Ah those crafty Buckeyes. Researchers at Ohio State have been conducting some scientific tomfoolery in the world of embeddable antennae. You knew I was going to say that, didn’t you?
The researchers are trying to input an omnidirectional antenna in your shirt  antenna to boost radio reception. It works by using a computer controller the size of a deck of cards clipped to the wearers belt, The system senses body movement and activates the appropriate antenna to get the best signal. Of course, this depends on the user actually wanting  a better signal. I prefer my signals paltry at best.
This is, again, just a concept design. It’s not like you can go into the Gap and get antenna-enhanced clothing. Sigh. One day.
