Research Objective
To design a wearable tri-band antenna operating near 2.4 GHz, 3.8 GHz and 5 GHz using Rogers RO5880 substrate in Ansys HFSS 2024.
System Architecture
The antenna can be configured using compact radiating slots or stubs, Rogers RO5880 substrate, partial ground or defected ground, coaxial/lumped feed and radiation boundary setup.
Simulation Methodology
The design is tuned to obtain three resonant bands while monitoring impedance bandwidth, gain, pattern stability, efficiency and wearable suitability under bending or body-proximity cases.
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 response at 2.4, 3.8 and 5 GHz
- radiation pattern for each band
- gain and efficiency comparison
- surface current at each resonance
- bending or body-proximity sensitivity
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.
- SAR analysis near human tissue
- textile substrate comparison
- MIMO wearable version
- flexible and conformal bending optimization
