Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antennas face performance deterioration due to electromagnetic responses caused by microwave signals irradiating onto the driving structure, which affects the phase adjustment and radiation efficiency.
Innovation Solution
The antenna design incorporates a phase adjusting structure, a driving structure, a radiating structure, and an isolation layer, where the isolation layer with a first opening blocks the driving structure, preventing electromagnetic interference and ensuring efficient phase adjustment and radiation of microwave signals.

1Volume of moving object
If the driving structure is exposed to microwave signals, then the antenna can be miniaturized and integrated, but the electromagnetic response deteriorates antenna performance
Solution Approach 1:
The antenna structure is segmented into distinct functional layers: a radiating structure layer, a phase adjusting structure layer, and a driving structure layer. The isolation layer with its first opening further segments the microwave signal path, allowing only specific regions to interact with microwave signals while isolating the driving structure from direct exposure.
Solution Approach 2:
The isolation layer acts as an intermediary between the radiating structure and the driving structure. It selectively transmits microwave signals to the phase adjusting structure while blocking direct exposure of the driving structure to microwave signals, thus mediating the interaction between electromagnetic fields and electrical components.
2Reliability
If the driving structure is isolated from microwave signals, then antenna performance is maintained, but device complexity increases
Solution Approach 1:
The isolation layer serves multiple functions simultaneously: it provides electromagnetic isolation to protect the driving structure, supports the phase adjusting structure, and its first opening enables selective signal transmission. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The isolation layer is merged with the phase adjusting structure support function, and the first opening is integrated into the isolation layer itself rather than being a separate component. This merging approach simplifies the overall structure while maintaining the required isolation functionality.
3Productivity
If the first opening overlaps with the radiating structure, then microwave signal transmission is enabled, but electromagnetic interference may occur
Solution Approach 1:
The isolation layer exhibits local quality variation through its first opening: regions with the opening allow microwave signal transmission while regions without the opening provide electromagnetic isolation. This spatially selective property enables different functional zones within the same layer.
Solution Approach 2:
The first opening, which could potentially allow unwanted electromagnetic interference, is strategically positioned and sized to enable necessary signal transmission while the surrounding isolated regions of the isolation layer compensate by blocking interference paths, converting a potential harm into a beneficial signal channel.

This configuration effectively prevents electromagnetic responses that deteriorate antenna performance, enhancing phase shifting efficiency and radiation transmission while maintaining miniaturization and integration.
Implementation Method 1
the driving structure is electrically connected to the phase adjusting structure and is configured to provide a driving voltage to the phase adjusting structure for adjusting a phase of a received microwave signal
Implementation Method 2
the radiating structure is configured to transmit the received microwave signal to the phase adjusting structure and radiate the microwave signal adjusted by the phase adjusting structure
