Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antennas are deployed to achieve multi-beam radiation and improve spectral efficiency, then the spectral efficiency and data transmission capacity are improved, but the device costs and base station space requirements increase
Solution Approach 1:
The patent merges multiple antenna functions into a single integrated antenna structure. The antenna comprises a reflector with multiple independent reflective areas, where each area corresponds to a different feed. This integration allows multiple beams to be generated from one physical antenna, reducing the space and cost compared to deploying multiple separate antennas while maintaining the spectral efficiency benefits of multi-beam radiation
Solution Approach 2:
The patent segments the reflector surface into multiple independent reflective areas, where each area is associated with a specific feed. This segmentation allows each feed to independently control a specific reflective area, enabling independent beam formation. The segmented structure achieves multi-beam radiation capability within a single antenna, resolving the contradiction between maintaining multiple antenna functions and reducing physical space requirements

This integration allows multiple beams to be generated from one physical antenna, reducing the space and cost compared to deploying multiple separate antennas while maintaining the spectral efficiency benefits of multi-beam radiation
Solution Approach 2:
The single antenna structure performs multiple functions that would traditionally require separate antennas. The reflector with multiple segmented areas can simultaneously generate multiple independent beams for different communication functions (e.g., different users, different frequency bands, or different beam directions). This multi-functionality reduces device costs by eliminating the need for multiple separate antenna systems
3Adaptability or versatility
If multiple antennas are deployed to achieve independent multi-beam radiation, then the beam independence and data stream capacity are improved, but the base station space occupied increases
Solution Approach 1:
The patent segments the reflector surface into multiple independent reflective areas, where each area is associated with a specific feed. This segmentation allows each feed to independently control a specific reflective area, enabling independent beam formation. The segmented structure achieves multi-beam radiation capability within a single antenna, resolving the contradiction between maintaining multiple antenna functions and reducing physical space requirements
Solution Approach 2:
The patent transitions from a traditional three-dimensional spatial arrangement of multiple separate antennas to a two-dimensional segmented reflector surface. By utilizing the surface area of the reflector in a planar configuration with multiple segmented zones, the system achieves multi-beam independence without requiring vertical or horizontal stacking of multiple antenna volumes, thus minimizing base station space occupation

AI summary
Embodiments of this application provide an antenna and an antenna system. As the antenna is functionally equivalent to a plurality of conventional antennas, device costs and base station space occupied by the antenna can be reduced. The antenna includes a first reflective surface and N feeds, where N is an integer greater than 1. The N feeds are disposed on the first reflective surface, the first reflective surface includes N areas, the N areas are in one-to-one correspondence with the N feeds, and each area is used to reflect a beam radiated by a corresponding feed.
