Disclosed are a three-dimensional multi-directional controllable radiator, and an antenna. The radiator comprises a rectangular cavity, a rectangular plate and a rectangular waveguide, wherein the rectangular plate covers the bottom face of the rectangular cavity and is provided with a feed slot; the feed slot is connected to the rectangular waveguide; and a radiation slot is provided on at least one face, apart from the bottom face, of the rectangular cavity. The antenna comprises a bias circuit and the three-dimensional radiator, wherein a PIN diode is integrated on the bias circuit; and the radiator is connected to the bias circuit. According to the three-dimensional radiator of the present invention, characteristics, such as three-dimensional directional controllability, high power capacity, low insertion loss and simple design and processing, can be met, and a beam-tunable antenna can be designed by means of connecting a bias circuit including a PIN diode; and the antenna of the present invention can rea
