Solution Overview

Problem

The compact design of modern wireless devices limits available space for antenna systems, and integrating multiple antennas for multi-band communication poses challenges, with traditional tuner codeword construction being manual and inefficient, leading to performance trade-offs across different frequency bands.

Innovation Solution

An adaptive tuner selection algorithm optimizes the construction of a tuner codeword database by considering user-defined weightings and environmental factors, enhancing performance on preferred bands while minimizing degradation in others, using a predetermined weighting and filtering mechanism to select optimal tuner codewords.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single tuner codeword is used to cover a limited frequency range, then device complexity is reduced, but communication performance across multiple frequency bands deteriorates

Engineering Contradiction:
Improvetuner codeword configurationVSAvoidcommunication performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the frequency spectrum into multiple bands (e.g., Band 1, Band 2, Band 3) and assigns different tuner codewords to different bands. The antenna tuner controller selectively applies appropriate codewords based on the operating frequency band, allowing optimized performance for each band rather than using a single compromise codeword for all bands.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects and switches between different tuner codewords based on real-time operating conditions, frequency band, and signal characteristics. The antenna tuner controller continuously monitors performance and adjusts the tuner codeword selection to maintain optimal communication performance across varying conditions.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple antennas are integrated for multi-band communication, then frequency band coverage is expanded, but available internal space is reduced

Engineering Contradiction:
Improvefrequency band coverageVSAvoidinternal space
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent implements a multi-functional antenna system where a single antenna structure serves multiple frequency bands through electronic tuning. The antenna tuner controller switches between different tuner codewords to enable the same antenna to operate across Band 1, Band 2, Band 3 and other frequency ranges, eliminating the need for separate dedicated antennas for each band.

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

Solution Approach 2:

The system changes the electrical parameters of the antenna by applying different tuner codewords that adjust impedance matching and resonant frequencies. This allows a single physical antenna structure to adapt its electrical characteristics to match different frequency bands, achieving multi-band coverage without adding physical antenna elements.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If manual tuner codeword construction is used, then construction precision can be controlled, but construction time and efficiency are reduced

Engineering Contradiction:
Improvetuner codeword constructionVSAvoiddatabase construction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements an automated system where the antenna tuner controller performs self-testing and self-optimization by automatically measuring signal quality metrics (RSRP, SINR, VSWR) and selecting optimal tuner codewords without manual intervention. The system builds and updates the tuner codeword database autonomously through real-world operation and performance monitoring.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where the antenna tuner controller continuously monitors communication performance metrics and uses this feedback to automatically adjust tuner codeword selection and update the database. The measured performance data feeds back into the selection algorithm, enabling continuous optimization without manual reconfiguration.

Inventive Principle:
Principle #23Feedback
