This high-performance Active Ceramic GPS Antenna is designed to provide superior signal reception for GPS modules like the NEO-6M, NEO-8M, or SIM5320E. Unlike passive antennas, this "active" model features an integrated Low Noise Amplifier (LNA) that boosts the satellite signal strength (up to 28dBi), ensuring a faster Time-To-First-Fix (TTFF) and better stability in urban environments.

Specifications

• Frequency: 1575.42 MHz (GPS L1 Band)
• Integrated LNA Gain: 28 dBi (Typical)
• Ceramic Patch Gain: 3 dBi
• Operating Voltage: 3V to 5V DC (Powered via the signal cable from the GPS module)
• Current Consumption: 10mA (Typical)
• Polarization: R.H.C.P. (Right Hand Circular Polarization)
• VSWR: 2.0 or less
• Impedance: 50 Ohm
• Connector Type: U.FL (IPEX / MHF1)
• Cable Type: 1.13mm Coaxial Cable
• Cable Length: 10 cm
• Dimensions (Ceramic Patch): Typically 25mm x 25mm x 4mm

Features

• High Sensitivity: The 28dBi total gain allows the antenna to pick up weak signals from GPS satellites even in challenging "urban canyon" environments or under light tree cover.
• Active Amplification: Includes a built-in LNA and SAW filter to amplify the desired GPS signal while filtering out out-of-band electronic noise.
• Plug-and-Play (U.FL): Equipped with a tiny U.FL connector, it snaps directly onto the antenna port of most modern SMD GPS modules and cellular boards.
• Adhesive Backing: Most versions include a 3M adhesive sticker on the bottom for easy mounting inside plastic enclosures or on dashboards.
• Compact Ceramic Build: The square ceramic patch is optimized for the circular polarization of GPS satellite signals, providing significantly better performance than standard wire antennas.

Common Applications

• Vehicle Tracking: Hidden GPS tracking units for cars, bikes, or fleet management systems.
• Drones and UAVs: Lightweight, high-gain positioning for flight controllers like Pixhawk or APM.
• IoT Handhelds: Portable mapping devices, outdoor data loggers, and wearable tech.
• Cellular Modules: Providing GPS functionality to 3G/4G modules (like the SIM5320E) that require an external active antenna for a signal lock.

Usage Tips

• Sky View: For optimal performance, the ceramic (light-colored) side of the antenna must face upward toward the open sky.
• Signal Obstruction: Avoid placing the antenna directly under metal sheets or thick carbon fiber, as these materials block GPS signals. Plastic, glass, and wood are generally transparent to the signal.
• U.FL Handling: U.FL connectors are fragile and rated for a limited number of mating cycles. Use a small tool or fingernail to snap it straight down onto the board; avoid applying sideways pressure or frequent disconnecting.
