Product Information
Full details
This MOLEX 47950-2011 WiFi antenna is designed for engineers and hobbyists needing reliable 2.4GHz and 5GHz wireless connectivity in compact devices. Its key benefit is providing omnidirectional radiation with a 4.4dBi gain for improved signal strength in a flexible, adhesive-backed form factor. A potential caveat is its specific cable length of 200mm, which may require careful placement planning.

FAQs
What is the impedance of this antenna?
The input impedance of this antenna is 50 ohms, which is standard for most WiFi applications.
What type of connector does the antenna cable have?
The product description does not specify the connector type. It is typically a U.FL or similar small coaxial connector. Verify compatibility with your device before purchase.
Can this antenna be used outdoors?
This antenna is designed for internal mounting. It is not rated for outdoor use and may be damaged by exposure to weather elements.
What is the operating frequency range?
The antenna operates on the 2.4GHz and 5GHz WiFi bands, with a specified frequency range from 4.8GHz to 5.9GHz.
How is the antenna powered?
This is a passive antenna; it does not require its own power source. It relies on the radio frequency signal from your WiFi module.
What is the maximum operating temperature?
The product specifications do not list a maximum operating temperature. For best results, avoid environments exceeding typical electronic device operating temperatures.
Troubleshooting
No WiFi signal or weak connection
Ensure the antenna cable is securely connected to the WiFi module. Verify the antenna is not obstructed by metal components and is placed in an optimal location. Check that the correct frequency bands (2.4GHz/5GHz) are enabled in your device's settings.
Antenna not adhering properly
Clean the mounting surface with isopropyl alcohol and allow it to dry completely before re-applying. Ensure the surface is smooth and free of dust or oils. If the adhesive is old, consider using a small amount of appropriate electronic adhesive.
Interference with other components
Reposition the antenna to maximize distance from other sensitive electronic components or power sources. Shielding nearby components may also help reduce interference.
Pros and Cons

- Supports both 2.4GHz and 5GHz WiFi bands for broad compatibility.
- Offers a 4.4dBi gain for enhanced signal performance.
- Flexible construction allows for easy integration into tight spaces.
- Adhesive mounting simplifies the installation process.
- Omnidirectional radiation pattern ensures consistent signal coverage.
Cons
- The 200mm cable length might be restrictive for some designs.
- Adhesive may degrade over time or in extreme environmental conditions.
- Requires a suitable surface for optimal adhesive performance.
- Performance can be affected by proximity to other electronic components.
Setup, Compatibility & Care
Setup:
- Identify a suitable internal location within your device that allows for the 200mm cable to reach your WiFi module's antenna connector (typically U.FL or similar).
- Clean the mounting surface thoroughly to ensure optimal adhesion.
- Peel off the protective backing from the adhesive.
- Carefully press the antenna onto the chosen surface, ensuring firm contact.
- Connect the antenna's cable to the appropriate port on your WiFi module.
Compatibility:
This antenna is designed to work with any WiFi module or device that uses a standard connector compatible with its cable end and supports 2.4GHz and 5GHz frequencies. Always verify the connector type on your module before purchase.
Care:
- Avoid bending the antenna cable sharply.
- Keep the antenna away from sources of extreme heat or moisture.
- Periodically check the adhesive bond, especially if the device is subject to vibration.
