4.Product Introduction

1. High Frequency Stability
   Operates at 2338MHz ±10MHz with a low temperature coefficient (20ppm/°C max), ensuring reliable performance in extreme environments (-40°C to 105°C).

2. LHCP Polarization for Signal Clarity
   Left-Hand Circular Polarization (LHCP) minimizes signal interference and multipath distortion, ideal for GPS and satellite communication systems.

3. Robust Environmental Durability
   Passes rigorous tests including humidity (90–95% RH), thermal cycling (-40°C↔105°C), and vibration resistance (10–55Hz), ensuring longevity in harsh industrial or outdoor settings.

4. Compact and Easy Integration
   Compact dimensions (26.0±0.3mm length) and 50Ω impedance simplify PCB integration for IoT devices, drones, and telemetry systems.

5. High Zenith Gain
   Delivers ≥5.0dBi gain at 90° zenith, enhancing signal strength for applications requiring vertical coverage, such as vehicle tracking or remote sensors.

Application scenarios

• GPS Navigation Systems: Ensures stable signal reception in automotive or marine GPS units.

• Industrial IoT Sensors: Withstands factory-floor vibrations and temperature fluctuations.

• Drone Communication: Lightweight design and high gain support long-range UAV telemetry.

• Smart Agriculture: Resists humidity in outdoor farming sensors.

• Satellite Ground Stations: LHCP reduces interference in satellite data links.
