VSU researchers at the Department of Electronics of the Faculty of Physics create unique technologies that are popular all over the world. The research is conducted at the Russian-Chinese laboratory "Information technologies and fractal signal processing" (Head Researcher – Alexander Potapov, Dr. habil. in Physics and Mathematics). Scientists from the Jinan University (Guangzhou, China), the Institute of Radio-engineering and Electronics of RAS, and the Department of Electronics at VSU are working together on fractal chip antennas for various frequency ranges.
– Every device has a Wi-Fi module for Internet connection. Such modules have an antenna in them in the form of a small chip. The antennas operate in various frequency ranges: GSM, 3G, and 4G. The VSU Faculty of Physics has been collaborating with Alexander Potapov, the Head Research Fellow at the Institute of Radio-engineering and Electronics of RAS, for about 30 years. Following the request of our Chinese partners, Chuangtian Electronic CO LDT Corporation, we have designed and produced sample antennas on the basis of various fractal curves. The corporation, having all the necessary equipment, can start a serial production of such antennas. The samples were finished in September 2014. Now the Chinese partners have studied the results and invited our researchers on a business trip to China.
The antennas are based on the samples, designed in the USA, which were then improved: they are 5% smaller and have a better frequency response. The researchers have constructed two more fractal-based types of antenna. One of them is 1.5 times smaller than the sample antenna, while another works much better.
It is planned, that the results will be adapted to certain technologies used in China. The assortment will be broadened to suit various purposes (eg. RGID systems, access systems, and electronic key systems).
