研究目的
To analyze the relationship between the variation of the antenna resonance frequency and the reflection coefficient in massive MIMO antenna array modules for 5G mmW radio products.
研究成果
The PDF of the antenna reflection coefficient at the specification limit is a non-linearly scaled mirrored version of the PDF of the variation of the antenna resonance. There is a good correlation between the measured and the simulated PDFs, indicating the reliability of the simulation model. The quality level of massive MIMO antenna arrays is determined by the worst-performing antenna, necessitating stricter design targets for individual antennas as the number of antennas in the module increases.
研究不足
The study focuses on the variation of antenna resonance frequency and its impact on the reflection coefficient, but does not extensively cover other factors that might affect antenna performance in real-world applications.
