Description

Technical Field

[0001] This invention relates to the field of antenna testing technology, and in particular to a multi-point antenna testing platform for magnetic field receiving antennas. Background Technology

[0002] With the rapid development of modern wireless communication technology, magnetic field receiving antennas are increasingly widely used in low-frequency and ultra-low-frequency communication, radio measurement, and geomagnetic detection. Due to their ability to capture low-frequency magnetic field signals, magnetic field receiving antennas exhibit excellent anti-interference performance in complex electromagnetic environments, making them crucial for long-distance signal transmission and weak signal reception. However, to ensure the stable performance of magnetic field receiving antennas in different application scenarios, comprehensive testing and performance optimization are essential. Traditional antenna testing methods primarily employ single-point antenna test platforms, typically relying on signal response measurements within a fixed frequency range. These platforms evaluate the antenna's sensitivity and accuracy by testing its amplitude and phase responses. However, with the continuous expansion of communication frequency ranges, existing test platforms are proving inadequate in handling sensitivity adjustment, phase compensation, and environmental interference avoidance for broadband signals. Furthermore, current technologies often neglect the dynamic impact of external factors such as temperature, humidity, and electromagnetic interference in the test environment on the test results, leading to insufficient accuracy of the test data and thus limiting the optimization potential of magnetic field receiving antenna performance.

[0003] Existing magnetic field receiving antenna testing technologies suffer from the following shortcomings: First, traditional testing platforms mostly rely on signal response analysis within a fixed frequency range, lacking the ability to dynamically scan wideband signals. This makes it difficult to comprehensively capture the amplitude and phase characteristics of the antenna at different frequencies, thus hindering the accurate identification of the optimal operating frequency for optimizing antenna performance. Second, existing platforms lack real-time monitoring and compensation mechanisms for dynamic changes in the testing environment. Especially in complex electromagnetic environments, test results are easily affected by external interference, further reducing sensitivity and the accuracy of phase adjustment. These technical bottlenecks not only limit the accuracy and efficiency of antenna testing but also impede the performance improvement of magnetic field receiving antennas in practical applications.
