Description
Technical field
The present invention relates to a kind of mobile communication antenna, more particularly, to a kind of multifrequency sharing base station antenna and its antenna-reflected
Plate.
Background technology
With the fast development of mobile communication, the communication network of different systems needs to build a station on a large scale, multifrequency community antenna
Can effectively solve the problem that multipath fading, reduce antenna amount, reduce antenna cost.Site and antenna resources can be saved, altogether simultaneously
Co-located multifrequency community antenna of standing is increasingly becoming the first-selection of carrier network construction.
In prior art, multifrequency community antenna group battle array is mainly two kinds of structures：
One kind is coaxial nested scheme, and program medium and low frequency radiating element is coaxial with high frequency radiating element to be arranged on reflecting plate
Same axis on, using arranging up and down between two row high frequencies or staggered at grade.As applied for, notification number is
The patent application of CN103094715A, discloses a kind of multifrequency community antenna and system, and this antenna includes reflecting plate and is arranged on
First frequency radiating curtain on reflecting plate and second frequency radiating curtain, described first frequency is more than second frequency；Described
Two frequency radiating curtains have two generally vertical parallel first axles and second axis；Described second frequency radiating curtain bag
Include at least three second frequency radiating elements, described at least three second frequency radiating elements are laid in first axle and the second axle
On line, at least provided with a second frequency radiating element, described three second frequency radiating elements are in axis substantially for every axis
Between on orthogonal direction, mistake is spaced apart；Described first frequency radiating curtain includes at least one first frequency radiating element, described
Multiple first frequency radiating elements are arranged on first axle；On second frequency radiating element on first axle and first axle
Part first frequency radiating element is nested to be used.Which reflects the coaxial setting of low frequency radiating element and high frequency radiating element.Also
Just like the patent application for CN102157780A for the application publication number, it discloses a kind of multi-mode antenna, including reflecting plate and set
Dual-band antenna group on this reflecting plate and single-band antenna group, described dual-band antenna group is two rows dual-band antenna arranged in parallel
Array, described dual-band antenna array further includes high frequency antenna unit and the low-frequency antenna unit of coaxial line group battle array, described
