Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple Hermite-Gaussian and Laguerre-Gaussian beams are transmitted separately, then transmission reliability is maintained, but data throughput is limited
Solution Approach 1:
The antenna array is segmented into multiple layers, with each layer containing multiple patch antennas that can independently transmit different Hermite-Gaussian and Laguerre-Gaussian beams. This segmentation allows simultaneous transmission of multiple modes, increasing data throughput while maintaining manageable complexity through modular design
Solution Approach 2:
The patent transitions from a single-plane antenna arrangement to a three-dimensional multi-layer structure. By stacking antenna layers at different heights (z-dimension) with inter-layer spacing, the system can transmit multiple orthogonal beams simultaneously, effectively utilizing spatial dimensionality to increase capacity without proportionally increasing horizontal footprint
2Adaptability or versatility
If multiple beams are multiplexed into a single signal, then bandwidth is increased, but signal interference may occur
Solution Approach 1:
Each patch antenna in the array is configured with specific local characteristics including distinct amplitude weights and phase shifts tailored to its position and function. This local customization allows each antenna element to contribute uniquely to the overall beamforming, enabling precise control over multiplexed signal characteristics and minimizing interference between different Hermite-Gaussian and Laguerre-Gaussian modes
Solution Approach 2:
The system dynamically adjusts transmission parameters including amplitude distribution, phase progression, and frequency allocation across different antenna layers and elements. By changing these parameters according to the specific Hermite-Gaussian and Laguerre-Gaussian modes being transmitted, the system optimizes multiplexing efficiency and maintains signal integrity throughout the transmission channel

AI summary
A multi-level antenna array includes a plurality of patch antennas. Each layer of a plurality of layers is separated from other layers by a distance and support a portion of the plurality of patch antennas. Each of a plurality of connectors is associated with one of the plurality of layers for supplying a signal for transmission by the associated layer. A feed network on each of the plurality of layers provides a connection between a connector of the plurality of connectors associated with the layer and the portion of the plurality of patch antennas located on the layer. Each layer of the plurality of layers transmits the signal having a different orthogonal function applied thereto and multiplexes each of the signals having the different orthogonal function applied thereto onto a single transmission beam.
