In this paper, we have designed various shapes of patch antennas like Rectangular patch antenna, U-shaped, E-shaped and Rectangular shaped vertical slot antenna which is resonated at 0.7THz–0.8THz. The main theme of this paper is to overcome the major disadvantages of basic microstrip patch antenna like narrow bandwidth, high return loss etc. The recent improvements in wireless technology give a big challenge to design a patch antenna which results in wide bandwidth, low loss and better efficiency at terahertz region. The performance of various shapes can be analyzed by different parameters like Return loss, VSWR, Radiation pattern. In this parametric study, we have investigated and found that among all the configurations the Rectangular shaped vertical slot antenna yields better performance and having a return loss of −32db and it resonates at 0.75THZ. Terahertz antennas which find its applications in satellite communications, civil and military applications. The proposed antennas are designed and simulated by using a finite element method based electromagnetic solver, Ansys-High-Frequency Structure Simulator Software(HFSS). |
