Direct detection mm/sub-mm wave warm-carrier bipolar narrow-gap Hg1−xCdxTe semiconductor bolometers that can be used as sensitive elements in THz sensitive arrays, are considered. The response of Hg1−xCdxTe warm-electron bolometer was measured in ν=0.037−1.54 THz frequency range at T=68-300 K. In the detector (bolometer) considered the electromagnetic wave heats electrons and holes there, creates...
This paper presents a study of the radiation efficiency measurement of antennas using the source stirred chamber (SSC) method. The antenna under test (AUT) was a coplanar-line-fed monopole. By using the minimum value of the input resistance of the antenna in the chamber under different stirring configurations and introducing frequency stirring technique, the resonance effect can be greatly reduced...
The increasing interest in using Near Field Communications (NFC) technology at 13.5MHz is growing rapidly in the area of contactless payments, as well as numerous other applications, between devices that are within 10cm distance apart. However, there is growing concern that the use of such devices for contactless payments invites problems with regards to using metallic objects in the vicinity of the...
In this paper we will present our latest research results of integrated quantum dot Schottky diodes and integrated silicon antenna for RF applications. Both, the quantum dot Schottky diodes and the antenna are integrated on Si substrates forming a simple mm-wave detection system, the rectifying antenna (RECTENNA). Within this work a specific antenna design, 1-dimensional array (single line antenna),...
