Existing communication systems face challenges in propagating electromagnetic waves through blocking structures, such as concrete walls, where significant signal loss and disruption occur due to reflection and refraction, preventing efficient wireless communication.
Innovation Solution
A communication device comprising a passive coupling device, a waveguide with high dielectric resonators (HDRs) electromagnetically coupled to transceivers, and a transmitter, where the waveguide is configured to propagate electromagnetic waves around the blocking structure by matching its resonance frequency with the coupling device, allowing efficient capture and reradiation of signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic waves are propagated through blocking structures like concrete walls, then wireless communication can be achieved, but significant signal loss and disruption occur due to reflection and refraction
Solution Approach 1:
The patent introduces a waveguide as an intermediary structure that couples transmitter and receiver antennas. The waveguide, filled with high dielectric resonator materials, mediates the electromagnetic energy transfer between antennas, allowing signals to propagate through blocking structures by guiding waves through the resonator-filled pathway rather than through direct air propagation blocked by walls.
Solution Approach 2:
The patent changes the dielectric parameters of the propagation medium by filling the waveguide with high dielectric resonator materials having specific permittivity values. This parameter change enables the waveguide to support electromagnetic wave propagation at desired frequencies while maintaining signal strength, resolving the contradiction between achieving propagation through blocks and minimizing signal loss.
2Loss of energy
If waveguides with high dielectric resonators are used to propagate electromagnetic waves around blocking structures, then signal strength is maintained and loss is reduced, but device complexity increases
Solution Approach 1:
The patent utilizes the resonator materials as dielectric elements within the waveguide structure. The resonators are distributed throughout the waveguide volume, creating a structured medium that guides electromagnetic waves while maintaining signal strength. This approach achieves energy loss reduction through a structured material arrangement rather than complex active components.
