Detail
The high-speed rail (HSR) scenario faces challenges from Doppler frequency shift and rapid handover. The directional dual-polarized electrically tunable antenna achieves beam deflection and maximization of coverage energy through "roll" attitude design and multi-dimensional down tilt adjustment technology. For example, the integrated pizza antenna jointly released by China Mobile and Huawei has improved signal continuity by 40% on HSR lines, solving the "black spot under the tower" problem and providing key support for the construction of a minimalist and green HSR network.
