We spoke to Roger Thornton, principal hardware engineer, about the new antenna:

“The Raspberry Pi 3 antenna is a surface-mount component,” explains Roger, “whereas the Zero W antenna is a resonant cavity which is formed by etching away copper on each layer of the PCB structure.”

The technology is licensed from a Swedish company called Proant (you can see the credit on the reverse of the Zero W board).

“They’re very clever boffins,” says Roger. “It’s a really neat design.”

The triangle recession in the board is known as the ground plane. This free space is used to interact with the radio waves. They resonate in this cavity at just the right frequency. The two components at the small side, right up by the board, are a couple of capacitors which capture the radio signal.

Here’s a sweet, sweet diff image of the new Zero W and the previous Zero version.
