Model: KC.IA.00474
The KC.IA.00474 is an adhesive-backed FPC antenna for installation inside electronic devices. It covers 2400–2500 MHz for Wi-Fi and Bluetooth and 5150–5850 MHz for 5 GHz Wi-Fi.
Dual-Band Wi-Fi and 2.4 GHz Bluetooth
Covers both Wi-Fi bands with one antenna element. Bluetooth uses the 2.4 GHz band.
Compact FPC Element
The flexible antenna element measures 22.3 × 12.8 mm with a nominal thickness of 0.25 mm.
Adhesive-Backed Mounting
The peel-off liner exposes the adhesive for mounting inside the device enclosure.
RF1.13 Cable with Gen 1-Style Connector
The 50 Ω RF1.13 coaxial lead terminates in an I-PEX Gen 1-style micro-coaxial plug.
The TOXU KC.IA.00474 is a dual-band embedded FPC antenna for Wi-Fi and Bluetooth hardware. It covers 2400–2500 MHz and 5150–5850 MHz and combines a flexible antenna element, an adhesive backing and a pre-terminated 50 Ω coaxial lead in one assembly.
The small antenna footprint lets designers place the antenna on an interior enclosure surface and route the coaxial lead back to the host board. The finished assembly dimension from the FPC edge to the connector is 75 ± 3 mm.
2.4 GHz and 5 GHz Wi-Fi Coverage
The antenna covers 2400–2500 MHz for 2.4 GHz Wi-Fi and Bluetooth and 5150–5850 MHz for 5 GHz Wi-Fi.
22.3 × 12.8 mm FPC Footprint
The flexible printed circuit element has a nominal thickness of 0.25 mm for integration inside compact housings.
Peel-and-Stick Installation
The adhesive backing secures the antenna to a suitable interior surface after the release liner is removed.
Pre-Terminated RF1.13 Coaxial Lead
The black RF1.13 cable has a nominal outer diameter of 1.13 mm and an I-PEX Gen 1-style micro-coaxial plug.

The assembly consists of a black FPC antenna element, an adhesive backing, an RF1.13 coaxial lead and a micro-coaxial plug. The FPC element measures 22.3 × 12.8 mm nominally, with a ±0.2 mm tolerance on each side.
For mechanical layout, use the 75 ± 3 mm finished dimension measured from the FPC edge to the connector. Allow room for cable routing and for access to the mating receptacle during assembly.

IoT Gateways and Controllers
For compact gateways and controllers that use an internal antenna for Wi-Fi connectivity or Bluetooth commissioning.
Smart Home and Building Devices
For sensors, control panels and other connected devices with space to mount an antenna inside the housing.
Handheld Electronics
For handheld designs that need to place the antenna away from the radio board while keeping it inside the enclosure.
Verify the mating receptacle part number and available cable reach before selecting the antenna. During prototype assembly, check that the cable can reach the receptacle without pulling on the plug or the FPC solder joint.
Evaluate antenna performance with the housing closed and with nearby metal, the battery and the main PCB in their production positions. Use the intended cable routing during testing, since the enclosure and nearby components can affect RF performance.
TOXU supplies antennas, RF coaxial cable assemblies and connectors for OEM integration. For a custom configuration, share your frequency bands, enclosure layout, connector part number and required cable reach so TOXU can review the design requirements.
Antenna and Interconnect Selection
Review the antenna footprint, cable route and mating interface together when selecting components for your device.
OEM Configuration Review
Provide your mechanical and RF requirements for a review of cable length, connector and antenna configuration options.
TOXU develops and manufactures communication antennas, GNSS antennas, RF cable assemblies and connectors. TOXU also provides PCBA manufacturing and RF hardware integration services for OEM customers.
Which frequency bands does this antenna cover?
It covers 2400–2500 MHz and 5150–5850 MHz. The lower band is used for 2.4 GHz Wi-Fi and Bluetooth. The upper band is used for 5 GHz Wi-Fi.
What does the 75 mm dimension measure?
The finished assembly is specified at 75 ± 3 mm from the FPC edge to the connector.
How do I check whether the plug fits my board?
The assembly uses an I-PEX Gen 1-style micro-coaxial plug. Check the receptacle part number or share its drawing with TOXU for review before ordering.
Can I request a different cable length or connector?
Share your target dimensions and the mating connector part number so TOXU can review the requested configuration.
