The National Institute of Information and Communications Technology, Sharp Corporation, Mitsubishi Chemical Corporation, and TECHLAB Co., Ltd. have efficiently decreased the burden of a planar antenna for Non-Terrestrial Network functions by 47%, from 5.5 kg to 2.9 kg. This achievement was made attainable by way of the event of a brand new warmth dissipation machine design.
The collaboration built-in a carbon fiber-reinforced polymer (CFRP) warmth dissipation machine, using a composite materials that mixes carbon fiber prepreg and graphite sheet, into the NTN planar antenna. The required electrical efficiency of the antenna was confirmed, and it was examined as a satellite tv for pc communication consumer terminal. This development is predicted to broaden the vary of mobility platforms for deployment, together with drones and autos, enhancing communication hyperlinks in difficult environments.
In NTN, satellite tv for pc communications supply high-speed connectivity in areas the place terrestrial cellular networks are insufficient, similar to mountainous areas and disaster-affected areas. However, NTN planar antennas require satellite tv for pc monitoring performance, which generates important warmth. Thus, efficient warmth dissipation and miniaturization are essential for mounting these terminals on numerous mobility platforms.
The 4 corporations have been conducting analysis and improvement on supplies with excessive thermal conductivity and low weight, together with the design and analysis of warmth dissipation units. NICT recognized design tips and carried out analysis on the composite materials and machine construction. Mitsubishi Chemical developed the supplies used, whereas TECHLAB established the design and molding expertise for the warmth dissipation machine. Sharp built-in the CFRP machine into the antenna, reaching the numerous weight discount.
Evaluation of the antenna confirmed that the radiation sample variations had been inside acceptable ranges, and there was no distinction in obtain achieve traits. The lighter satellite tv for pc communication consumer terminal can now be mounted on a wide range of mobility platforms, together with industrial drones, broadening its software scope.
Looking ahead, the companions plan to conduct additional evaluations of warmth dissipation efficiency and mountability, whereas exploring optimum designs for numerous terminal configurations. They purpose to contribute to the sensible implementation of ultra-compact and light-weight satellite tv for pc communication consumer terminals for mobility functions.
