Summary
This study presents a reconfigurable textile antenna for wearable devices, achieving a wide impedance bandwidth and flexible polarization control using snap buttons. The design is validated for real-world conditions like body proximity and bending.
Area of Science:
- Electrical Engineering
- Materials Science
Background:
- Wearable applications require compact and versatile antennas.
- Existing textile antennas often lack reconfigurability and sufficient bandwidth.
Purpose of the Study:
- To design a bandwidth-enhanced, polarization-reconfigurable antenna for wearable technology.
- To enable flexible frequency coverage and polarization switching.
Main Methods:
- A textile half-mode substrate-integrated cavity (HMSIC) antenna was modified with a slot to create dual resonances.
- Snap buttons were integrated to reconfigure the antenna's impedance bandwidth and polarization state.
Main Results:
- The fabricated antenna achieved a reconfigurable -10 dB impedance bandwidth of 2.29–2.63 GHz (13.9% fractional bandwidth).
- Linear and circular polarization were demonstrated at 2.42 GHz by switching snap button states.
- Performance was validated under human body proximity and bending conditions.
Conclusions:
- The proposed textile HMSIC antenna offers a flexible solution for wearable applications.
- The design successfully achieves bandwidth enhancement and polarization reconfigurability.
