Antenna DELOCK 2.4 GHz I-PEX MHF® I plug omnidirectional 2–3 dBi with 15 cm FPC cable for internal adhesive mounting

DELOCK 2.4 GHz WiFi antenna with I-PEX MHF® I plug is an internal omnidirectional antenna designed to improve wireless performance in devices operating on the 2.4 GHz band. The compact antenna delivers a gain of 2–3 dBi and is supplied with a 15 cm flexible printed circuit (FPC) cable with a 1.13 mm thickness, allowing connection to boards or radio modules using an I-PEX MHF® I socket. It is intended for adhesive mounting inside enclosures, enabling discreet installation without external protrusions.

Advantages

The antenna provides uniform omnidirectional coverage for short to medium-range 2.4 GHz communications and a modest gain of 2–3 dBi to assist in improving signal strength compared with built-in PCB traces. Its 15 cm FPC cable offers flexible routing inside small housings, while the I-PEX MHF® I plug ensures a standardized, low-profile connection to compatible radio modules. Adhesive mounting simplifies internal placement and reduces the need for mechanical fastening features in the enclosure.

How to use

Connect the I-PEX MHF® I plug to the corresponding socket on your wireless module or PCB, ensuring the connector is aligned and fully seated. Peel off the protective layer from the adhesive backing and place the antenna on a flat surface inside the device enclosure, positioning it away from large metal objects and high-noise components to reduce attenuation. Route the FPC cable carefully to avoid sharp bends and secure it within the enclosure if necessary. Reassemble the device and verify wireless performance with appropriate signal-testing tools.

Recommendations

For optimal performance, mount the antenna on a non-metallic surface and maintain some separation from metal shielding and batteries. Test different internal positions to find the best orientation for signal coverage. When replacing or connecting the antenna, handle the I-PEX plug and FPC cable gently to avoid damaging the fine connector or cable traces.
