On The Key Technologies For The Controller Of Electrical Adjustable Antennas

In this paper, the core issues emerged in the design of the controller for electrically adjustable antennas are mostly inverstigated. With detecting and controlling the movement of the phase shifter, the controller for electrically adjustable antennas can realize the function of adjusting the under inclination freely, so as to solve the signal interference issues and so on. This paper focuses on analysising and resolving the two following aspects: (1)To calibrate the cumulative error emerged in the course of measuring the phase-shifting angle of phase shifter (2)To carry out self-calibration of the benchmark loss arising from brown-out in the work process.This paper firstly introduce the application background of the electrically adjustable antennas as well as a variety design of the controller for electrically adjustable antennas, then improve the original ideas design, and further proposed a new design of the controller for electrically adjustable antennas. The purpose is to use the controller to control the under inclination of the electrically adjustable antennas, and improve the control performance of the under inclination of electrically adjustable antennas. In the new design of the controller for electrically adjustable antennas, mainly joined the photoelectric sensor, through the analysis of the photoelectric signal generated by the process of photoelectric sensor and shading slider movement, so as to solve the two main issues emerged in the previous design of controllers for electrically adjustable antennas.
