Zusammenfassung:In this paper, a triple band graphene elliptic patch antenna is designed for operation in 4 THz, 4.95 THz and 7.75 THz. The main idea of this paper is to partition the graphene patch into pieces to have more degrees of freedom to reconfigure the polarization of the antenna. The antenna’s polarization is controlled by partitioning the patch into 9 elements, polar griding, resizing them, and changing their chemical potential. The main operation mode of the antenna has linear polarization in its boresight in 4 THz and 7.75 THz but circular polarization in 4.95 THz. Circular polarization in 4 THz and 7.75 THz is reached in four different modes; each mode has its own advantages. The main purpose is to achieve some modes that have minimum radiation efficiency loss. In these modes, LHCP and RHCP are reached in a single pattern.
