Signal Amplifiers, Antennas Mobile sewn in shirt

Antenna that serves as the phone signal amplifier can now be sewn on the shirt. This antenna is claimed to have a range four times greater. Thus the findings of the latest technology team of researchers from Ohio State University.

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 similar antennas mounted on the body. Its implementation could in some areas, but priority for the military field.

"Our main goal is to improve the resilience of communications and mobility of the soldier," 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 that it can perform other work."

The idea is to hide the antenna is not new. Mobile phone industry has left an external antenna and switch to a device that can be hidden inside the device. But although is most successful mobile phone manufacturer to do well, Apple is actually problematic in this regard.

When the iPhone 4 was launched, a number of shoppers 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 to weaken.

It does not matter to a team from Ohio State University, given the way the antenna prototype was first plastered with a layer of plastic, which is then stitched with thread using a regular sewing machine. To ensure the signal strength of the antenna radiating in all directions, the antenna accidentally installed more than one - in the front, back and sleeve part.

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.
