Implementing the single/multiport tunable terahertz circularly polarized dielectric resonator antenna
TL;DR: In this paper , an aperture coupled terahertz rectangular dielectric resonator antenna operating with the fundamental magnetic dipole is designed, where the modal field distribution is perturbed using the material-perturbation technique and the electric field vectors are aligned in the horizontal plane with their orthogonal components having quadrature phase difference between them.

Tuning the higher to lower order resonance frequency ratio and implementing the tunable THz MIMO/self-diplexing antenna
TL;DR: In this article , the frequency ratio of higher to lower order mode can be electronically tuned in a terahertz (THz) antenna with metallic radiator using a graphene loop, and the desired impedance matching can be achieved at the frequencies of any two resonances at a time by selecting an appropriate value of μ c .

Excitation of Higher Order Modes in Terahertz Antenna Using Graphene Strip
TL;DR: In this paper , a terahertz (THz) antenna is implemented with a technique of achieving the multiband response by exciting the higher order modes without changing the antenna structure, and a patterned triangular shaped THz microstrip patch radiator is designed and numerically analyzed for providing the dual-band response with TM10 and TM20 modes.
