Description
Technical field
The utility model is related to antennas, and in particular to it is a kind of improve base station before and after ratio lateral boundaries be city wall shape antenna.
Background technology
Antenna for base station is the important component of mobile communication system, and the electric signal that transmitter exports is converted to space by it
Electromagnetic wave, or spatial electromagnetic wave is received and converted to electric signal and enters receiver, characteristic directly affects entire wireless network
The overall performance of network.In mobile radio communication engineering design, it should be distributed according to the covering requirement of network, telephone traffic, is anti-interference
It is required that reasonably selecting antenna for base station with actual conditions such as network service qualities.
As in microwave transmission chain receive, emit signal antenna, distribution of the space radiation power in space --
Directional diagram is very important index.A kind of effective solution method for increasing system communication capacity is the base using ratio before and after height
Station antenna.
Relatively low before and after traditional antenna for base station, orientation receives that performance is poor, and the back lobe of antenna, which is possible to generate, gets over area and cover
Lid causes handoff relation chaotic, generates call drop.In order to meet than requiring before and after height, Antenna Design is generally used in industry
Method；Increase reflective back plane at the antenna back side.This more universal method can bring two kinds of most important adverse consequences, and one
It is the increase of manufacturing cost；Second is that the weightening of antenna for base station.
Utility model content
Purpose of utility model：The utility model provide it is a kind of improvement base station before and after ratio lateral boundaries be city wall shape antenna,
It solves relatively low before and after existing antenna, easily leads to handoff relation confusion, signal easily interrupts, and antenna structure is complicated, and weight is big to ask
Topic.
Technical solution：The lateral boundaries of ratio are the antenna of city wall shape, including day before and after improvement base station described in the utility model
Line reflection plate, affiliated antenna-reflected plate include reflecting surface and are arranged the lateral boundaries in reflecting surface both sides, on the reflecting surface uniformly
It is arranged at intervals with several radiating elements, the lateral boundaries are city wall shape, and regular alternate intervals are provided with greatly in the side circle
Boss and small boss.
In order to facilitate setting radiating element, lateral inner boundary and vertical inner boundary, the cross are provided on the reflecting surface
Reflecting surface is separated into several grids to inner boundary and vertical inner boundary are crisscross, the radiating element is arranged in the grid
It is interior.
For the ease of control base station antenna consistency, convenient for large-scale production, the reflecting surface is integrated folding with lateral boundaries
It is curved to form.
It is with+45 ° of polarization or -45 ° of polarized bowl-shape oscillators to make antenna miniaturization, the radiating element.
In order to enable big boss to effectively improve the main polarization front and back ratio of antenna for base station, small boss can effectively improve cross polarization mirror
Not rate, the big boss are arranged in the lateral boundaries between the unit of two adjacent radiation, and small boss is arranged in each radiation
In the middle part of unit in corresponding lateral boundaries.
In order to make big boss couple with radiating element to improve the main polarization front and back ratio of antenna for base station, the big boss is higher than
20 ± 1mm of boundary is surveyed, the length of big boss is 42 ± 1mm.
In order to make small boss couple with radiating element to improve antenna for base station cross polarization discrimination, the small boss is high
In 10 ± 1mm of lateral boundaries, the length of small boss is 20 ± 1mm.
Advantageous effect：The utility model improves front and back ratio, and the orientation for improving antenna for base station receives performance, and more area is avoided to cover
Lid, is not easy call drop；Improve the indexs such as antenna for base station beam angle, ensures the stabilization of antenna overall performance, miniaturized structure, weight
It is low.
