1Object-affected harmful factors
If MIMO antenna systems use conventional beamforming without polarization adaptation, then beam isolation is insufficient and interference between downlink beams is high, but implementing polarization adaptation increases device complexity
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the polarization state of antenna elements in the MIMO system. The polarization adaptation mechanism modifies the polarization parameter of each antenna element based on channel conditions and interference levels, enabling the system to switch between different polarization states (e.g., horizontal, vertical, diagonal) to achieve beam isolation without requiring complete system redesign. This resolves the contradiction by improving beam isolation through parameter modulation rather than adding complex structural elements.
Solution Approach 2:
The patent implements dynamics by making the polarization configuration of antenna elements changeable and adaptive rather than fixed. The system dynamically reconfigures polarization states in real-time based on detected interference levels and channel characteristics. This dynamic polarization adaptation allows the system to respond to varying operational conditions, achieving effective beam isolation while maintaining manageable complexity through software-controlled parameter changes rather than hardware complexity.
2Reliability
If MIMO antenna systems increase the number of antenna elements to improve beamforming performance, then signal quality improves, but antenna size requirements increase
Solution Approach 1:
The patent applies the dimensionality change principle by introducing polarization as an additional dimension for signal separation. Instead of relying solely on spatial separation (increasing antenna element count and physical distance), the system uses polarization diversity to create orthogonal signal channels. By multiplexing signals across both spatial and polarization dimensions, the system achieves improved signal quality and beamforming performance without proportionally increasing the physical antenna array size, thus resolving the contradiction between reliability and antenna area.
