Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current single path antenna structures exhibit suboptimal high and low frequency efficiencies, indicating a need for improved designs that enhance signal transmission and reception capabilities.
Innovation Solution
The antenna structure incorporates a radiation portion with a loop segment, high frequency segment, and low frequency segment, forming dual-paths and a frequency adjusting portion to optimize signal propagation, along with a coupling portion for increased high frequency efficiency and a grounding dual-path for improved low frequency efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single path antenna structure is used, then the device complexity is reduced, but the high frequency efficiency and low frequency efficiency deteriorate
Solution Approach 1:
The radiation portion is segmented into multiple functional segments: loop segment, high frequency segment, and low frequency segment. This segmentation allows the antenna to create separate current paths for different frequency ranges, improving efficiency at both high and low frequencies while maintaining a unified structural design
Solution Approach 2:
The patent transitions from a single-dimensional current path to a multi-dimensional dual-path structure. By introducing the loop segment that connects to the grounding portion, the antenna creates two distinct current paths (first and second paths) that operate simultaneously, enabling improved performance across different frequency bands
2Ease of manufacture
If a single path antenna structure is used, then the manufacturing process is simplified, but the signal transmission and reception capabilities deteriorate
Solution Approach 1:
The radiation portion is divided into distinct segments (loop segment, high frequency segment, low frequency segment) that can be manufactured separately and then assembled, maintaining manufacturing simplicity while achieving enhanced signal transmission and reception capabilities through the dual-path configuration
Solution Approach 2:
The antenna structure is designed to perform multiple functions simultaneously: it supports both high frequency and low frequency operations, provides dual current paths for improved signal capability, and maintains a unified grounding system, all within a single manufacturable structure

AI summary
An antenna structure, used for being fed with a signal, includes a grounding portion, a radiation portion, and a frequency adjusting portion. The radiation portion has a loop segment, a high frequency segment, and a low frequency segment. The loop segment has a feeding sub-segment adjacent to the grounding portion and used for being fed with the signal. The high and low frequency segments are extended from opposite ends of the loop segment away from each other. The frequency adjusting portion is connected to the loop segment and the grounding portion. A high frequency dual-path is formed from a feeding point of the feeding sub-segment and extends along the loop segment in two different directions to the high frequency segment. A low frequency dual-path is formed from the feeding point and extends along the loop segment in two different directions to the low frequency segment.
