A new analytical model for log-periodic Terahertz antennas

In this paper a novel model about the principle of operation of log-periodic Terahertz (THz) antennas is proposed. In the theoretical part analytical calculations are opposed to the results of electromagnetic field simulations. For the experimental validation of the novel theory large-scale models in the GHz range were investigated. All considered antenna structures exhibit an excellent coincidence between calculations, simulations and measurements.
