Abstract: An electrodynamic simulation of a mixer system with a heterodyne based on a high-temperature superconducting (HTS) Josephson junction on a single chip has been performed. A new system design has been proposed as a mixer, combining a log-periodic antenna and a Vivaldi antenna, which has shown promising results in transmitting a reference signal for frequencies up to 125 GHz. The directivity and gain of the antenna at a frequency of 100 GHz were 6.51 and 6 dBi.

Keywords: high temperature superconductivity, radiation pattern, log periodic antenna.
