Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-layered magneto-electric dipole antenna is manufactured using complex process, then antenna performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent transitions from a conventional multi-layered three-dimensional structure to a planar two-dimensional structure where all patches are disposed on the same plane. This dimensional simplification reduces manufacturing complexity while maintaining the magneto-electric dipole antenna's radiation performance through careful design of patch geometries and via configurations in the planar arrangement.
Solution Approach 2:
The patent combines multiple functional elements (patches, ground structures, and feeding mechanisms) into a single planar layer rather than distributing them across multiple layers. This merging approach simplifies the manufacturing process by eliminating the need for complex multi-layer stacking and alignment, while the magneto-electric dipole characteristics are achieved through the specific geometric arrangement of these combined elements.
2Reliability
If multi-layered magneto-electric dipole antenna is manufactured using complex process, then antenna performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent reduces structural complexity by flattening the multi-layered three-dimensional configuration into a two-dimensional planar structure. All patches are arranged on the same plane, eliminating the need for vertical stacking of multiple layers, which significantly simplifies the overall device structure while preserving the essential magneto-electric dipole radiation mechanism through planar geometric design.
Solution Approach 2:
The patent merges multiple separate layers into a single planar structure, combining what would traditionally require multiple fabrication steps and layer alignments into one integrated plane. This reduces device complexity by eliminating inter-layer connections and simplifying the structural hierarchy, while the functional performance is maintained through optimized in-plane element arrangements.

Function Achieved in This Case
The simplified structure allows for cost-effective manufacturing of magneto-electric dipole antennas and arrays, maintaining performance in the Ka-band with improved gain and isolation characteristics.
Implementation Method 1
The vias and the sector patches form magneto-electric dipoles. When two signals are respectively fed to the first feed-in line and the second feed-in line, the signals are transmitted respectively to the first feed-out line and the second feed-out line respectively through the first feed-out probe and the second feed-out probe, and two electromagnetic waves are radiated.

AI summary
In a magneto-electric dipole antenna, first to third substrates are stacked from top to bottom. A ground layer is disposed between the second and third substrates. Four sector patches and a first feed-out line are disposed on the first substrate. Four ground plates and first and second feed-in lines are disposed below the third substrate. Each of four vias penetrates the second and third substrates and the ground layer. A second feed-out line is disposed between the first and second substrates. Each of first and second feed-out probes penetrates the first to third substrates and the ground layer. The nth feed-out probe is connected to the nth feed-in line and the nth feed-out line, where 1≤n≤2. When two signals are fed to the feed-in lines, the signals are transmitted to the feed-out lines through the feed-out probes, and two electromagnetic waves are radiated.
