC can be invisibly integrated into the watch casing.
Personal Locator Beacons (PLBs) & Medical Alarms: Ensures fast, reliable location fixes for emergency services. The small form factor is critical for devices worn by the elderly or outdoor adventurers.
Pet and Wildlife Trackers: The durability and internal mounting are ideal for tracking devices that are subject to constant movement and environmental exposure.
2. Vehicle Telematics and Asset Tracking
Fleet Management and OBD-II Trackers: Installed discreetly within the dashboard or under the trim of a vehicle. It provides the essential location data for route optimization, security, and driver monitoring.
Container and Cargo Tracking: The ability to be mounted internally allows the tracking device to be fully sealed and ruggedized (IP67+), protecting it from extreme temperatures and moisture during intermodal shipping.
Drones and UAVs: Essential for flight path accuracy and 'return-to-home' functions. The lightweight FPC design minimizes payload weight, maximizing flight time.
3. Compact Commercial Devices
Handheld GIS and Survey Equipment: Provides the necessary precision for field workers mapping infrastructure or collecting geographic data.
Portable Point-of-Sale (PoS) Terminals: Enables location-based services, security, and logistical tracking for mobile business devices.
Design Advantages for Engineers
Integrating this antenna offers tangible benefits over traditional ceramic or external GPS antennas, simplifying your design process and improving end-product reliability.
Maximized Integration Flexibility
The thin, flexible nature of the FPC allows you to use space that would be impossible for rigid ceramic patches. This design freedom is invaluable for creating thinner, sleeker, and more ergonomically friendly products. The generous cable length ensures you can distance the antenna from potential noise sources like the processor or display, significantly improving overall GNSS sensitivity.
Robust and Environmentally Protected
By embedding the antenna inside the enclosure, you protect the most vulnerable component of the GPS system from water ingress, dust, vibration, and accidental impact. This leads to fewer warranty returns and a more reliable product life cycle, especially in outdoor or industrial applications.
Consistent Performance
The patch element ensures a degree of directionality, favoring signals from the sky, which naturally mitigates the effect of ground-based signal reflections (multipath)—a common problem in urban canyons that plagues many linearly polarized or omnidirectional chip antennas.
Choose the 1575.42MHz Internal FPC Patch Antenna to power your next generation of location-aware, compact, and highly reliable connected products.
