Non-Parallel Plane Electrode Connections for RF Amplifier Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices, such as radio frequency amplifiers, suffer from electromagnetic coupling between connections, leading to unwanted feedback and deterioration of transfer characteristics.
Innovation Solution
The use of non-parallel planes for the connections, with at least one connection forming part of an impedance transforming network, reduces electromagnetic coupling by positioning the largest part of the first connection in a first plane and the largest part of the second connection in a second plane, which are non-parallel, and optionally incorporating a loop shape to further minimize coupling.

Engineering Contradiction Analysis
1Object-affected harmful factors
If connections are arranged in parallel planes, then electromagnetic coupling between connections increases, but device size can be reduced
Solution Approach 1:
The patent applies dimensionality change by transitioning from two-dimensional parallel plane arrangement to three-dimensional non-parallel plane configuration. The first connection is arranged in a first plane while the second connection is arranged in a second plane that is non-parallel to the first plane, thereby utilizing the third spatial dimension to reduce electromagnetic coupling between connections while maintaining compact device dimensions.
2Reliability
If connections are separated to reduce electromagnetic coupling, then unwanted feedback is reduced, but device complexity increases
Solution Approach 1:
The patent applies asymmetry by arranging connections in non-parallel planes rather than symmetric parallel planes. The first connection is positioned in a first plane and the second connection in a second plane that is non-parallel to the first, creating an asymmetric spatial configuration that reduces electromagnetic coupling and unwanted feedback while maintaining manageable device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces electromagnetic coupling, minimizes unwanted feedback, allows electrodes to be closer and on the same side, and enables smaller, more cost-effective packaging, particularly beneficial in high-frequency environments.
Implementation Method 1
an electromagnetic coupling may be present between the first and second connections. Such an electromagnetic coupling may introduce an unwanted feedback. The first and second planes are non-parallel planes for reducing an electromagnetic coupling between the first connection and the second connection
