Researchers have developed the world's smallest television antenna without having to compromise on reception or the conditions under which it can operate. The dual antenna created at the University of Morelos (UAEM) in Mexico receives analog TK and digital broadcast channels while measuring just 11 centimeters long, 6.5 cm wide, 6 mm thick and weighing only 12 grams (when coated, the weight reaches 80 grams).
The outdoor antenna is a compact rectangle that actually contains an array of small antennas. It is designed to be fixed to a roof without an attached mast, and operate under even very low temperatures. It can also be used indoors without any attachment and can be run through a signal splitter to connect to multiple TVs. It does not require electricity to operate.
"The idea came from applying new materials and new geometries, to create a smaller antenna in comparison to those that already are available," says Dr. Margarita Tecpoyotl Torres, leader of the project at UAEM.
She says that when the antenna was tested in California it was able to pick up 70 signals, and was also capable of picking up 28 digital signals in Mexico City.
The development of the antenna led to the creation of a spin-off company, INNTECVER, S.A. de C.V., which is looking for opportunities to commercialize and mass produce the new technology.
