Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the first antenna module and second antenna module are mounted close to each other in the accommodation cavity, then the device size is reduced, but the isolation between the two antenna modules deteriorates
Solution Approach 1:
A filtering module is introduced as an intermediary component positioned between the first antenna module and second antenna module. This filtering module includes filtering elements that selectively block electromagnetic waves while allowing other functions to pass through, thereby reducing interference between the two antenna modules without increasing the overall device volume
Solution Approach 2:
The filtering module is strategically positioned only in the region where electromagnetic wave interference occurs between the two antenna modules, rather than throughout the entire device. This localized approach provides the necessary isolation while minimizing the impact on device size and maintaining spatial efficiency
2Object-affected harmful factors
If a filtering module is added between the first antenna module and second antenna module, then the isolation between the two modules is improved, but the device complexity increases
Solution Approach 1:
The filtering module utilizes thin film structures as filtering elements, which provide effective electromagnetic wave blocking capabilities while occupying minimal space. These thin film filtering elements can be integrated into the existing device structure with minimal additional complexity
Solution Approach 2:
The filtering module employs composite material structures that combine different materials with complementary properties to achieve effective electromagnetic wave filtering. This allows for optimized performance while maintaining a compact and integrated design that does not significantly increase device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The filtering module effectively reduces electromagnetic wave interference, improving signal receiving sensitivity and transmission quality, and extending the service life of the antenna assembly components.
Implementation Method 1
the filtering module can reflect at least a part of output electromagnetic waves, thereby reducing a risk that output electromagnetic waves generated by the first antenna module are transferred to the second antenna module
Implementation Method 2
the filtering module can absorb and consume energy of output electromagnetic waves, to weaken strength of output electromagnetic waves near the second antenna module

AI summary
This application relates to an antenna assembly and a communication device. The antenna assembly includes an enclosure, a first antenna module, a second antenna module, and a filtering module. The first antenna module and the second antenna module are both mounted in an accommodation cavity of the enclosure. The filtering module is located along a distribution direction of the first antenna module and the second antenna module and between the first antenna module and the second antenna module adjacent to each other. The filtering module can reflect at least a part of output electromagnetic waves, thereby reducing a risk that output electromagnetic waves generated by the first antenna module are transferred to the second antenna module; and/or the filtering module can absorb and consume energy of the output electromagnetic waves, to weaken strength of output electromagnetic waves near the second antenna module. This increases isolation between the first antenna module and the second antenna module, enhances signal receiving sensitivity of the antenna assembly and the communication device, and improves signal transmission quality and signal transmission stability of the antenna assembly and the communication device.
