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%
Different diode areas responsivity response A = 0.43 , Area = 0.31mm2 A = 0.38 , Area = 0.28mm2 Old detector (A=4.14)
