This looks like what some illiterates might name a baby. It's also hideous looking. And starting with 'ant' doesn't help it. The only times I've heard people pronounce it (in Ohio), they stress the first syllable, not the second.
When parents pick a name like this for their child, it makes me wonder if they specifically don't want the child to be successful. People will assume that either the person himself or the parents are bad spellers. This spelling makes the person and his parents alike look uneducated.
