Best Substrate for VHF applications

  1. Jan 14, 2014 #1
    Hi buddies,
    i am working on very high frequencies antenna applications. can any body 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).
