Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna modules for mobile terminals often require slots or slits on the cover, which deteriorate the external design and functionality of the device.
Innovation Solution
An antenna module design that includes a ground plate, a metal plate spaced apart from the ground plate, and conductive members that are electrically coupled to form resonance frequencies without the need for slots, allowing for a multi-bandwidth operation while maintaining a sleek design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slots or slits are formed on the cover to implement antenna functions, then antenna operation is enabled, but external design is deteriorated
Solution Approach 1:
The patent merges the antenna function with the metal back cover by making the cover itself conductive and electrically connected to the ground plate. The metal plate serves dual purposes as both structural component and antenna element, eliminating the need for separate slots or slits in the cover.
Solution Approach 2:
The patent introduces connection members (such as conductive adhesives, metal sheets, or spring contacts) as intermediaries to establish electrical connection between the metal plate and ground plate. These connection members enable antenna functionality without requiring openings in the cover, thus preserving external design.
2Adaptability or versatility
If connection members are added to electrically couple the ground plate to the metal plate, then multi-bandwidth resonance is achieved, but device complexity increases
Solution Approach 1:
The connection members are designed to serve multiple functions: providing electrical connection for antenna operation, enabling multi-bandwidth resonance through strategic placement, and potentially serving as mechanical fasteners. This multi-functionality reduces overall device complexity despite adding components.
Solution Approach 2:
The patent uses multiple connection members positioned at different locations to create separate current paths that resonate at different frequencies. This segmentation allows multi-bandwidth operation while keeping each individual connection member simple in structure.

AI summary
Disclosed are an antenna module and a mobile terminal having the same. The antenna module includes a ground plate; a metal plate spaced apart from the ground plate by a distance such that a surface of the metal plate faces a surface of the ground plate; a first conductive member spaced apart from an edge of the ground plate by a distance, the first conductive member encompassing the edge; a feeding part formed on the ground plate; a second conductive member formed on the ground plate and coupled to the feeding part, wherein the second conductive member indirectly feeds the first conductive member and the metal plate; and a first connection member and a second connection member that couple the ground plate to the metal plate.
