Dual-polarized broadband oscillator and antenna

The invention discloses a dual-polarized broadband oscillator and an antenna. The oscillator comprises a first radiation unit, a second radiation unit, a first air microstrip line, a second air microstrip line, a coaxial cable and a reflecting plate. A metal plate material is adopted as a main material of the dual-polarization broadband oscillator, the design cost is reduced while the requirement for light weight is met, a first radiation unit and a second radiation unit are arranged on a reflecting plate in a targeted mode according to the metal plate material, and a feed space for orthogonally arranging a first air microstrip line and a second air microstrip line is constructed. According to the invention, conditions are created for the requirement of miniaturization, oscillator array superposition is conveniently realized, the requirement of multiple use scenes of a user is met, multi-frequency-band coverage is realized, the frequency band gain is not influenced, and the requirement of multiple use scenes
