Abstract :
Performance of the antenna-coupled detectors was measured by the quasi-optical setup in wide frequency range from 0.1 to 1.0 THz. Studied sensors were based on the titanium microbolometers coupled with the double-dipole- or log-periodic-type antenna for room temperature THz detection. The THz radiation of the selectively filtered broadband LTG-GaAs photoconductive emitter and the system generating narrow band THz bursts were used for measurements.
