Here a Radio-Antenna of small size

Internet is a major requirement for any electronic device which results in the concept of “Internet of Things”. Internet of Things is nothing but an interconnection between uniquely identifiable embedded computing devices. The basic requirement is just that the devices should come under the existing Internet infrastucture. But there is a problem with this concept. If a wireless radio is added to any device, the power consumption of the device increases. Now an electrical engineering team from Stanford has come up with a solution to this problem.





In collaboration with researchers from the University of California, the team has developed a wireless radio antenna which is just like an ant and it doesn't even require any battery. Even if a battery is put inside it, it's not very significant one. The wireless radio is quite cheap too and if it's installed to any gadget, it will not cost much either. The device is energy efficient and it gathers all the power from the same electromagnetic waves. This tiny wireless chip is designed to “compute, execute and relay commands”, as per a statement from Stanford. As it's quite cheap, this chip can become a missing link between the Internet and Internet of Things.

The antenna on the chip is one-tenth the size of a standard Wi-Fi antenna and also operates at 24 billion cycles per second. The wireless chip's other components are a receiving antenna, a transmitting antenna and a central processor. Hundreds of these prototype wireless chips have been designed by a semiconductor company in France and the engineering team has tested them. Amin Arbabian, an assistant professor of electrical engineering, demonstrated this ant-sized radio chip at the VLSI Technology and Circuits Symposium in Hawaii.
