Construction Strategy of 5G Base Station Antenna in 2.6 GHz and 700 MHz Band

In view of the "two multiple and one fast" characteristics of China Mobile’s base station antenna feeder and the challenges of high rent and resource shortage, this paper proposes an overall idea for antenna feeder construction, which comprehensively considers the frequency bands of different standards and adopts multi-band and multi-port independent electric tuning antenna for antenna deployment integration. Then, the antenna deployment target is 2 antennas per physical cell and the integration principles of antenna feeder are "active and passive separation" and "TDD and FDD separation". Furthermore, with the overall consideration of 5 G bands of 2.6 GHz and 700 MHz and the combination of the following 5 G construction steps, 4 major kinds of scenarios are determined with the corresponding detailed construction solution for antenna feeder integration. Finally, the requirements of the antennas with 5 G antenna feeder integration are estimated and the suggestions for 5 G antenna feeder construction are given.
