Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If communication frequency bands increase to provide expanded performance, then access speed and data rate improve, but propagation loss and noise factors increase
Solution Approach 1:
The patent combines the RFIC and antenna into a single integrated module, reducing the physical separation between transmitter and radiator. This integration minimizes transmission losses in the feeding network and improves power efficiency by eliminating separate connectors and transition structures that cause signal degradation at millimeter wave frequencies.
Solution Approach 2:
The antenna module is designed to support multiple frequency bands and communication standards (4G, 5G, WiGig) within a single integrated structure. The dual-type antenna elements can operate across different frequency ranges, providing universal functionality that maintains performance across varying frequency conditions without requiring separate antenna systems for each band.
2Reliability
If antenna gain is boosted to achieve stabilized access, then communication stability improves, but power efficiency deteriorates
Solution Approach 1:
By integrating the RFIC directly with the antenna elements, the patent eliminates the need for separate high-gain amplifiers and complex feeding networks that consume excessive power. The close proximity allows efficient power transfer and enables the system to achieve stable communication through optimized near-field coupling rather than through high-power amplification.
Solution Approach 2:
The patent employs polarization-agile phased-array technology that dynamically adjusts beamforming parameters and polarization states to optimize signal quality. By changing the electrical parameters (phase, amplitude, polarization angle) of the antenna elements, the system achieves stable access through adaptive beam steering and focusing rather than through brute-force power increases.
3Reliability
If wide beam forming and beam scanning range are implemented for stabilized access, then access stability improves, but directivity decreases as frequency band rises
Solution Approach 1:
The patent implements a polarization-agile phased-array system that dynamically adjusts beam direction, width, and polarization state in real-time. The dual-type antenna elements can independently control horizontal and vertical polarization components, enabling dynamic beam steering across wide angular ranges while maintaining appropriate directivity for each scanning position through adaptive phase and amplitude weighting.
Solution Approach 2:
The antenna array is divided into multiple independently controllable dual-type elements arranged in a phased-array configuration. Each element can be individually phased and polarized controlled, allowing the system to synthesize wide beam patterns through constructive interference while maintaining the ability to focus energy in specific directions when needed, thus achieving both wide scanning range and directional focus.
4Volume of moving object
If compact design is pursued for easy integration, then device size reduces, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the RFIC, power feeding lines, and antenna elements into a single monolithic module fabricated using standard PCB and RFIC manufacturing processes. This consolidation reduces the overall device volume by eliminating separate mounting brackets, connectors, and alignment fixtures, while the modular design allows the integrated unit to be manufactured using existing industrial processes without requiring complex custom fabrication.
