4.Product Introduction
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).
LHCP Polarization for Signal Clarity
Left-Hand Circular Polarization (LHCP) minimizes signal interference and multipath distortion, ideal for GPS and satellite communication systems.
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.
Compact and Easy Integration
Compact dimensions (26.0±0.3mm length) and 50Ω impedance simplify PCB integration for IoT devices, drones, and telemetry systems.
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.
FAQ
Q:What is the operating temperature range?
A:The antenna functions reliably from -40°C to 105°C and survives storage up to 105°C.
Q:Does it require a ground plane?
A:Yes, optimal performance requires a 70mm ground plane (customer-provided).
Q:Is it compatible with standard PCB soldering?
A:Yes, terminals withstand 260–290°C soldering baths with ≥95% solder coverage.
Q:How to mount the antenna?
A:Use adhesive tape (included) on a flat surface; ensure no nearby metal obstructions.
Q:What devices use LHCP polarization?
A:Common in GPS receivers, satellite modems, and applications needing interference rejection.
Q:Can it survive outdoor humidity?
A:Yes, tested for 96–98h at 90–95% RH and 60°C.
Q:What’s the typical return loss?
A:VSWR ≤1.5 at center frequency ensures minimal signal reflection.
