Antenna Array Micro-Strip Design for Directional Signal Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna arrays require a ground plate to enhance directionality, increasing cost and weight, and existing designs do not efficiently concentrate radio signal energy in a predetermined direction.
Innovation Solution
An antenna array design featuring a base plate with radiator sets and micro-strips, where the radiator sets are coupled one-by-one to micro-strips, and a metal layer on the reverse side of the base plate blocks signal emission to concentrate energy in a specific direction, with the radiator and micro-strip impedances being complex conjugate matched.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If a ground plate is used to enhance directionality in conventional antenna arrays, then the directionality is improved, but the weight and cost increase
Solution Approach 1:
The invention extracts and eliminates the ground plate from the conventional antenna array structure. By using a base plate without a ground plate, the design achieves directionality enhancement through alternative means (micro-strip configurations and radiator arrangements) while removing the unnecessary weight and cost associated with the ground plate.
Solution Approach 2:
The invention changes the structural parameters of the antenna array by replacing the ground plate with a base plate configuration that uses micro-strips and radiators arranged in specific patterns. This parameter change maintains or improves directionality while reducing weight and cost.
2Volume of stationary object
If a ground plate is used to enhance directionality in conventional antenna arrays, then the directionality is improved, but the cost increases
Solution Approach 1:
The invention extracts and eliminates the ground plate from the conventional antenna array structure. By using a base plate without a ground plate, the design achieves directionality enhancement through alternative means (micro-strip configurations and radiator arrangements) while removing the unnecessary weight and cost associated with the ground plate.
Solution Approach 2:
The invention replaces the expensive ground plate with a more cost-effective base plate configuration using standard micro-strip and radiator components that can be manufactured more economically while achieving the same directionality function.
3Device complexity
If conventional antenna designs are used, then the structure is simple, but the energy concentration in a predetermined direction is insufficient
Solution Approach 1:
The invention segments the antenna structure into multiple radiators (first radiator, second radiator, third radiator, fourth radiator) arranged in specific configurations on the base plate. This segmentation allows each radiator to contribute to the overall energy concentration in the predetermined direction, achieving better performance than a simple single-antenna design.
Solution Approach 2:
The invention enhances energy concentration by utilizing spatial arrangements in multiple dimensions - radiators are positioned at different locations and orientations on the base plate, creating a three-dimensional radiation pattern that concentrates energy in the desired direction while maintaining reasonable structural complexity.
