Rear heated window Bmw 440i convertible

[Shabbabrown]

Hi

I’ve noticed the top 3 lines of my rear window do not heat up and wondered if this was the antenna or perhaps damage wiring within the glass - which doesn’t make sense as I’ve inspected and looks fine. Can anyone suggest a solution or is it meant to be like this?

Cheers

On my E32 the upper 3 are the radio antenna.
