Best Substrate for VHF applications

Click For Summary
SUMMARY

The optimal substrate materials for very high frequency (VHF) antenna applications, particularly in the THz and optical bands, are high-resistivity silicon and sapphire. These materials exhibit low losses, making them suitable for advanced antenna designs. Additional substrates may also be effective, but silicon and sapphire are the most widely recognized in the field. Researching THz detectors integrated with log-periodic antennas can provide further insights into substrate performance.

PREREQUISITES
  • Understanding of THz frequency applications
  • Familiarity with antenna design principles
  • Knowledge of substrate materials and their properties
  • Experience with experimental methods in high-frequency research
NEXT STEPS
  • Research high-resistivity silicon properties for VHF applications
  • Explore sapphire as a substrate for THz antennas
  • Review academic papers on THz detectors and log-periodic antennas
  • Investigate alternative substrates for low-loss performance in optical bands
USEFUL FOR

Engineers and researchers working in high-frequency antenna design, materials scientists focusing on substrate properties, and anyone involved in THz technology development.

Hi buddies,
i am working on very high frequencies antenna applications. can anybody updates me about best suitable substrate material which exhibits low losses at THz and optical band. i appreciate that.

It will depends on the details. From what I remember you should probably look at high-resistivity silicon or sapphire.
There are also quite a few other substrates that should work, but I believe Si and sapphire are the most common ones.

Have a look at some papers on THz detectors (especially experiments with e.g. detectors integrated in log-periodic antennas).
