Is this a microwave antenna in the top left corner?


Check this image of the Skylake Intel CPU die:

What do you think the rectangular feature in the upper left corner is?
Actual length of the feature is about 3.54mm along the longer side...

To me it looks awful lot like some sort of microwave antenna for around 43 GHz...

What could it be?

Either that, or a protection against hacking of its internal fuses.
