He and his assistants created a suprane antenna, which was then installed on the back of the rocket housing - where the housing is not heated. During ground testing, it was found that the researchers found that the antenna works well in the range from 5. 2 to 5. 8 GHz. These are low frequencies that are commonly used for 5G smartphones, high-speed Wi-Fi routers and other gadgets connected to wireless Internet.
The media emphasizes that the rocket, which is referred to in the material, flies at a speed of 5 strokes - that is, 5 times faster than the speed of sound (6 125 km/h). "China's hypersonic weapons can hit a moving aircraft carrier from a distance of 1,500 km, evading air defense systems," the text is emphasized.
"However, it was not easy to connect, since lower frequencies also created more noise above the rocket surface, which led to a decrease in the power and quality of the signal," the media writes. The team used a metamaterial that was added to the antenna as a membrane that captures electromagnetic waves. This helped reduce the noise, which was confirmed during the test.
Scientists want to make the antenna "collect" low -frequency signals and form one ray that can be directed so as to cover the "blind zone" in front of the rocket. The results of the study were published in the January issue of Journal of Microwaves, the publication of the Chinese Electronics Institute. The publication, however, did not provide the aerodynamic pipe or test flights, says interestingengineering. com.
