This subject belongs to a national major scientific and technological special project, called "A New Generation of Broadband Wireless Mobile Communication Networks". Active antenna technology enables the integrated design of RF components and antennas. Compared with passive antenna technology, it can flexibly change the horizontal and vertical beam pointing in actual network construction. Additionally, it can dynamically adjust the configuration of networks, optimize network structure, improve customer experience and the flexibility in network deployment, and reduce the investment for network building as the customers and services change.
