中国首创！这一基础性国家标准获批立项

Group 1 - The core viewpoint of the news is the approval of the national standard for "Ultra-Wideband Horn Measurement Antenna," which is a foundational standard in the field of precision measurement of radio frequency and microwave parameters in China [1][2] - The standard is based on the key technology developed by Professor Shi Xinrong's team at the Guangdong Provincial Metrology Institute, which has previously won the second prize of the Guangdong Provincial Science and Technology Progress Award in 2023 [1] - The implementation of this standard is expected to save over 100 million yuan in operational costs annually, contributing to the high-quality development of China's 5G/B5G technology industry [1] Group 2 - The ultra-wideband horn measurement antenna is an important standard instrument in the field of precision measurement of radio frequency and microwave parameters, characterized by a wide frequency band, high efficiency, and strong beam directionality [2] - The establishment of this standard aims to address traditional design defects such as impedance mismatch and higher-order mode resonance, which have long been monopolized by Western countries, hindering the development of related industries in China [2] - The standard will scientifically quantify and specify key technical indicators such as frequency band, gain, flatness, standing wave ratio, and radiation pattern, effectively solving the long-standing technical challenges of "unable to measure or measure inaccurately" in radio frequency parameters [2]
