Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0018] Such as figure 1 , the broadband dual-polarized antenna unit in this embodiment includes a reflector O1, a support column O2, a loading section O3, a radiation sheet O4, a first excitation metal sheet O5, a second excitation metal sheet O6, a first insulating block O7, and a second excitation metal sheet O6. Two insulating blocks O8 and a fixed base O9 are formed, and four radiation pieces O3 are symmetrical and perpendicular to each other, and together with the support body O2 constitute the radiation body of this embodiment. The radiator dielectric material is aluminum alloy.

[0019] The reflector O1 is a metal plate, which is used to fix the radiator and also to reflect electromagnetic waves, ...

Abstract

The invention discloses a broadband dual-polarized antenna unit, which is used for realizing broader band characteristic. A radiating element comprises a reflective plate, a main radiating body, an upper insulating block, a lower insulating block and a balance feed device, wherein the main radiating body comprises a support body and radiating pieces; four radiating pieces and the support body form a whole, and the four radiating pieces respectively form an angle of 90 degrees with the support body; the outline of each radiating piece has a 90-degree fan shape; each radiating piece is provided with a hollowed structure and a loading section used for broadening the bandwidth and improving polarization purity; a clearance between two adjacent radiating pieces is less than 0.1 wavelength; and the radiating element adopts coupling balance feed and an integrated design that four support body bottoms are mutually short-circuited, and is fixed on the reflective plate. The broadband dual-polarized antenna unit has impedance bandwidth of over 45 percent, and has the advantages of small size, simple structure, a few components, convenience for assembly, easy production, low cost and the like.

Description

[technical field] [0001] The invention relates to the field of mobile communication base station antennas, in particular to a broadband dual-polarization antenna unit. [technical background] [0002] With the maturity of the 3G industry chain, since 2008, the 3rd generation mobile communication system (3G) has entered into large-scale network deployment and commercial use in China. Mobile communication plays an increasingly important role in people's daily life. As of October 2010, the total number of mobile communication users in my country reached 805 million, of which 3G users reached 25.2 million, and more than 2 million base station antennas were put into use vice. With the continuous increase of various mobile communication services and types, the requirements for data transmission rates are also getting higher and higher, and the corresponding working frequency bands of various communication systems are also expanding. The working frequency of smart antenna in TD-SCD...
