Abstract

The advancement in the wireless communication technology showcases a substantial interest towards reconfigurable antennas due to their vast applications in different wireless and radar communication systems. Their properties can be adjusted in order to obtain the desired radiation pattern direction, frequency-band or polarization. In this work, a graphene-silicon ceramic based dual-port frequency reconfigurable polarized array antenna is structured and evaluated. An aperture is utilized to feed the silicon ceramic with an aperture and a 3-dB wideband power microstrip divider power divider is used to provide half the input power at each of its output ports and convert it into an efficient array structure. The antenna employs an aperture-coupled feeding mechanism and a 3-dB wideband microstrip power-divider to efficiently distribute input power between two orthogonally polarized ports, enabling polarization diversity with improved isolation exceeding 30 dB. By dynamically tuning the chemical potential of graphene, the antenna achieves frequency reconfigurability across a broad THz band (approximately 0.78–1.17 THz), providing peak gains up to 9.1 dBi and excellent return loss performance better than –28 dB. The use of a low-loss silicon ceramic substrate enhances radiation efficiency and mechanical stability. Simulation results obtained from both CST Microwave Studio and HFSS confirm the antenna’s high performance, consistency, and robustness. The proposed design offers significant advantages over traditional fixed-frequency antennas.
