This paper proposes a graphene-based toothed log-periodic antenna for the THz frequency region (0.1–10) THz applications. By adjusting the applied DC voltage on the graphene, the antenna's properties, such as bandwidth, radiation pattern operational frequency ranges have been shifted. The chemical potential, surface conductivity, and surface impedance of the graphene are affected by changing applied DC voltage and hence a reconfigurable antenna has been resulting. The suggested antenna's radiating element is from a graphene material and has log-periodic shape, with 50 ohm feed line placed on the grounded silicon dioxide substrate, 1 µm-thick layers of silicon crystalline and alumina on top of the substrate. The antenna is simulated by the computer simulation technology (CST) 2020 software program. The resultant bandwidth (7-10) TH has a return loss of less than -10 when the chemical potential of graphene is 1eV.

This paper presents ultrawide band (UWB) Cage Dipole Antenna, designed and developed for ultra high frequency band ground penetrating radar (GPR) system. The presented cage antenna consists of two thick diverging cages composed of 10 cylindrical metallic rods. It operates at 500 MHz center frequency and provides 105% impedance bandwidth for |S11| <−10 dB. Antenna has donut‐shaped radiation pattern and provides 2.6‐dBi gain at center frequency. Impedance variation of designed Cage dipole antenna has been matched using wideband lumped component‐based balanced to unbalanced (Balun) network. Integrated analysis of cage dipole antenna and Balun network has been carried out in 3D electromagnetic simulator and analyzed results are presented. Moreover, metallic mount with Teflon bush has been designed to support the cage dipole antenna during far‐field characterization and its effect has also been taken into account during the analysis. Time‐domain analysis of proposed Cage dipole has been carried out and its results are presented in detail. Presented cage dipole antenna provides suppressed late ringing, making it best suitable for GPR applications.
