Antenna DELOCK 2.4 GHz omnidirectional 3.4 dBi I-PEX MHF® I plug with 18 cm FPC cable for internal adhesive mounting

DELOCK internal Wi‑Fi antenna for 2.4 GHz networks provides omnidirectional radiation with 3.4 dBi gain. The antenna is fitted with an I-PEX MHF® I male plug and an 18 cm FPC (1.13) cable for concealed adhesive mounting inside devices. It is designed to improve wireless reception and transmission in compact devices where an internal solution is required, such as routers, IoT modules, laptops and industrial electronics.

Advantages

This antenna offers omnidirectional coverage at 2.4 GHz with a moderate gain of 3.4 dBi, enabling better signal stability in confined or enclosed device housings. The I-PEX MHF® I male connector and the flexible 18 cm FPC cable allow easy connection to compatible RF modules without external cabling. The flat form factor and adhesive-ready backing make it suitable for internal mounting in small enclosures while minimising space usage and preserving device aesthetics.

Suitable for

• Internal Wi‑Fi enhancement in routers and access points
• Embedded wireless modules and IoT devices
• Laptops, tablets and compact consumer electronics
• Industrial control units and instrumentation with internal antenna requirements

Key specifications

• Frequency band: 2.4 GHz
• Radiation pattern: omnidirectional
• Gain: 3.4 dBi
• Connector: I-PEX MHF® I male plug
• Cable: 18 cm flexible FPC (1.13) cable
• Mounting: internal adhesive mounting (flat form factor)

How to use

Prepare the device interior by identifying a flat area on the inside of the enclosure free from metal obstructions. Connect the I-PEX MHF® I plug to the corresponding RF jack on the wireless module or board, taking care not to bend the connector pin. Position the antenna with the adhesive backing onto the selected surface and press firmly to ensure adhesion. Route the FPC cable so it does not obstruct moving parts and avoid sharp folds that can stress the cable. Reassemble the device and verify wireless performance with standard network diagnostics.

Recommendations

Place the antenna away from large metal masses and high-power heat sources to reduce detuning and signal absorption. If performance does not meet expectations, try alternative internal positions or rotate the antenna orientation; small adjustments can significantly affect reception and transmission in enclosed spaces.
