Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antenna structures are used in high frequency bands, then the antenna structure is simple, but the signal is easily absorbed and lost leading to reduced communication quality
Solution Approach 1:
The feed line is designed with a coiled pattern instead of a straight configuration. This curved/coiled structure increases the electromagnetic coupling between the feed line and the patch antenna, thereby improving signal transmission efficiency and reducing signal loss in high frequency bands
Solution Approach 2:
The coiled feed line utilizes the vertical dimension by creating multiple loops that extend in the vertical direction. This three-dimensional configuration increases the interaction area between the feed line and patch antenna, enhancing electromagnetic coupling and improving communication reliability
2Power
If separate power amplifiers are implemented to secure antenna gain, then antenna gain is improved, but device complexity increases
Solution Approach 1:
The antenna feed system is integrated directly into the patch antenna structure through coiled feed lines. This integration eliminates the need for separate power amplifiers and external feeding mechanisms, thereby maintaining antenna gain while reducing overall device complexity
Solution Approach 2:
The coiled feed line structure itself generates the necessary electromagnetic coupling and signal concentration through its geometric configuration. The antenna system serves itself by using the coiled geometry to enhance gain without requiring additional active components like separate power amplifiers
