Research Objective
To design and optimize an electrically small 90 MHz PCB loop antenna suitable for handheld RFID tag applications using CST Studio Suite.
System Architecture
The CST model can include PCB substrate, loop trace, matching gap, lumped port, tuning capacitor/inductor approximation, near-field monitor and radiation/far-field settings.
Simulation Methodology
Geometry and matching parameters are swept to improve resonance, impedance matching and magnetic near-field distribution while keeping the antenna electrically small and handheld-friendly.
Validation Scenarios
- base-case model setup and parameter verification
- main design or control case under rated operating conditions
- parametric change to prove robustness and sensitivity
- comparison with baseline or conventional method
- result discussion for thesis, paper and project-report writing
Expected Graphs and Result Discussion
A complete result section should include the main waveforms, model outputs, field plots or comparison tables needed for engineering thesis documentation. For this project, the important graph set includes:
- S11 and impedance response near 90 MHz
- magnetic near-field distribution
- current distribution on PCB loop
- radiation efficiency and pattern
- parameter sweep for loop geometry and matching
Thesis and Research Extension Ideas
The topic can be extended for journal-style novelty by adding optimization, robustness studies, comparative analysis, hardware-aware constraints or application-specific validation.
- RFID tag coupling distance study
- human-hand loading effect
- multi-turn loop optimization
- compact matching network design
