Provided in the embodiments of the present application are an antenna oscillator, an antenna, and a communication device. The antenna oscillator comprises four radiators and four feed structures, wherein the feed structures are connected to the radiators and are used for feeding the radiators; each radiator comprises a first transmission line, a first radiation arm, a second radiation arm and a second transmission line, which are connected in sequence, and the first transmission line and the second transmission line are respectively connected to the feed structures; the four radiators are a first radiator, a second radiator, a third radiator and a fourth radiator, the first radiator and the second radiator radiate signals in a first polarization direction, and the third radiator and the fourth radiator radiate signals in a second polarization direction, thus forming a dual-polarized antenna oscillator; and each feed structure is a one-to-two feed structure, and two radiators are connected in parallel and are connected to the same feed structure. By means of the solution, the aperture of an antenna can be reduced, and the gain of the antenna can be improved. Moreover, each radiator has two current distribution modes, and thus a bandwidth is relatively large.
