Ultra-Compact Low-Pass SSPP Filter

Ultra-Compact Low-Pass Spoof Surface Plasmon Polariton Filter Based on Interdigital Structure

Micromachines, 2023 · First Author

https://doi.org/10.3390/mi14091687

  • Proposed the concept of an ultra-compact low-pass SSPP filter based on interdigital structure and designed the overall experimental scheme.
  • Conducted simulations and studied the reduction in asymptotic frequency and unit size brought by the interdigital structure.
  • Fabricated a prototype and validated a 0-5.66 GHz passband, over 24 dB out-of-band suppression in 5.95-12 GHz, and sharp roll-off near 5.74 GHz.
Textile Bandwidth-Enhanced HMSIC Antenna

Textile Bandwidth-Enhanced Half-Mode Substrate-Integrated Cavity Antenna Based on Embroidered Shorting Vias

Micromachines, 2024 · Co-author

https://doi.org/10.3390/mi15091081

  • Studied the effect of adding two shorting vias through theoretical analysis and HFSS simulations.
  • Designed and fabricated a textile bandwidth-enhanced HMSIC antenna with a 4.87–6.17 GHz impedance band, over 97% radiation efficiency, and maximum gain above 7.6 dBi.
  • Performed SAR simulations to evaluate robustness near human tissue and on-body electromagnetic safety.
