Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If metal transmission lines are used to connect high frequency transceiver devices, then the connection is mechanically robust, but the system becomes bulky, expensive, and experiences large damping especially above 100 GHz
Solution Approach 1:
The patent changes the fundamental parameter of waveguide material from metal to dielectric material. This parameter change enables lower signal loss at high frequencies (above 100 GHz) while the cone/p pyramid structure provides the necessary coupling mechanism, resolving the contradiction between signal loss and coupling complexity
Solution Approach 2:
The patent introduces a dielectric waveguide as an intermediary component between the high frequency transceiver device and the antenna system. This intermediary enables efficient signal transmission with reduced damping while the cone/p pyramid coupling structure provides the interface, solving both the signal loss and coupling complexity issues
2Loss of energy
If dielectric waveguides are used to guide mmW or Terahertz signals, then signal transmission performance is improved, but the coupling between high-frequency components and dielectric waveguides becomes complicated
Solution Approach 1:
The patent introduces a dielectric waveguide as an intermediary component between the high frequency transceiver device and the antenna system. This intermediary enables efficient signal transmission with reduced damping while the cone/p pyramid coupling structure provides the interface, solving both the signal loss and coupling complexity issues
3Reliability
If beam steering antennas are used to couple signals between radiating chips and dielectric waveguides, then signal coupling is achieved, but the system becomes complicated and expensive due to complex antenna systems and steering electronics
Solution Approach 1:
The patent extracts and eliminates the complex beam steering electronics and control systems from the coupling mechanism. Instead, it uses a passive dielectric waveguide with a simple cone/p pyramid structure to achieve signal coupling, maintaining reliability while dramatically reducing system complexity and cost
Solution Approach 2:
The patent introduces a dielectric waveguide as an intermediary component between the high frequency transceiver device and the antenna system. This intermediary enables efficient signal transmission with reduced damping while the cone/p pyramid coupling structure provides the interface, solving both the signal loss and coupling complexity issues
