Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional short range wireless communication systems experience degradation in transmission characteristics due to the size and shape of the ground plane in receiver couplers, leading to decreased signal quality and inability to perform high-speed data transmission.
Innovation Solution
The communication apparatus includes a coupling conductor and a ground conductor with the ground conductor being smaller in area than the coupling conductor, improving transmission characteristics by reducing the ground plane's effect on the coupling conductors, and adjusting the lengths of the ground plane and power supply paths to enhance cutoff frequencies.

Engineering Contradiction Analysis
1Reliability
If a conventional ground plane configuration is used in receiver couplers, then the structure is simple and easy to manufacture, but transmission characteristics are degraded and signal quality decreases
Solution Approach 1:
The patent applies parameter changes by modifying the area of the ground conductor relative to the coupling conductor. Specifically, the ground conductor area is set to be smaller than the coupling conductor area (area ratio < 1), which optimizes the transmission characteristics and signal quality without requiring complex structural modifications.
2Productivity
If the ground conductor area is reduced, then transmission characteristics improve by about 6 dB and cutoff frequencies increase, but the design becomes more constrained
Solution Approach 1:
The patent defines a specific parameter range for the area ratio between ground conductor and coupling conductor (area ratio < 1), which enables high-speed data transmission up to 2 Gbps. This parameter optimization balances performance improvement with manufacturability constraints.
