Abstract

Here, two different THz radiating structures are analyzed, consisting both of a central slot surrounded by annular or straight corrugations. Concentrically grooved antenna presents a moderately high gain. Its radiation and temporal properties are analyzed both numerically and experimentally. For the second case, no appreciable differences in terms of radiation characteristics are observed when the grooves´ profile is changed from square to triangular. Manufactured triangular grooves antenna shows good performance for the experimental measurements at 0.5THz. These results could be of interest for the development of new THz sources and detectors.
