However, either quasi-optical configurations or the characteristics of typically used antennas as well as temperature-dependent nonlinear frequency sweeps restrict the achievable spatial resolution and reliability of these systems. In this contribution we report on the implementation of a dielectric rectangular rod antenna and a software-assisted feedback control loop to overcome these limitations.enantennaradio transceiverterahertz wave detectors621conference paper
