Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern apparatus face challenges in finding optimal locations for multiple antenna systems that cover multiple frequency bands.
Innovation Solution
An antenna arrangement is designed with dielectric substrates and conductive portions that are positioned within the apparatus' rim, allowing for separate feeding of antenna elements and slot antennas, with overlapping and non-overlapping configurations to optimize frequency operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antenna systems are implemented to cover multiple frequency bands, then frequency coverage is improved, but device complexity increases
Solution Approach 1:
The patent combines high-frequency and low-frequency antenna systems into a single integrated antenna arrangement. The dielectric substrate integrates both antenna types in one structure, with feed arrangements that can separately excite either the high-frequency elements or the low-frequency slot, eliminating the need for separate antenna assemblies and reducing overall system complexity.
Solution Approach 2:
The integrated antenna arrangement serves multiple functions: it can operate as a high-frequency antenna system, a low-frequency antenna system, or both simultaneously. The single structure with dual feed arrangements provides universal coverage for multiple frequency bands, allowing the same physical antenna to adapt to different operational requirements.
2Adaptability or versatility
If antenna elements are positioned to overlap conductive portions, then high-frequency operation is improved, but isolation from low-frequency slot becomes challenging
Solution Approach 1:
The dielectric substrate acts as an intermediary between the high-frequency antenna elements and the low-frequency slot. This dielectric material provides electrical isolation and decoupling, allowing the antenna elements to overlap the conductive portions for enhanced high-frequency performance while preventing unwanted coupling with the low-frequency slot through the dielectric barrier.

AI summary
An antenna module includes: a dielectric substrate including upper and lower edges, opposing side edges, and interior and exterior faces, the substrate being placed in an aperture of a rim of a device such that the upper edge of the substrate is aligned with an upper edge of the rim, the opposing side edges of the substrate are adjacent opposing side edges of the aperture of the rim, and the lower edge of the substrate is adjacent a lower edge of the aperture of the rim; one or more antenna elements positioned adjacent the exterior face of the substrate and fed through apertures in the substrate; and one or more conductive portions shaped to define at least a part of a perimeter of a slot of a slot antenna fed separately to the antenna elements. The antenna elements wholly overlap the conductive portions and do not overlap the slot.
