Solution Approach 1:

The patent merges the radiator and resonators onto a single substrate, eliminating the need for separate FPCBs and pillars. The radiator is disposed on a first substrate while resonators are disposed on a second substrate that is integrated with the first substrate, consolidating multiple antenna components into one unified structure and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The substrate serves multiple functions by simultaneously supporting both the radiator and resonators. The first substrate acts as both the mounting platform for the radiator and provides structural support for the integrated second substrate containing resonators, reducing the need for additional support structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 1:

The patent segments the antenna system into distinct functional areas: the radiator is disposed on a first substrate while resonators are disposed on a second substrate. This spatial segmentation prevents signal interference between the radiator and resonators while maintaining efficient use of overall space through vertical integration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from planar arrangement to three-dimensional stacking by disposing the resonators on a second substrate that is integrated with the first substrate. This vertical arrangement in another dimension allows both the radiator and resonators to coexist without spatial overlap, preventing signal interference while maximizing spatial utilization.
