Problem addressed
Current high-gain terahertz (THz) antennas based on horn or lens antennas are bulky in size, while conventional technologies used for high-gain antenna arrays are difficult to scale down to THz. The high-gain ORA has a small thickness of about 2.5 free space wavelength that is suitable for on-chip integration with other components to form a wireless system for future 6G communications needs.
Innovation
- The imprint and deep reactive ion etching technologies are developed to realize a THz ORA with a complementary antenna feed and Gaussian beam.
- With high precision technologies and smooth morphology, this THz ORA has much reduced low profile and low side lobes compared to horn and lens antennas.
- The antenna has a high gain of 20.3 dBi, and the silicon-based fabrication technology is compatible with compact ultra-high-speed wireless systems.
Key impact
- High gain
- Lower surface roughness
- Low side lobe level
- Potential application of dielectric test in THz
