Technical field
The utility model relates to antenna technology, particularly can optimize directional diagram and promote a kind of antenna assembly of front and back ratio and a kind of radio communication device of applying this antenna assembly.
Background technology
Along with the development of wireless communication technology, the transmission rate of cordless communication network significantly promotes, and the services such as data acquisition, video monitoring are used widely in fields such as electric power, water conservancy, agriculturals, and have obtained good society and economic benefit.
For the each side demand that the Seamless Network of realizing specific region covers and takes into account the network optimization, the sector networking is a kind of top-priority networking mode.As the key of sector networking, the directional antenna of selecting need to meet some crucial index requests, especially at directional diagram and front and back, than aspects such as (front-to-rear ratio), need to consider emphatically.
Specifically:
In order to reduce the interference of sector-edge, certain requirement need to be proposed the directional diagram of directional antenna, to meet the demand of sector networking on some critical angle, for example, power on ° direction of horizontal plane ± 60 descends and maintains the 10dB left and right, and the power on ° direction of horizontal plane ± 90 descends and maintains the 20dB left and right;
And, for some high-order modulating (such as 64QAM), need at least to surpass between homogenous frequency signal the isolation of 25dB, now, the front and back of directional antenna are than just being greater than 25dB.
But the sector networking for some low frequency (scope covers 200MHz～300MHz), the directional antenna used is generally Yagi antenna (also referred to as " Directional Antenna " or " Uda antenna "), but the directional diagram of at present common Yagi antenna is difficult to meet the sector networking, in critical angle, the requirement of power decline and its front and back ratio generally also is merely able to reach the 15dB left and right.
Visible, Yagi antenna is not enough and front and back are higher than not because the power in critical angle descends, thereby can't meet the directed requirement of sector networking.
The utility model content
In view of this, the utility model provides and can optimize directional diagram and promote a kind of antenna assembly of front and back ratio and a kind of radio communication device of applying this antenna assembly.
A kind of antenna assembly that the utility model provides, the directional antenna of an antenna mounting panel of vertically placing, a horizontal positioned and two reflecting plates of vertically placing, wherein:
The end that the root of described directional antenna is fixed in described antenna mounting panel, described directional antenna is suspended at the front portion of described antenna mounting panel;
Two described reflecting plates are installed in respectively described antenna mounting panel in the both sides of described directional antenna, and two described reflecting plates are the angle of predetermined angular in the front portion of described antenna mounting panel.
Two described reflecting plates with respect to described directional antenna, be arranged symmetrically with and the area of two formed reflectings surface of described reflecting plate identical.
Described directional antenna is Yagi antenna.
A kind of radio communication device that the utility model provides, comprise antenna assembly as above.
As can be seen here, the utility model for example, is equiped with reflecting plate in the both sides of directional antenna (Yagi antenna), because reflecting plate can form the angle of predetermined angular from the root of directional antenna in the both sides of directional antenna, therefore, utilize the formed angle of reflecting plate can improve directional antenna and descend at the power of critical angle, to meet the requirement that the sector networking descends to power in critical angle the interference that reduces sector-edge; And, because reflecting plate can be implemented inhibition to a certain degree to the back lobe of directional antenna at the root of directional antenna, therefore, utilize reflecting plate can promote the front and back ratio of directional antenna, with meet the sector networking to the requirement of front and back ratio, and be applicable to the transfer of data that the sector networking adopts high-order modulating.
The accompanying drawing explanation
The structural representation that Fig. 1 a and Fig. 1 b are the antenna assembly in the utility model embodiment;
Fig. 2 is that antenna assembly in the utility model embodiment and the directional diagram of existing antenna assembly are compared schematic diagram.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
Referring to Fig. 1 a and Fig. 1 b, the antenna assembly that the present embodiment provides comprises Yagi antenna 20 and two reflecting plates 30 of vertically placing of an antenna mounting panel 10 of vertically placing, a horizontal positioned, wherein:
The end 20b that the root 20a of Yagi antenna 20 is fixed in antenna mounting panel 10, Yagi antenna 20 is suspended at the front portion of antenna mounting panel 10;
Two reflecting plates 30 are installed in antenna mounting panel 10 in the both sides of Yagi antenna 20 respectively, and two reflecting plates 30 are the angle of predetermined angular in the front portion of antenna mounting panel 10.
As above visible, the utility model has been set up reflecting plate 30 in the both sides of Yagi antenna 20, wherein:
Because two reflecting plates 30 can form the angle of predetermined angular from the root 20a of Yagi antenna 20 in the both sides of Yagi antenna 20, therefore, utilize two formed angles of reflecting plate 30 can improve Yagi antenna 20 and descend at the power of critical angle, to meet the requirement that the sector networking descends to power in critical angle the interference that reduces sector-edge;
Because two reflecting plates 30 can be realized inhibition to a certain degree to the back lobe of Yagi antenna 20 at the root 20a of Yagi antenna 20, therefore, utilize the inhibition of 30 pairs of back lobes of two reflecting plates can promote the front and back ratio of Yagi antenna, with meet the sector networking to the requirement of front and back ratio, and be applicable to the transfer of data that the sector networking adopts high-order modulating.
Provided the directional diagram of Yagi antenna 20 in the 230MHz frequency range in Fig. 2, in the directional diagram shown in Fig. 2, dashed curve means that the power decline of Yagi antenna 20 when not installing reflecting plate 30 changes, and block curve means that the power decline of Yagi antenna 20 when being equiped with reflecting plate 30 changes.
Dashed curve in Fig. 2 and block curve comparison can be found out:
Than the situation of not installing reflecting plate 30, when being equiped with reflecting plate 30, Yagi antenna 20 descends more obvious at the power of each angle;
Than the situation of not installing reflecting plate 30, when being equiped with reflecting plate 30, near the gain of Yagi antenna 20 ± 180 ° is lower, can conclude that thus Yagi antenna 20 front and back now are than higher.
It should be noted that, the present embodiment is with two reflecting plates 30, with respect to Yagi antenna 20, to be arranged symmetrically with and the area of two reflecting plate 30 formed reflectings surface is all example mutually, but, in practical application, those skilled in the art also can adjust as required and arbitrarily.
It is more than the detailed description to the antenna assembly in the present embodiment.Except above-mentioned antenna assembly, the present embodiment also provides a kind of radio communication device of this antenna assembly of application, and this radio communication device comprises antenna assembly as above.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
