Study and Design of a Printed Microstrip Antenna in the Terahertz Band

The terahertz domain is an increasingly studied frequency range due to the particular properties of this radiation. The low energy of the photons makes them ideal for medical imaging, non-destructive testing in industry and the study of the stars surrounding us. The frequencies involved could also be used to increase telecommunications throughput, an important area of research at present. This latter aspect is the subject of this chapter. Indeed, to improve throughput, it is necessary to find and optimize new sources and antennas. The technological development of portable intelligent devices and very high-speed terahertz (THz) communication systems requires high-performance, low-cost antennas with low volume and high directivity to reduce propagation losses in the THz range. To this end, we propose a new printed antenna for applications in the THz frequency range. This antenna delivers best-in-class performance, such as a reflection coefficient of less than − 10 dB and a bandwidth of 24.21 GHz. These results are based on simulations carried out using the HFSS tool. With this software, they design high-frequency electronic products. This work uses the ground plane deformation technique to optimize size and thus improve bandwidth.
