Solution Overview

Problem

Existing antenna designs for terminals require a large space to accommodate both 4G and 5G frequency bands, which hinders the arrangement of other electronic components due to their size.

Innovation Solution

An integrated antenna design with a grounding area, a first radiator for the 5G frequency band, and a second radiator for the 4G frequency band, connected via a slot-coupling, allowing both bands to be supported simultaneously while minimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate antennas are provided for 4G and 5G frequency bands, then both frequency bands can be supported, but the terminal occupies more internal space affecting arrangement of other electronic components

Engineering Contradiction:

Improvefrequency band supportVSAvoidantenna space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines two separate antennas for 4G and 5G frequency bands into a single integrated antenna structure. The antenna includes a grounding area, a first radiator for 5G frequency band, and a second radiator for 4G frequency band, all connected through a feeding point. This merging approach maintains support for both frequency bands while reducing the total space occupied in the terminal.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated antenna is designed to perform multiple functions by supporting both 4G and 5G frequency bands simultaneously. The single antenna structure with multiple radiators enables the terminal to communicate across different frequency bands without requiring separate dedicated antennas for each band, thus achieving multi-functionality with reduced component count.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two separate antennas are provided for 4G and 5G frequency bands, then both frequency bands can be supported, but the arrangement of other electronic components is affected

Engineering Contradiction:

Improvefrequency band supportVSAvoidcomponent arrangement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By merging two separate antennas into one integrated antenna structure, the patent reduces the number of components that need to be arranged in the terminal. The integrated design with shared grounding area and feeding point simplifies the overall antenna system, making it easier to arrange other electronic components without interference from multiple separate antenna structures.
