A partial slotted curved waveguide leaky-wave antenna which can generate orbital angular momentum (OAM) mode-groups (MG) with high equivalent OAM order negative and positive 40 at 60 GHz is proposed in this paper. The proposed antenna with partial slotting is designed according to the circular traveling-wave antenna which can generate single conventional OAM wave, so it can be regarded as partial arc transmitting (PAT) scheme compared with the full 2pi aperture slotting of the circular…
