Parallel U-Shaped Antenna Feeding System for Multi-Port Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna feeding systems require multiple phase shifters to achieve multi-port functionality, leading to increased size and complexity, making it difficult to achieve desired tilting angles and requiring individual control of each phase shifter.
Innovation Solution
A feeding system with parallel U-shaped patterns on substrates, where third patterns connect corresponding first patterns and fourth patterns connect corresponding second patterns, allowing for multi-port operation by adjusting the position of substrates to control the tilting angle, reducing the number of cables and simplifying control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple phase shifters are used to achieve multi-port functionality, then the number of ports increases, but the antenna size increases
Solution Approach 1:
The patent combines multiple phase shifter functions into a single integrated feeding system. Multiple U-shaped patterns (first, second, third, and fourth patterns) are configured on substrates to provide multiple ports while sharing common power supply paths, eliminating the need for separate phase shifters for each port and reducing overall antenna size.
Solution Approach 2:
The patent utilizes three-dimensional substrate stacking with first and second substrates positioned at different heights. The U-shaped patterns are distributed across multiple layers and connected through vertical vias, transforming a two-dimensional layout into a three-dimensional structure that achieves multi-port functionality without increasing the horizontal footprint of the antenna.
2Adaptability or versatility
If multiple phase shifters are used to achieve multi-port functionality, then the number of ports increases, but the device complexity increases
Solution Approach 1:
The feeding system provides universal power supply and phase control functionality across all ports through a single integrated design. The U-shaped patterns are configured to receive power from common power supply lines and control lines, allowing a single control mechanism to manage multiple ports simultaneously, thereby reducing control complexity while maintaining multi-port capability.
3Measurement precision
If individual control of each phase shifter is implemented, then phase adjustment precision improves, but the ease of operation deteriorates
Solution Approach 1:
The patent merges individual phase control functions into a unified control system. The U-shaped patterns are designed with shared control lines that can adjust the phase for multiple ports simultaneously through a single control signal, maintaining phase adjustment precision while significantly improving ease of operation by eliminating the need for individual control of each port.

AI summary
A feeding system is provided, and it supplies a power using conductive patterns divided into pattern groups, e.g. patterns having U shape. The feeding system includes a first substrate, first patterns disposed on the first substrate, second patterns disposed on the first substrate, and connected electrically in parallel to the first patterns, a second substrate spaced from the first substrate, at least one third pattern disposed on the second substrate, and configured to correspond to the first patterns and one or more fourth pattern disposed on the second substrate, and configured to correspond to the second patterns. Here, the third pattern connects electrically corresponding first patterns, and the fourth pattern connects electrically corresponding second patterns.
