Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed beams are formed by using an analog split architecture, then antenna network deployment complexity is reduced, but beam adjustment flexibility is reduced
Solution Approach 1:
The patent introduces adjustable phase shifters that can dynamically change phase values to switch between different beam groups. This dynamic adjustment capability allows the fixed beam architecture to adapt to different communication scenarios while maintaining the simplified analog split structure, thus resolving the contradiction between deployment complexity and beam adjustment flexibility.
Solution Approach 2:
The patent changes the phase parameter of the phase shifters to generate different beam groups. By adjusting the phase value (e.g., 0° or 180° for 1-bit phase shifters), the system can switch between beam groups without changing the physical antenna structure, thereby maintaining low deployment complexity while achieving beam adjustment flexibility.
2Adaptability or versatility
If antenna elements are spaced by M antenna elements in each row, then multiple beam groups can be generated, but antenna array structure complexity increases
Solution Approach 1:
The patent segments the antenna array into multiple rows with antenna elements spaced by M positions. This segmentation creates natural groups of antenna elements that can be controlled by phase shifters to form different beam groups. The segmentation approach allows systematic generation of multiple beam groups while maintaining a regular, manageable structure.
Solution Approach 2:
The spaced antenna element structure serves multiple functions: it enables generation of multiple beam groups, maintains a regular grid layout for ease of implementation, and works with simple phase shifters. The same structural pattern can generate different numbers of beam groups by adjusting M and the number of phase shifters, providing universal applicability.

AI summary
This application discloses an antenna apparatus, including an antenna array and an adjustable phase shifter. In each row of antenna elements in the antenna array, antenna elements on a same radio frequency RF channel are spaced by M antenna elements, where M is used to determine a quantity of beams in a first beam group and a quantity of beams in a second beam group, and M is an integer greater than 1. When the adjustable phase shifter is at a first angle, the first beam group is obtained; or when the adjustable phase shifter is at a second angle, the second beam group is obtained. This application discloses a beam adjustment method. In this application, a plurality of beams can be formed in a horizontal direction, and the beams are grouped by using an adjustable phase shifter, thereby effectively improving beam adjustment flexibility.
