• Technology, SE-41296 Gothenburg, Sweden 10.3762/bjnano.13.27 Abstract Modeling of a broadband receiving system based on a meander series of Josephson YBaCuO grain boundary junctions integrated into a log-periodic antenna was carried out. The electromagnetic properties of the system, namely amplitude
