Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] An embodiment of the present invention provides a new type of antenna radiating unit, which is arranged above the reflector, such as figure 1 As shown, the radiating unit includes: two supporting components 10 and 11 intersecting each other, a radiating surface 12 and a corresponding feeding part 13; the radiating surface includes: two pairs of mutually orthogonal dipole radiating arms 121 , 122, 123, 124, and at least one parasitic device 14, the parasitic device 14 is disposed on the periphery of a pair of the radiation arms, such as the radiation arms 122 and 124. Preferably, the peripheries of the two pairs of mutually orthogonal dipole radiation arms may contain parasitic devices. Wherein, the parasitic device is an extended component corresponding to the radiation arm, thereby reducing the size of the original radiation arm and achieving...

Abstract

The invention relates to a novel antenna radiation unit. The novel antenna radiation unit is arranged above a reflective plate; the novel antenna radiator unit is characterized by comprising two intersecting supporting parts, a radiation surface and a corresponding feed part; the radiation surface comprises two pairs of orthogonal dipole radiation arms, and at least a parasitic apparatus, wherein the parasitic apparatus is arranged in the periphery of the radiation arms. The antenna, by adopting the radiation unit disclosed by the invention, can effectively solve the problems of narrow bandwidth and low isolation degree in the prior art, and can achieve an effect of decoupling and resonance eliminating in the multi-band antenna.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a novel antenna radiation unit and a multi-frequency antenna. Background technique [0002] Antennas play a vital role in base station systems for communications. The radiation unit is an important part of the base station antenna and a key component that affects the performance and size of the base station antenna, so its performance also indirectly affects the quality of communication. Especially at the current stage, the demand for antennas in the market not only lies in the excellent radiation performance and electrical performance, but also puts forward higher requirements for the size of the antenna. In the prior art, for example, an antenna and its radiation unit disclosed in US Patent Publication No. US7,053,852B2 uses two pairs of dipole units parallel to each other to form two radiation units with orthogonal polarization. The antenna in this form has...
