Antenna Structure for 5G Band Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antenna structures are insufficient for supporting the operating frequency band of 5G mobile networks due to design constraints related to miniaturization, which limits the integration of additional 5G antennas.
Innovation Solution
The antenna structure incorporates specific radiation elements and a feeding element with defined distances and configurations, allowing for the generation of an operating frequency band between 617 MHz and 698 MHz by optimizing the separation and coupling of radiation portions and the feeding point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 5G antenna is additionally added to support the operating frequency band of 5G, then the frequency band coverage is improved, but the device size increases and space availability decreases
Solution Approach 1:
The patent combines 4G and 5G antenna functions into a single integrated antenna structure. The first radiation element and second radiation element share common feeding portions and grounding portions, allowing the antenna to support both 4G frequency bands (e.g., 700 MHz, 1800 MHz) and 5G frequency bands (e.g., 28 GHz) without requiring separate antenna installations, thus maintaining compact device size while achieving multi-band coverage
Solution Approach 2:
The antenna structure is designed with multi-functional capability to support multiple frequency bands and network generations. By configuring radiation elements with specific length ratios (e.g., L1/L2 between 0.2-0.8) and using shared feeding networks, the same antenna structure can operate across 4G LTE and 5G NR frequency bands, eliminating the need for separate dedicated antennas for each network type
2Volume of moving object
If the antenna structure is miniaturized to meet current product design requirements, then the device size is reduced, but the ability to add additional 5G antenna elements is lost
Solution Approach 1:
The antenna design embeds multiple functional elements within a compact structure. The first and second radiation elements are positioned adjacent to each other and share common feeding portions and grounding portions, creating a nested-like configuration where multiple antenna functions are contained within a single compact antenna body, achieving miniaturization without sacrificing 5G capability
Solution Approach 2:
The patent utilizes spatial arrangement in multiple dimensions to achieve compact design. The radiation elements, feeding portions, and grounding portions are configured in specific spatial relationships (e.g., adjacent positioning, specific length ratios) that enable multi-frequency operation within a reduced volume, transitioning from linear expansion to multi-dimensional optimization

AI summary
An antenna structure is provided. The antenna structure includes a first radiation element, a second radiation element, and a feeding element. The first radiation element includes a first radiation portion, a second radiation portion, and a feeding portion. The second radiation element includes a third radiation portion, a fourth radiation portion, and a grounding portion. The third radiation portion and the first radiation portion are separate from each other and coupled to each other, the third radiation portion and the second radiation portion are separate from each other and coupled to each other, and the fourth radiation portion and the first radiation portion are separate from each other and coupled to each other. The feeding element is electrically connected with the feeding portion and the grounding portion. A junction between the feeding element and the feeding portion is defined as a feeding point.
