Research Objective
To enhance the impedance matching, gain and radiation behaviour of a 2.45 GHz biconical antenna using a frequency selective surface in Ansys HFSS.
System Architecture
The HFSS model can combine the biconical radiator, feed region, FSS superstrate or reflector layer, air spacing, radiation boundary and far-field setup for gain and pattern analysis.
Simulation Methodology
The base antenna is compared with the FSS-assisted design by sweeping FSS geometry, spacing and unit-cell parameters. The analysis focuses on resonance depth, bandwidth, gain and pattern stability.
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 resonance and bandwidth at 2.45 GHz
- gain and realized gain comparison
- 3D radiation pattern
- E-plane and H-plane radiation cuts
- surface current distribution on antenna and FSS
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.
- wideband FSS design
- low-profile biconical redesign
- specific absorption or near-field study
- IoT/WLAN integration case at 2.45 GHz
