Solution Overview
Problem
Conventional electronic devices using waveguides face inefficiencies due to the need for splitter and combiner circuits, which increase power consumption, occupy device area, and reduce efficiency, especially when amplifying signals for transmission.
Innovation Solution
The use of a half-patch launcher system, where a conductive patch on a dielectric layer interacts with a waveguide to generate a transmission signal, potentially eliminating the need for separate combiner circuits by using the waveguide as a coherent combiner and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If splitter and combiner circuits are used to amplify signals, then signal transmission capability is improved, but power consumption increases and device area increases
Solution Approach 1:
The patent combines the functions of signal splitting, amplification, and combining into a single integrated waveguide structure. Multiple amplifiers are positioned within the waveguide to directly amplify signals as they propagate, eliminating the need for separate splitter and combiner circuits. This merging of functions reduces power consumption while maintaining signal transmission capability.
Solution Approach 2:
The waveguide structure serves multiple functions simultaneously: it acts as the signal transmission medium, houses the amplifiers, provides signal splitting through its geometry, and performs signal combining. This multi-functionality eliminates the need for dedicated splitter and combiner components, reducing overall power consumption and device area.
2Power
If splitter and combiner circuits are used to amplify signals, then signal transmission capability is improved, but device area increases
Solution Approach 1:
The patent merges the splitter, amplifiers, and combiner functions into a single integrated waveguide structure. The waveguide's physical geometry provides signal splitting, while amplifiers positioned within the same structure perform amplification and combining functions. This integration dramatically reduces the device area compared to separate discrete circuits.
Solution Approach 2:
The amplifiers are nested within the waveguide structure, with multiple amplifier elements positioned inside the waveguide's propagation path. This nesting arrangement allows the amplifiers to share the waveguide's physical space, eliminating the need for separate housing and reducing overall device area.
3Reliability
If multiple amplifiers are used to reduce loss effects, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
Multiple amplifiers are merged into a single integrated waveguide structure, where they collectively provide signal transmission quality improvement through distributed amplification. The waveguide's geometry naturally manages the coordination between multiple amplifiers, reducing the control complexity that would otherwise be required to manage multiple separate amplifier circuits.
