Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication modules with planar antenna structures face limitations in meeting the requirements of 5G systems due to restricted wiring space and difficulty in miniaturization, as they cannot provide the necessary electrical functions for high-frequency operations and are hindered by increased width when attempting to enhance antenna configurations for improved signal quality and transmission speed.
Innovation Solution
The electronic package incorporates a substrate with recesses of varying depths on one surface and corresponding antenna layers on the other, electromagnetically coupled to antenna feed lines, allowing for adjustable electromagnetic coupling distances and improved radiation efficiency, enabling the transmission of multiple frequencies within a predetermined size, thus meeting the demands of 5G systems while minimizing module size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the layout area on the substrate surface is increased to form multi-frequency antenna bodies, then the antenna configuration capability is improved, but the module width increases and miniaturization is hindered
Solution Approach 1:
The patent transitions from planar two-dimensional antenna layout to three-dimensional stacked configuration. Multiple antenna bodies are formed at different heights above the substrate surface, enabling multi-frequency operation without increasing the substrate footprint. This vertical dimensionality change resolves the contradiction between antenna configuration capability and module width.
Solution Approach 2:
The patent implements nested antenna structures where smaller antenna bodies are positioned within or adjacent to larger ones in the vertical stacking arrangement. This nesting enables multiple antenna functions to coexist in a compact space, improving adaptability while maintaining compact module dimensions.
2Adaptability or versatility
If the substrate width is increased to accommodate more wiring layers, then the electrical functions for 5G operation are improved, but the module size increases
Solution Approach 1:
The patent moves wiring and antenna structures from a planar layout to a three-dimensional stacked configuration. Multiple wiring layers and antenna bodies are arranged vertically, enabling enhanced electrical functionality for 5G operation without increasing the module's footprint or overall volume.
3Ease of manufacture
If the antenna structure is made planar with fixed substrate dimensions, then the fabrication is simplified, but the wiring space and antenna functions are limited
Solution Approach 1:
The patent segments the antenna structure into multiple independent antenna bodies formed at different heights. Each antenna body can be independently designed and fabricated, maintaining fabrication simplicity while enabling diverse antenna functions through the stacked configuration.
