We show that the plasmon frequencies in a one-dimensional dense array of doped (or gated) graphene nanoribbons can be changed through the entire terahertz range depending on the angle between the plasmon wave vector and the nanoribbon direction. The overdamped regime for oblique plasmons in the graphene nanoribbon array is discussed.
