First, antennas are diversifying. The third generation of mobile communication has more standards, and different standards have different requirements for antennas. In particular, the antenna requirements of the TD system are very different from the previous two generations, and it is a revolutionary form of mobile communication antenna.

Second, 3g antennas are developing towards integration. Because there are multiple standards for mobile communication, there are often multiple operators in one area, which results in antennas, environmental impact, and serious waste. Some countries have also begun legislation requiring common towers and even common antennas to avoid this situation. This requires that we must integrate multi-standard antennas to meet the requirements of regulations.

Third, the antenna is developing towards electrical modulation. With the development of communication and the increase of capacity, higher requirements are placed on the convenience of network optimization. In addition to the integration requirements, the antenna's downtilt must be adjusted "electrically" rather than mechanically.

Fourth, the antenna is developing towards beautification. With the improvement of the economic level and living standards, people have higher and higher requirements for the living environment, and the antennas in the forest affect the aesthetics of the environment. The appearance and installation of the antenna must be designed to fit the environment.

With the advancement of technology and craftsmanship, I believe that 3g smart antennas will develop along high-tech and high-end technologies.
