Disclosed are an antenna radiation unit and an antenna. The antenna radiation unit comprises a pair of crosswise disposed vibrators and parasitic unit assemblies. Each parasitic unit assembly is disposed in an included angle formed by adjacent two vibrator arms of the crosswise disposed vibrators. The parasitic unit assembly is fixedly connected to the vibrator. A radiation signal transmitted by the vibrator is reflected and converged by means of the parasitic unit assembly. In the embodiments of the present invention, an antenna radiation unit can be formed by disposing additional parasitic unit assemblies at the periphery of a pair of crosswise disposed vibrators, the structure of the antenna radiation unit is very simple, can be formed by directly using a metal sheet part, and is convenient to treat and manufacture. In the embodiments of the present invention, secondary reflection and convergence are performed, by means of a parasitic unit assembly, on a radiation signal transmitted by a vibrator, and new radiation is generated, which helps to expand the caliber of an original vibrator and converge the width of a surface beam of the whole antenna, and accordingly, the effect of reducing the volume of the whole antenna is achieved; the antenna has a simple structure and a light weight, thereby reducing production and repair costs. |
