Antenna Module Shield Layout for Connector Leakage Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In antenna-integrated modules, radio-frequency components are affected by leakage noise from connectors, which degrades antenna characteristics.
Innovation Solution
An antenna module with a first shield structure that covers at least part of the connector and is positioned between the radio-frequency circuit component and the connector, featuring a side plate that surrounds the connector and has an opening for a cable, thereby reducing noise influence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common frame element covers both radio-frequency components and connector, then structural simplicity is improved, but noise shielding performance deteriorates
Solution Approach 1:
The patent divides the shielding structure into two separate components: a first shield structure covering the radio-frequency circuit component and a second shield structure covering the connector. This segmentation allows each shield to be optimized independently for its specific function, preventing noise from the connector from affecting the radio-frequency components while maintaining structural organization.
Solution Approach 2:
The patent introduces a partition wall as an intermediary structure between the first shield structure and the second shield structure. This partition wall physically separates the radio-frequency component region from the connector region, creating an additional noise barrier that prevents electromagnetic interference from the connector from reaching the sensitive radio-frequency circuits.
2Object-affected harmful factors
If the shield structure completely encloses the connector, then noise shielding is improved, but cable accessibility deteriorates
Solution Approach 1:
The second shield structure, which covers the connector, is designed with a local opening that specifically accommodates the cable. This allows the shield to provide comprehensive noise protection for the connector while maintaining localized accessibility for cable connection and disconnection operations, ensuring that the shielding function does not compromise operational convenience.

AI summary
A radio-frequency integrated circuit processes a radio-frequency signal to be transmitted or received by an antenna. The radio-frequency integrated circuit is implemented on a first substrate. The first substrate is implemented on a second substrate. A connector for connection with a cable through which a modulation signal is transferred to the radio-frequency integrated circuit is implemented on the second substrate. A first shield structure covers the connector. An antenna module in which noise due to the connector is less likely to influence antenna characteristics is provided.
