Antenna Structure for 4G and 5G Frequency Band Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna structures cannot effectively support the operating frequency band for fifth generation mobile communications technology due to space constraints when miniaturization is required.
Innovation Solution
The antenna structure includes a first radiation member, a second radiation member, and a feeding member, where the radiation members have specific radiation portions and grounding portions electrically connected, allowing for separate and coupled configurations to generate frequency bands applicable to both fourth and fifth generation mobile communications technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional 5G antenna is added to existing products, then 5G operating frequency band support is achieved, but device space is insufficient due to miniaturization requirements
Solution Approach 1:
The patent combines 4G and 5G antenna functions into a single integrated antenna structure. The first radiation member includes both a first radiation portion (for 4G) and a second radiation portion (for 5G), which are electrically connected through a feeding portion. This merging eliminates the need for separate 4G and 5G antennas, resolving the space constraint issue while maintaining both frequency band supports.
Solution Approach 2:
The integrated antenna structure is designed to perform multiple functions: it supports both 4G operating frequency bands (through the first radiation portion) and 5G operating frequency bands (through the second radiation portion). The single antenna structure serves as a universal solution that replaces what would traditionally require multiple separate antennas, thereby achieving multi-functionality within limited space.
2Area of stationary object
If a single antenna structure is used for both 4G and 5G, then space is saved, but radiation efficiency may be compromised
Solution Approach 1:
The radiation members are segmented into distinct functional portions: the first radiation portion for 4G operations and the second radiation portion for 5G operations. Each portion is optimized for its specific frequency band while being electrically connected through the feeding portion. This segmentation allows each part to maintain its radiation efficiency for the intended band while sharing the same physical structure and space.
