Abstract
The utility model relates to a hand-held terminal antenna of mobile satellite communication. The antenna comprises a shell, an antenna radiation body arranged in the shell, an impedance matching circuit and a circular polarization forming circuit. The antenna radiation body comprises four metal spiral lines which are spiral so as to form a cylinder from bottom to top. Lower ends of the metal spiral lines are connected with the impedance matching circuit and the circular polarization forming circuit through a feed line. The design of the antenna of the utility model is reasonable. The structure is simple and radiation efficiency is high. Installation and usage are convenient and a communication capability of a satellite-communication hand-held terminal can be enhanced. Simultaneously, a working frequency range is wide and a working requirement of two frequency range transmitting and receiving of the satellite communication can be satisfied.
Description
Technical field
The utility model relates to a kind of satellite communication equipment, especially a kind of mobile satellite communication handheld terminal antenna.
Background technology
At present, along with the development of electronic technology, it is further important that the miniaturization of communication system and portability seem, product requirement is done less and less, and performance requirement is more and more higher, and Antenna Design has also been had to higher requirement.For making satellite communication hand-held terminal equipment both guarantee that it was easy to carry, guarantee again the communication performance that it is good, be badly in need of the handheld terminal antenna that a kind of volume of design is little, lightweight, function is strong.
Summary of the invention
The purpose of this utility model is for increasingly extensive mobile satellite communication field, and the handheld terminal that a kind of volume is little, lightweight, function is strong antenna is provided.
The technical solution of the utility model is:
A mobile satellite communication handheld terminal antenna, the antenna radiator, impedance matching circuit and the circular polarization that comprise shell, are placed in shell form circuit.Described antenna radiator comprises four wire spirals, and the cylinder of formation that spirals from bottom to top; The lower end of described wire spiral forms circuit by feeder line with impedance matching circuit and circular polarization and is connected.
The described wire spiral cylindrical diameter forming that spirals is 14mm, is highly 130mm.
The two ends up and down of described shell are respectively equipped with upper cover plate and lower cover.
Described impedance matching circuit and circular polarization form the below that circuit is positioned at lower cover.
The beneficial effects of the utility model:
The utility model is reasonable in design, simple in structure, and radiation efficiency is high, is not only convenient to install and use, and also can strengthen the communication capacity of satellite communication hand-held terminal.Meanwhile, also there is wider working frequency range, can meet the job requirement of two frequency ranges of satellite communication transmitting-receiving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-wire spiral; 2-shell; 3-upper cover plate; 4-lower cover; 5-feeder line; 6-impedance matching circuit; 7-cable; 8-circular polarization forms circuit.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises shell 2, is placed in antenna radiator, impedance matching circuit 6 and circular polarization formation circuit 8 in shell 2.The two ends up and down of described shell 2 are respectively equipped with upper cover plate 3 and lower cover 4.Described antenna radiator comprises four wire spirals 1, and spirals from bottom to top that to form a diameter be 14mm, is highly the cylinder of 130mm.Described wire spiral 1 is encapsulated in described shell and upper and lower cover plates, and its lower end forms circuit 8 with the impedance matching circuit 6 that is positioned at the below of lower cover 4 with circular polarization by feeder line 5 and is connected.
Above-mentioned antenna is arranged at handheld terminal top, and is connected with handheld terminal by cable.The signal of cable transmission forms circuit and impedance matching circuit by circular polarization, is divided into four tunnels, and phase difference is each other 90 °, is respectively 0 °, 90 °, 180 °, 270 °.Every spiral radiation line on antenna is a corresponding road signal respectively, and can produce resonance in transmitting-receiving frequency range, transmits and receives satellite-signal.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
