Non-contact Antenna with Bent Booster for Strong Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing non-contact data receiving/transmitting bodies face challenges with weak electromagnetic coupling between antennas, making long-distance communication difficult due to the mismatched shapes of the first and second antennas.
Innovation Solution
A non-contact data receiving/transmitting body design featuring a ring-shaped first antenna with at least three straight portions and a second antenna with a central portion bent at angles of 90° or more along the first antenna's portions, with gaps between them less than 2 mm, allowing for strong electromagnetic coupling and extended communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first antenna has a circular ring shape and the second antenna has a shape with three straight portions, then the device structure is simple, but the electromagnetic coupling between the antennas is weak
Solution Approach 1:
The patent applies asymmetry by changing the second antenna from a symmetric three-straight-portions shape to an asymmetric bent shape that follows the curvature of the first antenna. This asymmetric configuration allows the second antenna to be positioned closer to the first antenna along its entire length, significantly improving electromagnetic coupling while maintaining manufacturing simplicity.
Solution Approach 2:
The patent introduces a new spatial dimension by bending the second antenna to follow the curved path of the first antenna. Instead of placing the second antenna in a straight line configuration, it is arranged in a curved dimension that matches the first antenna's geometry, enabling continuous close proximity and strong coupling along the entire antenna length.
2Device complexity
If the second antenna is not arranged along the first antenna, then the device complexity is reduced, but long-distance communication is difficult
Solution Approach 1:
The patent applies curvature by bending the second antenna to follow the circular ring shape of the first antenna. This curved configuration ensures that the second antenna remains in close proximity to the first antenna throughout their interaction, maximizing electromagnetic coupling and enabling long-distance communication without increasing device complexity.
3Ease of manufacture
If gaps between the second antenna and the three straight portions of the first antenna are large, then the ease of assembly is improved, but electromagnetic coupling is weak
Solution Approach 1:
The patent applies segmentation by dividing the second antenna into multiple bent sections that correspond to the three straight portions of the first antenna. Each segment is positioned to closely follow its corresponding portion of the first antenna, maintaining small gaps throughout while preserving manufacturing and assembly simplicity through modular configuration.
Applied Scientific Principles
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 enhances electromagnetic coupling between the antennas, enabling effective long-distance communication by positioning the IC chip adjacent to the second antenna as a power supply point.
Implementation Method 1
the second antenna is used as a booster and resonates with the first antenna in a non-contact manner
Implementation Method 2
the second antenna has a central portion bent so that parts of the central portion extend respectively along the three straight portions of the first antenna and are at an angle equal to or greater than 90° to each other
