They have tried to do the best they can as regards spacing with the rather small internal antennas, which appear to be horizontally mounted dipoles for 5GHz and short loaded dipoles for 2.4GHz. There are onboard connectors for 5GHz but the 2.4GHz antennas are soldered to the PCB in these photos. J18 and J19 are probably intended for OEM test connectors.
