Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for electromagnetic waves, particularly in the millimeter-wave frequency range, face challenges in alignment and space efficiency, leading to increased time and cost for assembly and potential signal loss due to improper coupling between antenna and waveguide members.
Innovation Solution
The use of a waveguide member with a polymer fiber core, a dielectric layer of lower permittivity, a metallic shield, and a plastic outer layer, featuring a recess at one end to partially receive the antenna member, ensuring precise alignment and efficient coupling, with optional complementary recess and antenna designs for enhanced assembly and signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional waveguide members are brought close to or into direct contact with antenna members for coupling electromagnetic waves, then coupling efficiency can be achieved, but alignment is time and cost consuming and the arrangement requires large volume
Solution Approach 1:
The recess is pre-formed in the waveguide member at a predetermined position, allowing the antenna member to be inserted and automatically aligned without time-consuming adjustment procedures. The recess acts as a pre-prepared receptacle that guides the antenna into the correct position, eliminating the need for manual alignment operations.
Solution Approach 2:
The antenna member is inserted into and nested within the recess of the waveguide member, creating a compact integrated structure. This nesting arrangement reduces the overall volume required for the antenna-waveguide assembly while ensuring proper coupling between the two components through their nested geometric relationship.

This nesting arrangement reduces the overall volume required for the antenna-waveguide assembly while ensuring proper coupling between the two components through their nested geometric relationship.
Solution Approach 2:
The recess extends into the waveguide member along its longitudinal axis, utilizing the internal dimensional space of the waveguide rather than requiring additional external space. This dimensional utilization allows the antenna to be coupled to the waveguide without increasing the overall footprint or volume of the assembly.
3Ease of operation
If the waveguide member is provided with a recess to receive the antenna member, then alignment is simplified and coupling efficiency is improved, but the waveguide structure becomes more complex
Solution Approach 1:
The waveguide member is segmented into distinct functional layers including the core made from polymer fibres, a dielectric layer surrounding the core, a metallic shielding layer, and an outer jacket. The recess is formed within this segmented structure, allowing the complexity to be organized into manageable functional segments rather than a monolithic complex structure.
Solution Approach 2:
The waveguide member employs composite material construction with a core made from polymer fibres surrounded by a dielectric layer, metallic shielding, and plastic outer jacket. This composite structure accommodates the recess while maintaining the integrity of each material layer, distributing the structural complexity across multiple material systems with complementary properties.
