Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional triplate feed-type planar antennas experience increased heat loss and degradation of characteristics when handling high-power transmission waves due to low heat-resistant materials and inefficient heat radiation, leading to unstable performance and reliability.
Innovation Solution
The triplate feed line is optimized by setting the width and length of the section between the waveguide/triplate-line converter and the branch point to minimize loss and impedance mismatch, ensuring that the temperature and heat generated remain within safe limits, allowing for precise power distribution to patch antennas without degrading characteristics.

Engineering Contradiction Analysis
1Power
If the feed line handles high-power transmission waves, then the power transmission capability is improved, but heat loss increases and characteristics degrade due to low heat-resistant materials
Solution Approach 1:
The patent optimizes the width and length parameters of the feed line section between the waveguide/triplate-line converter and the branch point. By carefully selecting these dimensional parameters, the feed line achieves minimal loss and impedance mismatch, enabling high-power transmission while controlling heat generation within safe limits.

If the feed line handles high-power transmission waves, then the power transmission capability is improved, but the temperature and heat generated exceed safe limits causing material degradation
Solution Approach 1:
The patent specifies particular width and length parameters for the feed line section to control the temperature and heat generation. These parameter optimizations ensure that even under high-power transmission conditions, the temperature and heat remain within safe limits that prevent degradation of the foam sheet and other materials.
3Loss of energy
If the width and length of the feed line section are optimized, then the loss and impedance mismatch are minimized, but the device complexity increases due to precise dimensional requirements
Solution Approach 1:
The patent determines specific width and length parameters for the feed line that optimize performance while avoiding excessive complexity. By carefully selecting these parameters, the invention achieves minimal loss and impedance mismatch without requiring overly complex structures or manufacturing processes.

AI summary
A feed line in the form of a trip late line that runs from a waveguide/triplate-line converter coupled to a radio to a plurality of patch antennas in a cluster pattern. The width and length of a section of said feed line between the waveguide/triplate-line converter and the branch point nearest thereto are set such that the impedance of said section directly matches the parallel combination of the impedances of branches beyond said branch point and the loss in said section is kept to or below a predetermined upper limit.
