Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antenna designs are used for extremely high frequencies, then device integration is achieved, but path loss increases and directionality is lost
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements arranged in arrays, with each element contributing to the overall beamforming capability. This segmentation allows individual elements to be optimized while collectively achieving directionality and reduced path loss through coherent signal combination.
Solution Approach 2:
Multiple antenna elements are combined into integrated arrays that work together to form directed beams. The merging of multiple signal paths with controlled phase and amplitude relationships creates constructive interference in desired directions, thereby reducing effective path loss and improving signal reliability.
2Reliability
If conventional antenna designs are used for extremely high frequencies, then device integration is achieved, but signal directionality is lost
Solution Approach 1:
The antenna system employs dynamic beamforming capabilities where the radiation pattern can be electronically steered and adjusted in real-time. By dynamically controlling the phase and amplitude of each antenna element, the system adapts to different communication scenarios and maintains optimal directionality without mechanical movement.
Solution Approach 2:
The system changes the electrical parameters (phase, amplitude, frequency) of individual antenna elements to control the overall radiation pattern. By adjusting these parameters, the beam direction and shape can be modified to achieve desired directionality for different operational requirements.
3Power
If multiple antennas are loaded into the same area, then signal concentration in specific direction is achieved, but device space is reduced
Solution Approach 1:
Antenna elements are arranged in three-dimensional configurations and multi-layer structures, utilizing vertical and lateral dimensions simultaneously. This dimensional approach allows multiple antennas to be packed into compact volumes while maintaining their individual radiation patterns and enabling beamforming capabilities through spatial diversity.
