Hypothesis
Can a dual-polarized reflectarray antenna using LTCC technology achieve high gain and wide bandwidth in the D-band?
Conclusion
The proposed reflectarray antenna achieved peak gains of 32.25 and 33.03 dBi for two orthogonal polarizations with significant bandwidth.
Supporting Evidence
- The antenna achieved a peak gain of 32.25 dBi for one polarization and 33.03 dBi for the other.
- The measured 3 dB gain bandwidths were 122–149 GHz and 123–149 GHz for the two polarizations.
- The design utilized low-temperature co-fired ceramic technology for better performance.
Takeaway
This study created a special antenna that can send and receive signals really well at high frequencies, making it great for fast wireless communication.
Methodology
The study involved designing, fabricating, and measuring a D-band reflectarray antenna prototype using LTCC technology.
Limitations
The measured performance was lower than simulated results due to dielectric loss, feed source excursion, and machining errors.
