Innovation Solution
The antenna structure incorporates a plurality of antenna arrays with via holes, where each antenna unit is embedded in the housing and connected via a flexible printed circuit board, with a ground circuit, control circuit, and feed source to enhance signal transmission and reception, allowing for increased antenna units in a compact space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more antenna elements are added to increase transmission rates for 5G communication, then the communication performance is improved, but the device area and weight increase
Solution Approach 1:
The patent embeds multiple antenna elements within a limited substrate area by nesting them in a compact arrangement. The antenna elements are integrated into the housing structure with via holes passing through the housing to connect antenna units, allowing dense packing of multiple antenna elements without proportionally increasing the overall device area.
Solution Approach 2:
The patent utilizes three-dimensional space by extending antenna elements in multiple directions and layers. Via holes are arranged in specific patterns that allow antenna units to be positioned at different depths and orientations, effectively using vertical and lateral dimensions simultaneously to accommodate more antenna elements within the same footprint.
2Productivity
If more antenna elements are added to increase transmission rates for 5G communication, then the communication performance is improved, but the device weight increases
Solution Approach 1:
The patent employs a flexible printed circuit board (FPCB) to support and interconnect multiple antenna elements. The FPCB is a thin, lightweight flexible substrate that can be bent and shaped to accommodate antenna configurations without adding significant weight, unlike rigid traditional PCBs.
Solution Approach 2:
The patent integrates antenna elements directly into the housing structure, combining the housing material with antenna functionality. The housing serves dual purposes as both structural protection and antenna support, eliminating the need for separate heavy antenna substrates and reducing overall device weight.
3Quantity of substance
If antenna elements are embedded in housing with via holes to increase density, then the antenna density is improved, but the device becomes more vulnerable to impacts and abrasions
Solution Approach 1:
The patent incorporates via holes that pass through the housing with antenna units positioned within the housing cavity. This nested structure provides inherent protection where the housing material acts as a cushioning layer that absorbs and distributes impact forces, protecting the embedded antenna elements from direct mechanical damage.
Solution Approach 2:
The antenna units are nested within the housing structure, with the housing serving as a protective outer shell. This nesting arrangement naturally protects the delicate antenna elements from external impacts and abrasions, as any mechanical stress first encounters the robust housing material before reaching the sensitive antenna components.
