  Title Characterization of a planar self-complementary square-spiral antenna in the THz region Type Journal Article
  Year 2006 Publication Microwave and Optical Technology Letters Abbreviated Journal Microwave Opt Technol Lett  
  Volume 48 Issue 3 Pages 524-529  
  Keywords optical antennas; square spiral antenna; self complementary THz; photomixing; lens; method of moments; geometric optics; physical optics  
  Abstract This paper describes a compact, self-complementary square-spiral antenna on a GaAs substrate with a broadside high-directivity (~9 dB) frequency-independent pattern when coupled through a silicon hyperhemisphere. The driving-point resistance undulates between ~00 and 300Ω from 200 GHz to 1 THz—much higher than the 72Ω value from Booker's modified formula, but quite beneficial for coupling to high-impedance broadband devices

  Title Infrared microstrip dipole antennas Type Journal Article
  Year 2001 Publication Microwave and Optical Technology Letters Abbreviated Journal Microw Opt Technol Lett  
  Volume 29 Issue 6 Pages 381-383  
  Keywords optical antennas  
  Abstract Abstract 10.1002/mop.1184.abs We report on the successful use of niobium microbolometers coupled to microstrip dipole antennas for the detection of midinfrared radiation. Measurements of the detector response versus antenna length performed at the 10.6 μm wavelength allowed us to identify the first three current-wave resonances along the antenna arms. The detector response was also measured as a function of the radiation wavelength in the 911 μm spectral domain. Excellent agreement between the experimental results and finite-difference time-domain (FDTD) predictions was obtained.
