A Multi-Frequency Fusion Antenna Suitable for Power Tower Deformation Monitoring

The significant importance of power transmission line detection lies in monitoring the deformation of power transmission towers. A multi-frequency fusion antenna for power transmission tower deformation monitoring is proposed. This antenna integrates the GNSS section and the data transmission section. The GNSS section supports multiple satellite navigation systems, including BDS, GPS, GLONASS, and GALILEO frequency bands. By utilizing multi-system signal fusion, it overcomes the limitations of a single system under complex environments such as signal blockage and interference, achieving high-precision positioning. The data transmission section supports multiple frequency bands, including 2G/3G/4G LTE/5G NR, meeting the data upload requirements in the remote installation environments of power transmission towers. Experimental results show that the antenna exhibits excellent isolation between frequency bands, outstanding reflection coefficient, and gain performance. The radiation pattern remains stable across different frequency points, ensuring the accurate and efficient transmission of satellite navigation signals and monitoring data. This antenna has great application potential in the field of power transmission tower deformation monitoring.
