Hypothesis
Can a filtering antenna-filtering antenna (FA-FA) structure achieve a wide passband and sharp roll-off characteristics in frequency-selective surfaces?
Conclusion
The proposed FA-FA-based frequency-selective surface demonstrated a wide passband from 13.06 GHz to 14.46 GHz with sharp roll-off characteristics.
Supporting Evidence
- The FA-FA-based FSS achieved a wide passband and high selectivity.
- The lower and upper roll-off bandwidths were sharp, reaching 1% and 1.2% of the center frequency.
- The design allows for easy integration of active devices for reconfigurable functions.
- Simulation and measurement results showed good agreement, indicating reliable performance.
Takeaway
This study created a special surface that can let certain radio waves pass through while blocking others, which is useful for improving communication systems.
Methodology
The study involved designing a dual-polarized filtering antenna and constructing a frequency-selective surface by arraying these antennas.
Limitations
The study did not address potential impacts of the experimental design and manufacturing errors on the results.
