Overview

The TOXU KC.IA.00526 is a 50 Ω internal PCB antenna designed for the 2.4 GHz and 5 GHz Wi-Fi bands. Its single-sided FR4 element is supplied with a gray RF1.13 coaxial lead and a first-generation I-PEX-type plug.

The coaxial lead allows the antenna to sit away from the host PCB, giving equipment designers flexibility when positioning the antenna and routing the cable inside the enclosure.

Key Features

2.4 GHz and 5 GHz Wi-Fi Coverage

The antenna covers 2400–2500 MHz and 5150–5850 MHz for dual-band Wi-Fi equipment.

Narrow FR4 Antenna Element

The 32.0 × 8.8 mm PCB footprint helps engineers evaluate antenna placement in space-constrained enclosures.

Pre-Attached Micro Coaxial Lead

The 80 mm nominal RF1.13 lead connects the antenna to a matching RF receptacle on the host PCB.

Technical Specifications

Hardware Structure

The antenna element is a 0.8 mm nominal FR4 PCB with a soldered coaxial feed. The finished drawing specifies a PCB length of 32.0 mm (+0.4/−0.2 mm) and a width of 8.8 ± 0.3 mm.

Applications

IP Phones and Communication Terminals

For equipment designs that require an internal antenna for both 2.4 GHz and 5 GHz Wi-Fi.

Embedded IoT and Control Equipment

For compact devices where the antenna needs to sit away from the host board’s RF receptacle.

System Integration

PCB antenna → RF1.13 coaxial lead → Host PCB RF receptacle

Verify the mating receptacle and cable reach before finalizing the layout. Evaluate antenna performance with the enclosure closed and the cable routed as it will be in production.
