Description
Technical field
This utility model relates to antenna of mobile communication base station field, particularly relates to a kind of M type reflecting plate antenna for base station.
Background technology
The development of mobile communication technology is maked rapid progress, and the competition of Telecom Service Market increasingly sharpens, and mobile broadband demand is constantly promoted by user, and electromagnetic environment also becomes increasingly complex, and these bring unprecedented challenge to the design of mobile communication antenna feed system. On the one hand the electric property of antenna for base station being proposed increasingly higher requirement: broadband, high-gain, high front and back ratio, the convergence of high-isolation, wave beam, main shaft cross polarization discrimination requires more than 20dB, and �� 60 �� of cross polarization discriminations require more than 10dB; Require that antenna for base station volume is little, lightweight, cost is low and good looking appearance and surrounding coordination etc. on the other hand.
At present, being limited to current technical merit, the design of directional base station antenna is difficult to meet above many requirements simultaneously, needs urgently to propose new design to improve the performance of product.
Utility model content
This utility model provides one to have ratio before and after height, and cross polarization discrimination index is good, and horizontal plane beam angle is restrained, it is adaptable to the base station directional antenna of 3G and 4G mobile communication system.
To achieve these goals, M type reflecting plate antenna for base station disclosed in the utility model includes: reflecting plate, some radiating elements, feeding network. Described reflecting plate is a metallic plate in M type structure; Several radiating elements form uniform straight line array by the front being equidistantly arranged in described reflecting plate, and the flange of M type reflecting plate is parallel with radiating element orientation; Being placed with a metal baffle between adjacent radiation unit, radiating element both sides are respectively placed with a metal strip parallel with reflecting plate flange; Feeding network is arranged at the back side of M type reflecting plate, for providing parallelly feeding to described radiating element.
Compared with prior art, the utility model has the advantage of: under the premise keeping antenna size to be basically unchanged, it is achieved the radiances such as high front and back ratio, high cross polarization detectability, wave beam convergence, there is the good circuit performances such as high-isolation simultaneously. This utility model simple in construction, be easily assembled to, stable performance, cost is relatively low.

Detailed description of the invention
In conjunction with the accompanying drawings and embodiments detailed description of the invention of the present utility model is explained as follows:
Fig. 1 is the three-dimensional exemplary plot of one preferred embodiment of this utility model, and wherein 1 is M type metallic reflection plate, and 2 is radiating element, and what radiating element 2 adopted is dual-polarized symmetrical dipole, and oscillator is arranged in the front 1a of reflecting plate 1 by equidistant mode. Namely the direction of oscillator arrangement is the longitudinal direction of metallic reflection plate, and the longitudinal size of reflecting plate is relevant to the quantity of oscillator. 3 is the metal baffle placed between adjacent radiation unit, more specifically, metal baffle 3 is generally positioned at the centre position of adjacent radiation unit. 4 metal strip 4 being located in radiating element both sides, metal strip 4 is parallel with radiating element orientation, and its longitudinal length is relevant with the quantity of oscillator.
Fig. 2 is the cross sectional representation of embodiment in Fig. 1, right angle, reflecting plate 1 both sides flange 11a is (i.e. the front 1a of orienting reflex plate) upward, flange 11a top edge bends after extending certain distance 12a towards the direction away from oscillator more vertically downward, form flange 13a, the height that flange 13a the downwardly extends height more than flange 11a. The width of metal strip 4 is 41a, and the metal strip 4 height apart from reflecting plate bottom surface is 42a, and the distance of metal strip 4 and reflecting plate flange 11a is 43a. Metal baffle 3 is the structure of a notch cuttype, and the width 31a of metal baffle downstairs part is relevant with the width 14a of reflecting plate 1, height 32a and the metal strip 4 height 42a apart from reflecting plate bottom surface relevant (32a is less than 42a); In metal baffle, the width 33a of stepped portion is relevant with the distance 43a of reflecting plate flange 11a with metal strip 4, and height 34a is be more than or equal to the width 41a of metal strip. By suitably optimizing the size of reflecting plate 1, and the positions and dimensions of metal baffle 3, metal strip 4, day radiation at the alignment reflecting plate back side can be reduced on the one hand, the parasitic radiation ripple that metal baffle 3 and metal strip 4 produce simultaneously balances out reflecting plate partial radiation ripple dorsad in space, thus reaching to improve the purpose of front and back ratio; On the other hand, multiple reflecting boundary can regulate the radiation characteristic of antenna, can not only effectively improve cross polarization discrimination index, it is also possible to makes the horizontal beam width of antenna have good concordance in working frequency range.
Fig. 3 is the detail view that metal baffle 3 is connected with reflecting plate 1, metal strip 4 respectively.
According to the antenna for base station of embodiment design in Fig. 1, the horizontal plane of its actual measurement is main polarization with Cross polarization pattern as shown in Figure 4, from fig. 4, it can be seen that front and back reach more than 30dB than index, 0 �� of cross polarization discrimination index is better than 20dB, and positive and negative 60 �� of cross polarization discrimination indexs are better than 14dB.
M type reflecting plate antenna for base station disclosed in the utility model, under the premise that reflecting plate is smaller, not only front and back are better than index, and ensure that good cross polarization discrimination index and horizontal plane beam angle concordance, other every radiation characteristic indexs and circuit performance index are satisfied by instructions for use in addition.
Describing preferred embodiment of the present utility model above by reference to accompanying drawing, those skilled in the art are without departing from scope and spirit of the present utility model, it is possible to have multiple flexible program to realize this utility model. For example, the feature as the shown partially of an embodiment or description can be used for another embodiment to obtain another embodiment. These are only the embodiment that this utility model is preferably feasible, not thereby limit to interest field of the present utility model that the equivalence change that all utilization this utility model description and accompanying drawing content are made is both contained within interest field of the present utility model.
