Solution Overview

Problem

The existing method of installing a separate service band separator/combiner for mobile communication base stations is costly in terms of materials and manufacturing, and poses challenges related to waterproofing and aesthetics due to external connections.

Innovation Solution

An antenna device with a reflector having radiating elements and an integrated cylindrical radome that houses the service band separator/combiner, reducing external connections and manufacturing costs while enhancing waterproofing and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate service band separator/combiner is installed at the front end of the antenna device, then service band separation and combination functions are achieved, but material cost and manufacturing cost increase

Engineering Contradiction:

Improveservice band separation functionVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The service band separator/combiner is integrated into the antenna device housing, merging two separate devices into one. This eliminates the need for a separate service band separator/combiner unit, reducing material costs and manufacturing complexity while maintaining the service band separation and combination functions

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The antenna device housing is designed to serve multiple functions: it provides structural protection for the radiating elements, serves as the housing for the service band separator/combiner, and enables service band separation and combination operations. This multi-functionality reduces the need for additional separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a service band separator/combiner is installed with external cable connections, then service band processing is enabled, but waterproofing problems and aesthetic issues arise

Engineering Contradiction:

Improveservice band processing capabilityVSAvoidwaterproofing issue

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The service band separator/combiner is merged with the antenna device housing, eliminating external cable connections. All components are housed within a single sealed unit, which prevents waterproofing issues that would arise from external connections while maintaining full service band processing capability

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If a service band separator/combiner is installed with external cable connections, then service band processing is enabled, but installation cost and aesthetic appearance deteriorate

Engineering Contradiction:

Improveservice band processing functionVSAvoidaesthetic appearance

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The service band separator/combiner is combined with the antenna device housing into a single integrated unit. This eliminates external cables and separate mounting hardware, resulting in a clean, streamlined appearance while maintaining the service band processing function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated housing serves as both the structural enclosure for the radiating elements and the service band separator/combiner, creating a unified aesthetic design that eliminates the need for separate mounting structures and external connections

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present disclosure relates to an antenna device for a mobile communication system, including a reflection plate, a service band separator/coupler and a radome. The reflection plate is configured in a plate shape, multiple radiation elements being mounted on one surface of the reflection plate so as to transmit/receive radio signals. The service band separator/coupler is installed on the other surface of the reflection plate so as to separate/couple the service band of the corresponding antenna device. The radome is configured in the shape of an integrated barrel that surrounds the reflection plate and the service band separator/coupler as a whole.
