Wearable Tri-Band Antenna Design in HFSS: Research Workflow
Wearable antennas combine electromagnetic design with mechanical flexibility and user proximity. A tri-band structure can target WLAN, sub-6 GHz or sensing applications while testing bending and on-body performance.
Geometry and substrate
Flexible low-loss substrates, compact radiators and partial or defected grounds are common starting points. Each resonance should be traceable to a geometry feature.
Bending and on-body evaluation
The design should be tested at multiple bending radii and near tissue-equivalent models. Resonance shift, efficiency and pattern distortion provide useful robustness metrics.
Safety and performance
Depending on application, SAR, gain, efficiency, bandwidth, current distribution and radiation pattern should be included.
Novelty options
Independent resonance control, compact decoupling, textile/flexible integration, reconfigurability or improved SAR isolation can create a stronger research contribution.

Frequently asked questions
Yes. Flexible structures can be modeled on curved surfaces or with parameterized bend radii.
For on-body applications it is often an important safety metric; whether it is mandatory depends on the research goal and intended use.
