Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antennas face challenges in maintaining the surface condition of reflectors due to snow or ice accumulation, which affects radio wave concentration and antenna performance.
Innovation Solution
The antenna incorporates a heating layer with heating wires to melt snow or ice on the reflector, an insulating layer to direct heat upward, and additional layers for reinforcement and protection to ensure durability and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating layer is added to melt snow or ice on the reflector, then the surface condition of the reflector is maintained, but the device complexity increases
Solution Approach 1:
The heating layer is integrated within the reflector structure by nesting it between the reflective layer and the insulating layer. This nested configuration allows the heating function to be incorporated without significantly increasing the overall device complexity, as the heating elements are embedded within the existing reflector layers rather than adding external components.
Solution Approach 2:
The reflector is constructed as a composite structure with multiple functional layers including the reflective layer, heating layer, insulating layer, and reinforcement layer. Each layer serves a specific function, and their combination creates a multi-functional component that maintains the reflector surface while managing heat efficiently and providing structural support.
2Loss of energy
If an insulating layer is added to prevent heat transfer to the lower portion, then energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The insulating layer is nested between the heating layer and the reinforcement layer, creating a thermal barrier that prevents heat from reaching the lower portions of the reflector. This nested insulation approach efficiently reduces energy loss by confining heat to where it is needed (the reflective layer) without requiring separate external insulation structures.
3Strength
If reinforcement layers are added to increase strength, then durability is improved, but the device complexity increases
Solution Approach 1:
The reflector is designed as a composite structure where reinforcement layers are integrated with the functional layers (reflective, heating, and insulating layers). This composite approach provides structural strength and durability while maintaining a relatively simple overall structure, as the reinforcement is built into the layers rather than added as separate external supports.

AI summary
An antenna according to an embodiment comprises: a reflector, a transceiver disposed at one side of the reflector; and a support disposed at the other side of the reflector and serving to position the reflector apart from an installation position, wherein the reflector comprises: a reflective layer which reflects electromagnetic waves; a heating layer which is disposed on the lower surface of the reflective layer and generates heat for transfer to the top of the reflective layer; and a heat insulation layer which is disposed on the lower surface of the heating layer and serves to prevent heat generated in the heating layer from being transferred below the heating layer.
