An Approach for Optimal Two-Dimensional Independent Antenna Electrical Adjustment

Co-site and co-antenna for multimode networks are effective ways to resolve the problem of space limitation for antennas installation during project implementation, while it brings inconvenience in coordinate optimization for multimode networks. After deep analysis on the electrical adjustment principle of antennas, this paper provides a solution synthesizing both the physical feeding network and multi-array signals. In this way, the horizontal azimuth and down tilt of antennas for different radio access technologies (RATs) can be independently adjusted, resolving the problem of coordinate optimization for multi-band antennas in co-antenna and co-sites scenarios.
