Dual-Band Antenna Module Layout for Compact Isolation

The patent combines multiple slits for different frequency bands into a single integrated slit structure on the ground electrode. Instead of forming separate slits for each frequency band, the invention creates one unified slit that serves multiple frequency isolation functions, thereby reducing the total occupied area while maintaining isolation performance across multiple bands.

The single slit structure is designed to perform multiple functions by providing isolation for signals of different frequency bands simultaneously. The slit configuration enables it to block or reduce coupling between antennas across multiple frequency ranges, making one structural element serve universal isolation purposes rather than requiring dedicated slits for each band.

By merging multiple frequency-specific slits into a single integrated slit structure, the patent reduces the number of separate features on the ground electrode. This consolidation frees up space and reduces geometric constraints, allowing for more flexible arrangement of electronic components such as antennas, capacitors, and other elements that need to be mounted on or near the ground electrode.

The single slit structure can be designed with internal segmentation or sub-features that provide frequency-specific isolation functions while maintaining an integrated external form. This allows the slit to be divided into functional zones for different frequencies without requiring separate physical slits, thereby preserving component arrangement flexibility.

The patent applies local quality by creating variations in the single slit structure at different locations or sections to optimize isolation for specific frequency bands. The slit may have different widths, depths, shapes, or additional features at different positions along its length, allowing each local region to be tuned for optimal performance at particular frequencies while maintaining the overall compact structure.

The invention utilizes parameter changes by varying geometric parameters of the slit (such as width, length, depth, curvature, or cross-sectional shape) to achieve different isolation characteristics across frequency bands. By adjusting these parameters in different regions of the single slit, the structure can provide effective isolation for multiple frequencies despite the reduced occupied area compared to separate slits.
