片上天线实现高效太赫兹辐射 数据传输速率高出现有器件数百倍

Core Insights - A research team from Singapore, France, and the USA has developed a compact on-chip antenna based on topological photonics, which significantly enhances data transmission rates for future 6G wireless communication [1][2] - The anticipated 6G network aims to achieve a data rate of 1 terabit per second, enabling the transmission of approximately half the storage capacity of a mid-range smartphone in one second [1] - Current challenges in antenna technology for terahertz frequencies include efficiency, coverage, and reliability, which must be addressed for successful deployment of 6G networks [1] Group 1 - The team designed a silicon chip with an array of holes of two different triangular sizes (99 micrometers and 264 micrometers) to control terahertz radiation [2] - This design allows for the creation of a conical radiation beam, making the chip itself function as an antenna, achieving over 30 times the coverage range of existing terahertz antennas [2] - The antenna's data transmission rate is hundreds of times higher than current state-of-the-art terahertz devices, with all functionalities achieved through passive structures embedded in the chip's geometric design [2] Group 2 - The next step for the research team is to integrate the transmission, reception, and signal processing functions of terahertz communication systems into a single chip [2] - If successful, this integration could enable future 6G networks to efficiently handle terahertz signals, similar to existing low-frequency communications, laying the groundwork for ultra-high-speed wireless communication [2]
