Hi, Stewart ang Group.

A very brief look at Balanis "Antenna Theory" has the passing comment

proximity effect can lead to greater loss than skin effect (on a

2196-2203.
The proximity effect increase losses indeed. The effect may be
substationaly greater than skin effect only. I have investigate by
myself this effect in solenoid few years ago both theoretically
and experimentally. Unfortunely I do not study this in loop. But it seems
that effect is large in loop as in solenoid.
