Antenna prototype of the new model is made from layers of plastic and metal thread. The results reported in the journal IEEE is claimed to have a range four times greater than a similar antenna mounted on the body. Its implementation could in some areas, but priority for the military field.
"Our ultimate goal is to increase the resilience of communications and mobility of soldiers," said Chi-Chih Chen, one of the researchers. "But this technology can also be used for police officers, firefighters, astronauts, or anyone who does not want to hand hold the antenna so it can still do something else."
The idea is to hide the antenna is not new. Mobile telephone industry has left an external antenna and switch with a device that can be hidden inside the device. But although is most successful mobile phone manufacturers to do well, Apple is actually problematic in this regard.
4 When the iPhone launched, a number of buyers reported a problem receiving antenna. They found that when holding the phone, their skin is exposed to a short circuit in the region near the antenna, causing the signal weakens.
It does not matter to a team from Ohio State University, given the way the antenna prototype is first attached by a plastic layer, which is then stitched with thread using a regular sewing machine. To ensure the signal strength of the antenna radiating in various directions, the antenna accidentally installed more than one - in front, rear and the sleeves.
To implement this technology, it takes at least 200 U.S. dollars per person. The cost is likely to decline if it is mass produced.
