Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna array designs face challenges in miniaturization and freedom of wiring due to direct coupling of signal transmission lines, leading to significant area occupation and undesired interference.
Innovation Solution
The antenna array features a flexible design with adjustable signal-feeding points, where each antenna unit has a default and an actual feeding point, allowing for flexible signal transmission line arrangements and reduced trace area occupation, enabling varied coupling configurations among antenna units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal transmission lines are directly coupled to feeding points in conventional antenna arrays, then signal transmission is achieved, but the wiring freedom is confined and significant area is occupied causing undesired interference
Solution Approach 1:
The patent segments the signal transmission path by introducing intermediate coupling points between the feeding points and antenna units. Instead of direct coupling, the signal transmission lines are divided into multiple segments that connect through intermediate structures, thereby increasing wiring flexibility while reducing the occupied area and interference.
2Object-affected harmful factors
If signal transmission lines are directly coupled to feeding points, then signal transmission is achieved, but undesired interference is caused and miniaturization is difficult
Solution Approach 1:
The patent introduces intermediate coupling points as mediators between the feeding points and antenna units. These intermediate points serve as buffer zones that reduce direct coupling between signal transmission lines and antenna elements, thereby minimizing undesired interference while allowing for more compact trace routing that reduces the overall occupied space.
3Adaptability or versatility
If conventional series-fed or parallel-fed antenna architectures are used, then antenna array functionality is achieved, but wiring design freedom is confined
Solution Approach 1:
The patent implements a dynamic wiring architecture where the signal transmission lines can be selectively connected to different antenna units through controllable coupling points. This dynamic configuration allows the antenna array to adapt its wiring topology based on operational requirements, significantly enhancing wiring design freedom while maintaining manageable structural complexity through systematic connection patterns.

AI summary
An antenna array includes an external input signal feeding point for receiving or transmitting therefrom an input signal or an output signal; signal transmission lines; and antenna units including a starting antenna unit coupled to the external input signal feeding point via a starting feeding point thereof, and being interconnected via the plurality of signal transmission lines. The input/output signal delivered from the external input signal feeding point enters the starting antenna unit from the starting feeding point and is further transmitted to the other antenna units through the signal transmission lines. Each of the antenna units is defined with a default feeding point at a position corresponding to a position of the starting feeding point in the starting antenna unit. One of the signal transmission lines has an end directly coupled to one of the antenna units at an actual feeding point different from the default feeding point for receiving therefrom the input signal.
