GPS Passive Sticker Antenna (V1.0)

The GPS Passive Sticker Antenna (V1.0) is a compact, lightweight passive Global Positioning System (GPS) antenna designed to receive satellite signals for GPS receivers and navigation modules. Unlike an active GPS antenna, a passive antenna does not contain a built-in Low Noise Amplifier (LNA) and therefore does not require an external power supply. It is commonly used with GPS receiver modules that already include an onboard LNA, such as u-blox NEO-6M, NEO-7M, NEO-8M, SIM808, SIM868, and other GPS-enabled modules.

The antenna is manufactured using a ceramic patch antenna element, conductive antenna traces, coaxial cable, RF connector (commonly IPEX/U.FL), and a self-adhesive backing that allows easy installation on flat surfaces such as enclosures, vehicles, drones, and electronic equipment.

The working principle of the GPS Passive Sticker Antenna is based on receiving L1 GPS satellite signals at 1575.42 MHz. The ceramic patch antenna captures weak radio frequency (RF) signals transmitted by GPS satellites and transfers them through the coaxial cable to the GPS receiver module. Since the antenna is passive, it relies on the receiver's internal amplification circuitry to process the received signals and calculate accurate position, speed, altitude, and time information.

Typical specifications include:

• Product Type: GPS Passive Sticker Antenna

• GPS Tracking Systems

The applications of the GPS Passive Sticker Antenna (V1.0) include GPS navigation systems, vehicle tracking devices, drones, UAVs, robotics, IoT devices, fleet management systems, asset tracking, portable GPS equipment, smart agriculture, surveying equipment, environmental monitoring, embedded systems, educational electronics, engineering projects, prototype development, and DIY electronics.

The advantages of the antenna include compact size, lightweight construction, no external power requirement, easy installation with adhesive backing, reliable GPS signal reception, low cost, flexible mounting options, durable construction, compatibility with various GPS modules, and long service life.

Safety Precautions

• Connect the antenna only to compatible GPS receiver modules.

• Handle the RF connector carefully to avoid damage.

• Install the antenna with the ceramic patch facing upward toward the sky for the best signal reception.

• Avoid placing the antenna near large metal objects or sources of electromagnetic interference.

• Do not sharply bend or pull the coaxial cable.

• Keep the antenna dry unless it is specifically designed for outdoor waterproof use.

Note: A passive GPS antenna does not contain a built-in amplifier (LNA). It should be used with GPS modules that provide their own RF amplification. If the GPS receiver does not include an internal LNA or requires a powered antenna, an active GPS antenna should be used instead.

In conclusion, the GPS Passive Sticker Antenna (V1.0) is a compact and reliable GPS signal reception antenna designed for use with GPS receiver modules that have built-in amplification. Its lightweight design, adhesive mounting, stable GPS signal reception, and compatibility with popular GPS modules make it an excellent choice for navigation systems, vehicle tracking, drones, IoT devices, robotics, embedded systems, educational electronics, and DIY engineering projects.
