Phased Array Antenna Relay Adapter Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing phased array antennas require high mounting accuracy for antenna elements and blocks, leading to increased costs and structural limitations due to the need for equal pitch arrangements, which restricts the flexibility in designing the antenna frame and block configurations.
Innovation Solution
The phased array antenna design incorporates a relay adapter that allows for independent pitch arrangements of antenna elements and blocks, using a front plate with a coolant flow path for heat dissipation and a bus board with a detachable capacitor bank, enabling relaxed mounting accuracy and flexible block configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high mounting accuracy is required for antenna elements and blocks, then the antenna performance is improved, but the manufacturing cost increases and productivity decreases
Solution Approach 1:
The antenna system is divided into multiple independent blocks, each containing multiple slices. This segmentation allows each block to be manufactured and assembled separately with relaxed precision requirements, then combined to form the complete antenna array, thereby improving productivity while maintaining overall antenna performance.
Solution Approach 2:
A relay adapter is introduced as an intermediary component between the slice and the block structure. This relay adapter provides mechanical tolerance compensation and electrical connection, allowing the slice pitch to differ from the block pitch without affecting performance, thus reducing mounting accuracy requirements and increasing manufacturing efficiency.
2Reliability
If equal pitch arrangement is required for all antenna elements, then the antenna pattern is optimized, but the structural flexibility is reduced and device complexity increases
Solution Approach 1:
The patent allows different pitch arrangements within slices and between blocks, breaking the traditional symmetric equal-pitch constraint. The relay adapter enables asymmetric positioning while maintaining electrical continuity, providing structural flexibility for optimized antenna patterns without requiring uniform pitch throughout the entire array.
Solution Approach 2:
The system allows dynamic configuration where the pitch between slices within a block can differ from the pitch between blocks. This dynamic pitch arrangement capability enables optimization of antenna radiation patterns for different application scenarios while maintaining structural integrity through the relay adapter mechanism.
3Manufacturing precision
If strict structural limitations are imposed on antenna frame and block, then the mounting accuracy is maintained, but the ease of manufacture is reduced and device complexity increases
Solution Approach 1:
The antenna system is divided into modular blocks that can be manufactured independently using standard manufacturing processes. Each block contains multiple slices that are also independently manufacturable, allowing for simplified production without requiring complex integrated structures, thereby improving ease of manufacture while maintaining mounting accuracy through modular assembly.
Solution Approach 2:
The relay adapter serves as a standardized intermediary component that simplifies the manufacturing process by providing a universal interface between slices and blocks. This standardized component allows for easier manufacturing and assembly compared to custom-fitted connections, reducing the need for strict structural limitations while maintaining mounting accuracy.
