摘 要: 为提高移动通信网络优化的工作效率,设计一种新型电子下倾角检测系统。该系统根据基站天线电子下倾角取决于天线振子相位差的关系,通过检测相位差,计算电子下倾角。系统基于中国移动4G基站的2.35 GHz载波频率,设计了3 dB耦合器、微波振荡器、单平衡混频器及微波低通滤波器,由ADS软件进行仿真试验。仿真结果表明,该系统具有较高的电子下倾角检测精度,可行性较好。且该系统可通过修改电路参数,应用于其他频段天线电子下倾角的检测,具有较强的适用性。

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 electronic declination angle and the phase difference of the antenna element, the system calculates the electronic declination angle by detecting the phase difference. Based on the 2.35 GHz carrier frequency of China Mobile 4G base station, the system designs 3 dB 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 electronic declination angle in other frequency bands and has strong applicability.
