Problem

Current electronic devices are limited by the number of antennas, which cannot meet the higher demands for communication functionality, particularly with the increasing need for multiple antennas to ensure effective communication in advanced communication technologies.

Innovation Solution

An antenna assembly with a metal main body and multiple radiating elements connected through metal connecting parts, integrated with a circuit board featuring multiple feeds, matching circuits, and frequency band switching modules to form an 8×8 MIMO antenna system, supporting dual-frequency bands and enabling the transmission of 5G signals alongside 4G LTE signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple antennas are equipped to ensure good communication, then communication reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidantenna system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple radiating elements (first through eighth radiating elements) into a single integrated antenna assembly structure. These radiating elements are arranged on a common support structure with shared connecting parts, merging what would otherwise be separate antenna components into one unified assembly, thereby achieving multiple antenna functions while controlling overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The antenna assembly is designed to support multiple communication functions simultaneously through its multiple radiating elements. The structure can handle different frequency bands and communication protocols (4G LTE, 5G, Wi-Fi, Bluetooth) using the same physical assembly, making the antenna system universal and multi-functional rather than requiring separate dedicated antennas for each function

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

2Adaptability or versatility

If 8×8 MIMO antenna system is implemented, then communication capability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvecommunication capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The antenna assembly is segmented into modular components including multiple radiating elements, connecting parts, and a support structure. Each radiating element can be independently positioned and connected, allowing for modular assembly and manufacturing. The connecting parts serve as standardized interfaces that simplify the assembly process for creating the 8×8 MIMO configuration

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The antenna assembly employs a nested structure where radiating elements are arranged in layers or groups on the support structure. The first and second radiating elements are connected to the first connecting part, while third and fourth radiating elements connect to the second connecting part, creating a nested organizational pattern that simplifies manufacturing by grouping related components together

Inventive Principle:
Principle #7Nested doll (Nesting)
