100GHz antennas’ characteristics

  • Horn antenna
  • (diameter=2cm (dm), length= 5.5cm (L))

Gain = 295 = 24.27 (dB)

Aeff = 211.3mm2 => D = 8.2mm

  • Lens antenna

Gain = 335.7 = 25.27 (dB)

Aeff = 240.5mm2 => D = 8.75mm

Including losses: Ohmic:10%, Air/dielectric interface:30% , Back (air) radiation: 9%

slide4

Different diode areas responsivity response

A = 0.43 , Area = 0.31mm2

A = 0.38 , Area = 0.28mm2

Old detector

(A=4.14)
