Ohio State University researchers are finding ways to incorporate radio antennas directly into clothing, using plastic film and metallic thread.

They describe a new antenna design with a range four times larger than that of a conventional antenna worn on the body - one that is used by American soldiers today.

"Our primary goal is to improve communications reliability and the mobility of the soldiers," said Chi-Chih Chen, a research associate professor of electrical and computer engineering at Ohio State.

"But the same technology could work for police officers, fire fighters, astronauts - anybody who needs to keep their hands free for important work," he stated.

The Ohio State system takes elements from previous research and combines them in a new way, with the addition of a unique computer control device that lets multiple antennas work together in a single piece of clothing.

The result is a communications system that can send and receive signals in all directions, even through walls and inside a building, without a need for the wearer to carry an external antenna.

"In a way, we're doing what's already been done on a cell phone. You don't see cell phones with external antennas anymore, because the antenna is part of the body of the phone," said John Volakis, the Roy and Lois Chope Chair Professor and Director of the ElectroScience Laboratory at Ohio State.

Now, the engineers are working on printing the antennas directly onto clothing, and embroidering antennas into clothing with metallic threads.

The study was reported in the current issue of the journal IEEE Antennas and Wireless Propagation Letters.
