Solution Overview

Problem

Current phased array antennas are large, costly, and unsuitable for consumer terminal products due to their size and high cost, failing to meet the requirements for a high-throughput MIMO system with a simple, small-volume, and low-cost design that allows for adjustable space electromagnetic field direction.

Innovation Solution

An antenna apparatus with a simple structure, small volume, and low costs, featuring a phase adjustment area connected between two radiation areas to adjust the phase of the signal, changing the direction of the space electromagnetic field, and including an antenna debug circuit to adjust phase, amplitude, or frequency, facilitating spatial multi-color coverage and increased throughput.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a phased array antenna is used to adjust the direction of space electromagnetic field, then the beam scanning capability is improved, but the device size and cost increase significantly

Engineering Contradiction:
Improvebeam scanning capabilityVSAvoiddevice size and cost
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The antenna is divided into multiple radiation elements (first radiation section and second radiation section) that are spatially separated and connected through a phase adjustment area. Each radiation element can be independently controlled to radiate electromagnetic signals in different directions, achieving beam scanning without requiring a complex phased array structure. This segmentation allows the antenna to maintain adaptability while reducing overall device complexity and size.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A phase adjustment area is introduced as an intermediary component between the feeding point and the radiation elements. This phase adjustment area modifies the phase of the signal fed to each radiation element, enabling directional control of the electromagnetic field. By using this intermediate phase adjustment mechanism, the patent achieves beam scanning capability without the need for complex phased array control systems, thus reducing device complexity and cost.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the antenna structure is simplified to reduce cost and size, then the manufacturing cost and device volume are reduced, but the capability to adjust space electromagnetic field direction is lost

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The phase adjustment area is strategically positioned and designed with specific local properties to perform phase modification. By concentrating the phase adjustment function in a dedicated local region rather than distributing it throughout the entire antenna structure, the patent achieves directional control capability while maintaining overall structural simplicity. This local quality approach allows the antenna to remain simple and cost-effective while retaining the essential adaptability for electromagnetic field direction adjustment.

AI summary

An antenna apparatus includes a first radiation area, a phase adjustment area and a second radiation area. The first radiation area is disposed opposite to the second radiation area. The first radiation area is connected to one end of the phase adjustment area. The other end of the phase adjustment area is connected to the second radiation area. The first radiation area includes a feeding point of the antenna apparatus. The second radiation area includes a ground point of the antenna apparatus. The phase adjustment area is used to adjust a phase of a signal fed by the feeding point, to change a direction of a space electromagnetic field formed by an electromagnetic signal radiated by each of the first radiation area and the second radiation area.
