Antenna Feeding Structure with Multiple Signal Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing antenna apparatuses have limited operation efficiency due to their fixed size, which is determined by the resonance frequency band, making it difficult to adjust the resonance frequency without increasing the size of the antenna.
Innovation Solution
The antenna apparatus incorporates a feeding structure with multiple signal transferring paths formed by feeding units and ground units, which reduces the reflection coefficient and improves operation efficiency without enlarging the antenna's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric length of the conducting wire is determined corresponding to a resonance frequency band, then the antenna apparatus achieves resonance at the desired frequency band, but the size of the antenna apparatus is fixed and operation efficiency cannot be improved without enlarging the size
Solution Approach 1:
The feeding structure is divided into multiple feeding units and ground units, creating multiple signal transferring paths. This segmentation allows the antenna to maintain a fixed physical size while providing multiple resonant modes through different signal paths, thereby improving operation efficiency across different frequency bands without enlarging the antenna structure.
2Adaptability or versatility
If multiple conductive waves with mutually different lengths are used to expand resonance frequency band, then the resonance frequency band is expanded, but the operation efficiency is deteriorated
Solution Approach 1:
The feeding structure incorporates multiple feeding units and ground units that create dynamically selectable signal transferring paths. By controlling which paths are active, the antenna can adapt to different frequency bands while maintaining high operation efficiency, avoiding the efficiency deterioration associated with using multiple conductive waves of different lengths simultaneously.
3Reliability
If the size of the antenna apparatus is enlarged to improve operation efficiency, then the operation efficiency can be improved, but the antenna apparatus cannot be miniaturized or integrated into compact devices
Solution Approach 1:
The feeding structure with multiple feeding units and ground units serves multiple functions within a single compact antenna apparatus. It provides multiple signal transferring paths that enable the antenna to operate efficiently across different frequency bands, achieving both high operation efficiency and compact size simultaneously by making the feeding structure multi-functional rather than requiring separate antennas for different bands.
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
The multiple signal paths in the feeding structure allow for efficient signal transfer, significantly reducing the reflection coefficient at the resonance frequency band, thereby enhancing the operation efficiency of the antenna without increasing its size.
Implementation Method 1
The antenna apparatus transmits the electromagnetic wave through the conducting wire and the electromagnetic wave forms a standing wave in the conducting wire so that resonance is achieved in the antenna apparatus
Implementation Method 2
The antenna apparatus resonates at a specific frequency band to transmit/receive an electromagnetic wave having a corresponding frequency band
