2G/4G合路天线整治谐波干扰应用研究

Study on the Application of 2G/4G Composite Antenna to Control Harmonic Interference

为了降低和消除因空间隔离度不足引起的2G(900M)谐波干扰影响4G小区(F频段)的情况,提高网络通信质量,利用2G/4G合路天线替换原有的2G和4G独立天线的方式,通过合路天线的内置隔离度,实现2G信号与4G信号的互不干扰。分别更换不同厂家的2G/4G合路天线,通过在相同条件下进行对比测试得知,谐波干扰得以明显改善或彻底消除。通过2G/4G合路天线整治谐波干扰应用的研究,验证了合路天线改善谐波干扰的可行性和有效性。

In order to reduce and eliminate the impact of 2G（900M） harmonic interference caused by the lack of spatial isolation, which affected the 4G cell（F band）, and improve the quality of network communication, 2G/4G composite antenna was used to replace 2G/4G independent antenna to realize the coexistence of 2G and 4G signals without interference by means of the built-in isolation of the antenna. With 2G/4G composite antennas of different manufactures, the comparative tests under the same conditions demonstrate that harmonic interference can be completely eliminated or significantly improved. The research on 2G/4G composite antenna to control harmonic interference successfully verified the feasibility and the effectiveness of the composite antenna to improve harmonic interference.
