Design and Simulation of Electronic Downtilt Detection System for Mobile Station Antenna
Abstract:In order to improve the work efficiency of mobile communication network optimization, a new type of electronic declination angle detection system is designed. According to the relationship between the antenna declination angle and the phase difference of the antenna, the system calculates the electronic declination angle by detecting the phase difference. Based on the 2.35GHz carrier frequency of China Mobile 4G base station, the system designs 3dB coupler, microwave oscillator, single balanced mixer and microwave low-pass filter. The simulation test is carried out by ADS software. The simulation results show that the system has a high detection accuracy of electronic declination angle, and the feasibility is good. By modifying the circuit parameters, the system can be applied to the detection of the antenna declination angle in other frequency bands and has strong applicability.
