Is WiFi antennae an extra?

[sargan]

I have just been building up a PC, based on Gigabyte X670E Aorus Master
This has WiFi 6e …. But when putting together I found no WiFi Antennae included with the Motherboard.
It has the nice shiny brass connectors on rear panel … but nothing to connect to it.
Is the Antennae a separate purchase ?

I had lifted motherboard tray out, didn’t lift the under tray .. was there.
