Abstract
Using CST MWS 2023 software, modeling of the S-parameters and the radiation patterns (RPs) of antenna arrays (AAs) based on rectangular graphene microribbons in the THz range has been carried out. It is shown that the unique property of graphene AAs is the possibility of electronic frequency scanning and multiband operation regime, as well as an increase in the gain factor, narrowing of the main RP lobe, a decrease in the level of the side RP lobes with an increase in the value of the chemical potential (from 0.2 to 1.0 eV), and their dependences on the number of AA emitters.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
