[The future 6G wireless communications will need the definition of new spectral bands and the employment of novel advanced physical layer solutions. The millimeter-wave (mmWave) frequency bands have been allocated for the fifth generation (5G) of cellular systems, while additional mmWave sub-bands have been assigned as well. The need to support higher data rates than 5G in the order of terabits per second requires more bandwidth. However, the total consecutive available bandwidth in mmWave bands is still less than 10 GHz, so such data rates cannot be supported. In this context, future 6G communication systems require the use of the terahertz communication band (0.1–10 THz). The THz band is envisioned as a critical wireless technology for meeting future demands in 5G and beyond. For several years, there has been a lack of THz transceivers and antennas, so that the THz band has become one of the electromagnetic (EM) spectrum’s least studied frequency ranges in terms of wireless communication. However, the need for 6G communication systems has redefined the requirements for THz antennas. In this book chapter, we provide a complete framework for circular polarized antenna design in the low THz band. This optimization framework is based on a swarm intelligence algorithm, namely, the salp swarm algorithm (SSA). The numerical results show that the SSA has been successfully applied in designing antenna with wide band operation and circular polarization.]
