Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these figure.
The structure chart of the grapefruit satellite antenna that a kind of Ka/Ku that Fig. 1 provides for the utility model one embodiment is coplanar;
A kind of feed structure figure receiving Ku frequency band signals that Fig. 2 provides for the utility model one embodiment;
A kind of feed structure figure receiving Ka frequency band signals that Fig. 3 provides for the utility model one embodiment.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
Fig. 1 shows the structure chart of the coplanar grapefruit satellite antenna of a kind of Ka/Ku that the utility model one embodiment provides, comprising: feed mechanism, the first connector 9 and reflecting surface 2;
Described feed mechanism is by the removable center being sheathed on described reflecting surface 2 of described first connector 9.
The grapefruit satellite antenna of the present embodiment, by changing feed mechanism, can realize the transmitting-receiving of Ka and Ku frequency band signals, and change efficient and convenient, greatly save purchase cost simultaneously.
As the preferred version of the present embodiment, be illustrated in figure 2 the feed structure figure receiving Ku frequency band signals, described feed mechanism comprises Feed Horn 101, frequency reducing low noise amplifier (LowNoiseBlock, LNB) 103, orthogonal film coupler 105, polarized rotation indicating mechanism 106, raising frequency power amplifier (BlockUp-Converter, BUC) 107 and feed bracket 108, described Feed Horn 101, described frequency reducing low noise amplifier 103, described orthogonal film coupler 105, described polarized rotation indicating mechanism 106 and described raising frequency power amplifier 107 are all arranged on described feed bracket 108.
Feed bracket 108 for installing all relevant devices so that can overall quick-replaceable in Renewal process; Polarized rotation indicating mechanism 106 is transducer, for detecting the current angle of pitch of satellite, azimuth and polarizing angle, to reach optimal communication effect according to the theoretical angle of pitch, azimuth and polarizing angle adjustment aerial angle.
The high-frequency signal that Feed Horn 101 receives is converted to intermediate-freuqncy signal by frequency reducing low noise amplifier 103; Described intermediate-freuqncy signal realizes the separation of two-way polarization information by orthogonal film coupler 105, and a road information is used for tracking satellite, and another road information is used for communication; Raising frequency power amplifier 7 is sent to Feed Horn 101 after the intermediate-freuqncy signal of communication is converted to high-frequency signal.
Further, also comprise resistance and send out filter 104, described resistance is sent out filter 104 and is arranged on described feed bracket 108.Resistance is sent out filter and is used for isolating the signal of the signal received and transmission, influences each other to avoid two paths of signals.
Particularly, described feed bracket 108 is connected with pitching transmission platform by the second connector; Described raising frequency power amplifier 107 is connected with driving cabin by the first connecting line; Described frequency reducing low noise amplifier 103 is connected with driving cabin by the second connecting line.
Feed bracket only with pitching transmission platform generation assembly relation, and to be locked by connector, and with control cabinet, drive cabin and mounting not to produce assembly relation.First unclamp the connecting line driving cabin to BUC and LNB during replacing, then pull down feed carriage lock clamping joint, thus realize the replacing of a whole set of feed mechanism, this work generally can complete in 10 minutes.
For example, described first connector is flange; Described second connector is screw; Described first connecting line and described second connecting line are feeder line.
Fig. 3 shows the feed structure figure of the reception Ka frequency band signals that another embodiment provides, and the present embodiment is different from the feed structure that above-described embodiment adopts, and other structure is all identical.Described feed mechanism comprises Feed Horn 201, circular polarizer 210, frequency reducing low noise amplifier 203, orthogonal film coupler 205, raising frequency power amplifier 207 and feed bracket 208, described circular polarizer 210 is sheathed on described Feed Horn 201, and described Feed Horn 201, described frequency reducing low noise amplifier 203, described orthogonal film coupler 205 and described raising frequency power amplifier 207 are all arranged on described feed bracket 208.
The Feed Horn with circular polarizer during Ka UHF band reception, and the Feed Horn not with circular polarizer during Ku UHF band reception.
The requirement of Portable satellite aerial to product weight and size is comparatively harsh, therefore the scheme of Two bors d's oeuveres feed can not be adopted to solve, therefore adopt fast changeable feed to share the solution of a set of primary reflection surface, both can reduce the purchase cost of user, user Ku and Ka instructions for use can be met again.The program solves two problems, and one is can quick-replaceable feed mechanism, and two is reliable fit that antenna surface and two overlaps feed.
Specifically, when carrying out Ku or Ka frequency range and changing, radio frequency feedder mechanism can be overlapped to this and carry out integral replacing, integral replacing can be carried out to the feed mechanism shown in Fig. 2 and Fig. 3.For realize can the radio frequency feedder mechanism of integral replacing, first all devices and parts being installed in the structural design of antenna is fixed on a bracket, and feed bracket only with pitching transmission platform generation assembly relation, and by screw lock, and with control cabinet, drive cabin and mounting not to produce assembly relation.First unclamp the connection feeder line driving cabin to BUC and LNB during replacing, then pull down feed bracket lock-screw, thus realize the replacing of a whole set of radio frequency feedder mechanism; Realize separately antenna surface and two and overlap the connection of feed upper flange plate, it is crucial that the problem of machining accuracy and manufacturing process, as long as the accurate consistency in control antenna face and the consistency of two adpting flanges, just can realize the object of exchanging very easily.
In specification of the present utility model, describe a large amount of detail.But can understand, embodiment of the present utility model can be put into practice when not having these details.In some instances, be not shown specifically known method, structure and technology, so that not fuzzy understanding of this description.
