Split Ring Antenna Reinforcement for Deformation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Antennas with split ring resonators face deformation and attitude variation issues when subjected to external forces due to inadequate fixation, leading to unstable characteristics when mounted on circuit boards.
Innovation Solution
The antenna design incorporates additional reinforcing portions and fixed portions that extend from the upper surface of the split ring resonator, allowing for secure mounting at three points on the circuit board, preventing excessive deformation and maintaining constant characteristics while resisting external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the number of fixed portions is increased to four or more points, then the deformation of the antenna is prevented, but the antenna has great variation in its attitude upon mounting on the circuit board, resulting in unstable characteristics
Solution Approach 1:
The antenna structure is segmented into distinct functional portions: three fixed portions for mounting, two reinforcing portions for deformation resistance, and a main portion for radiation. This segmentation allows each portion to perform its specific function optimally without interfering with others, resolving the contradiction between deformation prevention and attitude stability.
Solution Approach 2:
Different portions of the antenna are given different local qualities: the fixed portions are designed for secure mounting with appropriate spacing, the reinforcing portions are positioned specifically to resist deformation forces, and the main portion maintains its radiation characteristics. This localized optimization allows the antenna to achieve both deformation resistance and attitude stability.
2Reliability
If the main portion is made larger to improve radiation characteristics, then the antenna performance is enhanced, but the antenna becomes more susceptible to deformation under external force
Solution Approach 1:
The antenna is divided into a main portion for radiation and separate reinforcing portions for mechanical strength. This segmentation allows the main portion to be optimized for radiation characteristics without compromising mechanical strength, as the reinforcing portions bear the mechanical loads.
Solution Approach 2:
The reinforcing portions are merged with the main portion through controlled connections, creating a unified structure where the reinforcing portions provide mechanical support while allowing the main portion to maintain its radiation optimization. This merging ensures both radiation performance and deformation resistance.

AI summary
An antenna comprises a split ring resonator. The antenna has a main portion which forms a split ring with a split portion. The main portion has an upper surface portion, a first fixed portion, a second fixed portion, a third fixed portion, a first reinforcing portion, a second reinforcing portion, a feed portion, a first end portion and a second end portion. Each of the first fixed portion, the second fixed portion and the third fixed portion is fixed on a circuit board when the antenna is mounted on the circuit board. Lower ends of the first fixed portion, the second fixed portion and the third fixed portion define an imaginary plane perpendicular to an up-down direction. Each of lower ends of the first reinforcing portion, the second reinforcing portion and the feed portion is positioned between the upper surface portion and the imaginary plane in the up-down direction.
