In this work, a unique antenna intended for Wireless Body Area Network (WBAN) applications is presented. To increase its bandwidth and handle several frequency bands, the suggested antenna makes use of slotting and multi-resonant radiators with capacitive coupling. The Characteristic Mode Analysis (CMA) technique achieves the antenna’s high-Q resonance bandwidth while maintaining other spectral properties. The 2.4–2.6 GHz impedance bandwidth WLAN bands are serviced by the designed antenna, which has a directed radiation pattern and a small form factor. The proposed antenna has a peak gain of 8.1 dBi with a stable radiation pattern. An average of 4 dB and a peak of 7.5 dB in-band RCS reduction are shown by the suggested antenna.

摘要

In this work, a unique antenna intended for Wireless Body Area Network (WBAN) applications is presented. To increase its bandwidth and handle several frequency bands, the suggested antenna makes use of slotting and multi-resonant radiators with capacitive coupling. The Characteristic Mode Analysis (CMA) technique achieves the antenna’s high-Q resonance bandwidth while maintaining other spectral properties. The 2.4–2.6 GHz impedance bandwidth WLAN bands are serviced by the designed antenna, which has a directed radiation pattern and a small form factor. The proposed antenna has a peak gain of 8.1 dBi with a stable radiation pattern. An average of 4 dB and a peak of 7.5 dB in-band RCS reduction are shown by the suggested antenna.
