In order to support beyond fifth-generation (5G) cellular communication at millimeter-wave (mmWave)/THz, high gain antennas with sufficient bandwidths (BWs) are needed. In this research paper, novel microstrip antenna's gains with a peak gain of more than 24 dB for sixth-generation (6G) cellular communication at a resonance frequency of 112.5 GHz are suggested and investigated. A couple of microstrip array antennas has been modeled and simulated based on Rogers RO3003 microstrip laminates, with the electromagnetic (EM) commercial simulator through a Finite Integration Technique (FIT) solver at the CST MWS simulator. The first one has been within 36×32 radiators in serial and corporate feeding without Frequency Selective Surfaces (FSSs). Besides the 36×32 radiators in serial and corporate feeding, the second one has included 2-28 bandstop FSSs in order to enhance the antenna's gain. The first antenna's simulation results have been compared with the simulation with the EM commercial simulator through the Finite-Element Modeling (FEM) solver at the Ansys HFSS simulator, and a fair concurrence has been achieved to support the proposed designs. The peak simulation results of the directivity, gain, BW, and total efficiency for the first and second proposed antennas obtained are 27.27 dBi, 25.7 dB, and 24.89 GHz (22.6%), 77.95%,27.2 dBi, 25.74 dB, 18.3 GHz (16.2%), 77.95%, respectively. These results show that the suggested designs are a potential candidate for 6G cellular communication antennas at the mmWave/THz band. [ABSTRACT FROM AUTHOR] |
