Glenn Fleishman on antenna design

Glenn Fleshman, commenting on the Flickr set I just deleted because it was a pain to maintain:

The FCC doesn’t require antenna placement. Rather, it requires manufacturers to meet SAR rules: “Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a “safe” phone, as measured by these standards.”

Manufacturers typically design phones to keep the sweet spot as far away from the head as possible to make it easier to be below SAR limits while using the maximum possible power under spectrum licensing rules.
