Solution Overview

Problem

Consumer electronic devices require a large amount of space for multiple antennas due to their size being proportional to the wavelength of operation, need for isolation to prevent interference, and the complexity of installing and assembling these antennas.

Innovation Solution

The development of an antenna system that utilizes a single feeder to power multiple antenna modules, each capable of resonating at multiple frequencies, integrated into a continuous material structure with spreader structures to maintain optimal spacing and orientation of radiating elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate antennas are used to support multiple frequency bands, then frequency coverage is improved, but device volume and structural complexity increase

Engineering Contradiction:
Improvefrequency coverageVSAvoiddevice volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple antenna elements (driven element and parasitic elements) into a single integrated antenna structure that supports multiple frequency bands. The antenna module integrates multiple radiating elements that can operate at different frequencies (e.g., 2.4GHz, 5GHz, 6GHz WiFi bands) within one physical structure, eliminating the need for separate antennas for each frequency band.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The antenna module is designed to perform multiple functions simultaneously - it can operate across multiple frequency bands (2.4GHz, 5GHz, 6GHz) and support different wireless standards (WiFi, Bluetooth, etc.) using the same physical structure. The parasitic elements can be selectively activated or deactivated to provide multi-band operation from a single antenna module.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate antennas are used to support multiple frequency bands, then frequency coverage is improved, but structural complexity increases

Engineering Contradiction:
Improvefrequency coverageVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple antenna elements into a single integrated module where driven and parasitic elements are structurally combined. This integration reduces the number of separate components, mounting structures, and assembly steps required compared to using multiple discrete antennas.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The antenna module is segmented into functional elements (driven element and parasitic elements) that can be independently designed and optimized for different frequency responses, yet are structurally integrated. This segmentation allows for complex multi-band functionality while maintaining a unified structural approach.

Inventive Principle:

Solution Approach 1:

The patent combines multiple antenna elements into a single module that is pre-assembled and optimized for proper spacing and orientation. This integrated module eliminates the need for complex field installation and alignment of multiple separate antennas, while maintaining signal quality through the designed separation between driven and parasitic elements.

Inventive Principle:
Principle #5Merging (Combining)
