In this paper, a frequency selective surface (FSS) with tunable bandstop performance by integrating graphene is discussed. The graphene implanted in the circular FSS unit makes the transmission and reflection bands of the proposed FSS tunable owing to its alterable complex conductivity controlled by the chemical potential. The transmission zero of the proposed FSS performing as a reflection plane happens at the frequency from 1.65 THz to 2.19 THz when the chemical potentials of graphene change from 0 eV to 1 eV. Moreover, reconfigurable radiation pattern of a traditional dipole antenna is accomplished loaded with the proposed FSS by altering the complex conductivity of graphene. The dipole has a directional radiation pattern with enhanced directivity at 2.1 THz by adding the proposed FSS with μc = 0.8 eV. However, the omnidirectional radiation pattern is maintained by changing the value of chemical potential to 0 eV while the FSS is nearly transparent. Therefore, a radiation diversity property could be achieved by controlling the chemical potential of graphene loaded in FSS.

We realized graphene‐based optical leaky wave antenna as an alternative to simple optical leaky wave antenna. The use of graphene in designing optical leaky wave antenna provides improved directivity. Tuning of this sharp directive pattern can be used for beam shaping of an optical antenna. The graphene layers are loaded in Si3N4 waveguide. The graphene layers are excited by a fixed voltage. Our results lead to graphene‐based design in the third window of optical communication. In addition, graphene‐based leaky wave design gives enhancement in different antenna parameters like reflection coefficient, transmission coefficient, and gain. The proposed graphene designs have directive response with high efficiency and are envisioned to become building blocks of several infrared systems which is going to be applicable in medical sensing systems.

Abstract-Ultra-wideband (UWB) antennas have advantages such as high data rates, improved multipath resistance and low power consumption. In this work, UWB patch antennas based on electrically conductive adhesive were manufactured with a simple technique and evaluated in the laboratory. Results showed that the thickness of the samples ranged from 207 to 261 µm. The bandwidth optimization obtained was 200% compared to a traditional copper-layer antenna. UWB antennas showed an average bandwidth of 8.558 GHz in the region 609 MHz to 9.105 GHz. The antennas covered the whole of UHF band, L band, S band, C band and part of X band. Finally, the proposed technique allows reducing the size of patch by 70% for low frequencies of operation, while achieving a similar performance.
