Description

The KU plate aerial

Technical field

The utility model relates to a kind of antenna, relates in particular to a kind of KU plate aerial.

Background technology

At present, plate aerial is little, easy to carry with its volume, efficient and gain advantage of higher are subjected to using widely, is particularly useful for dealing with accidents such as weather, terror.

In the prior art and since satellite communication at the receiving frequency of Ku frequency range (10-14.5GHz) at 10-12.75GHz, and transmission frequency is at 14-14.5GHz.It is very difficult that such one pair of plate aerial frequency will cover 10-14.5GHz.

There is following shortcoming at least in above-mentioned prior art:

Existing plate aerial technology can only be received satellite-signal, and can not send out simultaneously.

The utility model content

The purpose of this utility model provide a kind of can be to the KU plate aerial of satellite-signal sending and receiving simultaneously.

The purpose of this utility model is achieved through the following technical solutions:

KU plate aerial of the present utility model comprises substrate, and described substrate is arranged in juxtaposition two aerial arrays at grade, and the polarization of described two aerial arrays is vertical mutually.

The technical scheme that is provided by above-mentioned the utility model as can be seen, KU plate aerial described in the utility model, because substrate is arranged in juxtaposition two aerial arrays at grade, the polarization of two aerial arrays is vertical mutually, one of them can be used for received signal, and another can be used to transmit.Can realize satellite-signal sending and receiving simultaneously.

Embodiment

KU plate aerial of the present utility model, the embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4 comprise substrate, and substrate is arranged in juxtaposition two aerial arrays at grade, and the polarization of two aerial arrays is vertical mutually.

This plate aerial comprises three laminar substrates, is respectively radiating layer, conducting shell, feed layer;

As shown in Figure 1 and Figure 2, it is vertical mutually that radiating layer is provided with the direction of

radiator

11,12 of 11,12, two aerial arrays of radiator of two aerial arrays;

As shown in Figure 3, Figure 4, it is vertical mutually that conducting shell and feed layer are provided with the direction of

resonator

21,22 of 21,22, two antennas of resonator of two array antennas.

Specific embodiment:

The length dimension of

radiator

11,12 is E=28.68mm, and width dimensions is F=19.83mm;

The long limit of

resonator

21,22 is of a size of B=15.8mm, and minor face is of a size of A=7.9mm; Step on the long limit of resonator is of a size of C=7.7mm, and the step on the minor face is of a size of D=7.75mm.

The frequency coverage of this plate aerial is 10-14.5GHz.

In the prior art, use the microstrip line base material, when having posted a letter when high-power, microstrip line itself just mutually coupling produce mutually and disturb. microstrip line electromagnetic wave loss simultaneously is big, at the bottom of the efficient, and the satellite plate aerial accomplishes that the high-gain that can satisfy the satellite requirement just can not.In order to satisfy on the equator the requirement of satellite antenna gain, antenna gain should be enough big, because of antenna gain is directly proportional with area.Improve antenna gain and will increase antenna area, and at this moment little band consumption also strengthens thereupon.The result is that the area of antenna has increased, and gain but at the worst.Another shortcoming of killing is that receive-transmit isolation is poor, can interfere with the end of collecting mail when needing high-power emission during satellite communication, causes the collection of letters to use.

In the utility model, by with the resonator half-twist, from newly carrying out permutation and combination, generate the plate aerial of another polarization, in the requirement of basis to antenna gain, by different array combination, design two antennas of horizontal polarization and perpendicular polarization, the plate aerial with two different polarization is combined in the plane then.Synthesize a dual-polarized plate aerial, such plate aerial just can carry out the satellite transmitting-receiving bidirectional and communicate by letter.

Also, can cover KU (10-14.5GHz) frequency range fully by the mutual coupling between size A, B, C, D, E and the F.Satisfy the requirement of satellite to ground sending and receiving letter machine plate aerial.

The utility model is because be two fully independently antennas, though in a plane, but the interface of neither one association, so just do not have the problem of crosstalking mutually, need not add any isolator and adaptation yet, such design had both reduced the complexity of structure, had improved receive-transmit isolation again, had also promoted the stability of equipment.

The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
