When designing and producing Raspberry Pi devices, we consider as many potential use cases as possible — particularly when it comes to criteria like wireless (WLAN and Bluetooth) performance and antenna usage. While our single-board computers (such as Raspberry Pi 5) include only an on-board PCB antenna, our Raspberry Pi Compute Module range offers two pre-approved options: an on-board PCB antenna and the external whip antenna from the official Raspberry Pi Antenna Kit.



However, we recognise that some industrial and commercial customers may need to employ third-party antennas for their applications. Example scenarios include:

• Embedding a Compute Module within a metal enclosure, where the PCB antenna would perform poorly due to the Faraday cage effect
• Extending the communication distance of a device, which requires increased antenna gain
• Integrating an antenna with a different form factor, such as a flexible PCB antenna

In such cases, the Compute Module and new antenna may be required to undergo additional testing and certification before the product can be sold. While procedures vary depending on the market and the device’s features, Raspberry Pi is well placed to support our customers in meeting these additional requirements — either by updating our existing certifications or by obtaining new certifications on their behalf.
