Product Advantages
Compact Ceramic Patch Design
The 25 × 25 × 4 mm ceramic antenna element is suitable for space-constrained electronic designs. Its compact structure gives equipment manufacturers flexibility when planning antenna placement inside positioning devices and embedded systems.
Integrated LNA for GPS Signal Reception
The built-in low-noise amplifier provides 28 ± 2 dB gain with a noise figure below 1.5 dB. Combined with RHCP polarization, this configuration is designed for GPS L1 signal reception in compatible receiver systems. The antenna gain and LNA gain are specified separately to clarify the actual performance parameters.
Flexible Cable and Connector Options
The antenna supports RF1.13 cable and IPEX connector configurations, with alternative options available for discussion. The 2.2–5 V DC operating range and compact dimensions allow engineers to evaluate the product against different equipment interfaces and installation requirements.
Core Applications
- GPS navigation and positioning equipment
- Vehicle tracking and telematics devices
- Embedded GPS receiver systems
- Portable positioning terminals
- GPS-enabled industrial electronics
Application suitability depends on the receiving module, antenna placement, power supply and overall system design.
