Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate antennas are arranged for different frequency bands, then the needs of different regions and user groups are met, but the antenna integration and miniaturization are not conducive, and the base station cost increases
Solution Approach 1:
The patent combines multiple separate antennas into a single integrated antenna structure that supports multiple frequency bands (low band 703-960MHz and high band 1710-2690MHz). The antenna includes a reflector, radiator, and multiple parasitic elements that work together to provide both low band and high band coverage, eliminating the need for separate antenna installations.
Solution Approach 2:
The antenna is designed as a universal multi-functional device that can operate across multiple frequency bands simultaneously. The low band radiator and high band radiating elements are integrated into one structure that serves dual purposes: providing low frequency coverage for broad area service and high frequency coverage for capacity enhancement, all from a single antenna unit.
2Adaptability or versatility
If multiple separate antennas are arranged for different frequency bands, then the needs of different regions and user groups are met, but the antenna site resources are not alleviated, and the base station cost increases
Solution Approach 1:
The patent merges multiple separate antenna systems into one integrated antenna structure. Instead of installing separate low band antennas and high band antennas, the invention provides a single antenna that incorporates both low band radiating elements and high band radiating elements, thereby reducing the total number of antennas required at each base station site.
3Adaptability or versatility
If high frequency radiating element arrays are arranged on both flat and bending members, then flexible combination of antenna arrays is achieved, but the structural complexity increases
Solution Approach 1:
The antenna structure is segmented into distinct functional components: a reflector, a low band radiator, high band radiating elements arranged on flat members, and additional high band radiating elements on bending members. This segmentation allows each component to be optimized for its specific frequency band while maintaining overall structural coherence and facilitating assembly.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by placing high band radiating elements on both flat horizontal members and bending diagonal members. This multi-dimensional configuration enables flexible beam forming and signal coverage optimization in different spatial directions, enhancing the antenna's adaptability for various deployment scenarios.
