Description

A kind of satellite communication hand-held antenna
Technical field
The utility model relates to a kind of satellite communication equipment, especially a kind of satellite communication hand-held antenna.
Background technology
At present, satellite communication system can ensure the low speed mobile communication of large territorial scope.Hand-held terminal device is easy to carry because having, volume is little, lightweight, speech and short message transmission are safe and reliable, it is convenient to open, easy to operate, the feature such as stand-by time is long, and obtain extensive concern and fast development.In order to meet the requirements such as complete machine miniaturization, mobility and portability, design a kind of and handheld terminal hand held antenna that match, Miniaturization high-gain, just seem particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of requirement that meets satellite communication hand-held terminal, carries and hand held antenna easy to use.
The technical solution of the utility model is:
A satellite communication hand-held antenna, comprises the director, radiator and the reflector that arrange from top to bottom.Described director, radiator and reflector include four blades that are cross-shaped.Between director and radiator, be provided with director support bar, between radiator and reflector, be provided with radiator support bar; In described radiator support bar, be provided with feeder cable and impedance matching and circular polarization and form circuit.
The root of described director blade, radiator blade and reflector blade is equipped with bracing piece and launches and draws structure in, can make mounted blade fixing or gathering.
It is a kind of fixable hinge that structure is drawn in described expansion in.
When described director, radiator and reflector mounted blade, all have and level between approximately 20 ° of angles sagging.
The blade of described director, radiator and reflector is made by high-elastic alloy material, can bending reinstatement.
Described reflector below is also provided with connector; This connector forms circuit by cable with impedance matching and circular polarization and is connected.
Described antenna also comprises antenna protection sleeve, can work as after blade gathering, is sleeved on outside antenna protection antenna.
The beneficial effects of the utility model:
The utility model is reasonable in design, easy to use, and has high, the good consistency of transmitting-receiving gain and balance, wider gain frequency bandwidth and the characteristic such as be easy to carry, and can be good at meeting the demand of satellite handheld terminal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is directional characteristic schematic diagram of the present utility model.
Fig. 3 is stationary wave characteristic schematic diagram of the present utility model.
Wherein: 1-director blade; 2-director support bar; 3-radiator blade; 4-radiator support bar; 5-reflector blade; 6-feeder cable; 7-impedance matching and circular polarization circuit; 8-connector.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises director, radiator and the reflector arranging from top to bottom.Described director, radiator and reflector include four blades that are cross-shaped.Between director and radiator, be provided with director support bar 2, between radiator and reflector, be provided with radiator support bar 4.In described radiator support bar, be provided with feeder cable 6 and impedance matching and circular polarization and form circuit 7.The root of described director, radiator and reflector blade is equipped with bracing piece, to strengthen the intensity of blade.The root of described blade is also provided with a kind of fixable hinge, can make blade can launch as required and fix or draw in.During described mounted blade, all there is sagging with approximately 20 ° of angles of horizontal plane, thereby improve greatly the axial ratio performance of antenna.Described blade is made by high-elastic alloy material, can bending while encountering barrier, and automatic rebounding after bending, recovers original form.Described reflector below is also provided with connector 8, can be connected on satellite antenna device.This connector 8 forms circuit 7 by cable with impedance matching and circular polarization simultaneously and is connected, to realize the transmission of signal.Described antenna also comprises antenna protection sleeve, can work as after blade gathering, is sleeved on antenna, to protect antenna.
Leading indicator of the present utility model is as follows:
1) antenna weight: be not more than 200g;
2) antenna size: collection: length is not more than 260mm; Launch: be highly not more than 400mm, diameter is not more than 450mm
3) antenna gain: be greater than 7dBi(axial ratio);
4) polarization mode: transmitting-receiving is all right-handed circular polarization;
5) standing-wave ratio: 2:1;
6) axial ratio: 3;
7) input and output impedance: 50 Europe;
8) tracking mode: manually, omnidirectional;
9) 3dB beamwidth: 90 degree.
The maximum axial gain of antenna of the present utility model is about 7.0dB, and through actual test, actual measurement yield value is greater than 7dB, meets index request, 3dB beam area approximately 70 degree, as shown in Figure 2.Its standing-wave ratio at frequency of utilization 350MHz-390 MHz with interior all below 2.0, through actual test after impedance matching, standing-wave ratio measured value is also in 1.5, as shown in Figure 3, meets index request.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
