Engineering Contradiction Analysis
1Area of stationary object
If the antenna size is reduced to meet footprint constraints, then the antenna can be deployed in space-constrained applications, but the bandwidth and transmission capabilities are limited
Solution Approach 1:
The antenna system divides the radiating structure into multiple independent radiating elements arranged in an array configuration. Each element can be individually controlled through the feed network, allowing the compact antenna to achieve enhanced bandwidth and transmission capabilities through coherent signal combination across multiple elements, effectively resolving the contradiction between small footprint and high adaptability
Solution Approach 2:
The patent employs a three-dimensional meta-structure configuration with radiating elements arranged in multiple layers and dimensions. This spatial arrangement allows the compact antenna to achieve enhanced radiation patterns, beam forming capabilities, and frequency bandwidth without increasing the overall footprint, thereby resolving the contradiction between size constraints and transmission capabilities
2Ease of manufacture
If the antenna configuration is simplified to reduce manufacturing complexity, then the manufacturing cost decreases, but the control capabilities and beam steering precision are reduced
Solution Approach 1:
The feed network is designed as a universal structure that can simultaneously perform multiple functions: power distribution to all radiating elements, phase control for beam steering, and amplitude control for beam forming. This multi-functional design achieves precise control capabilities without requiring separate complex control mechanisms for each function, thereby resolving the contradiction between manufacturing simplicity and control precision
Solution Approach 2:
The antenna system incorporates variable phase shifters and amplitude control mechanisms in the feed network that can dynamically adjust the phase and amplitude of signals fed to each radiating element. This dynamic control capability enables precise beam steering and forming while maintaining a relatively simple overall structure, resolving the contradiction between manufacturing ease and operational control
3Adaptability or versatility
If the frequency bandwidth is increased to improve adaptability, then the antenna can operate across multiple frequency bands, but the signal power distribution becomes uneven across frequencies
Solution Approach 1:
The patent incorporates an adaptive compensation module that uses feedback mechanisms to detect the operating frequency and automatically adjusts the power distribution across the feed network. When the antenna operates at frequencies away from the center frequency, the feedback system activates compensation mechanisms to restore uniform power distribution, thereby resolving the contradiction between wide frequency coverage and power uniformity
Solution Approach 2:
The feed network incorporates frequency-dependent parameter adjustments through variable components such as phase shifters and attenuators whose characteristics change with frequency. These parameter changes are designed to compensate for frequency-induced power distribution variations, enabling the antenna to maintain uniform signal power across a wide frequency bandwidth while preserving frequency adaptability
