Description
Technical field
The present invention relates to a kind of antenna applied to satellite reception end, specifically a kind of four-arm spiral antennas.
Background technique
GPS antenna or dipper system on current market, the positioning antenna structure of ordinary antennas receiving end are all using non-
Four wall spiral ways only make antenna carrier using monopole wire or a wires coiled, for reception gain
It is relatively low, it can not achieve dextrorotation member pole, also fail to realize omni-directional antenna, cause antenna entirety reception ability less desirable.
Summary of the invention
The purpose of the present invention is to provide a kind of omni-directionals for being able to achieve antenna and the reception function of dextrorotation member pole, Bu Huishou
The four-arm spiral antenna of directionality limitation, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of four-arm spiral antenna, including TNC connector, PCBA, the first metallic support, metal deck, dead ring, straight gold
Belong to line, insulation glue stick, spiral metal wire, line plate PCBA and the second metallic support, the periphery of the insulation glue stick offers four
Discrete spiral groove, a spiral metal wire is equipped in each spiral groove, and one end of the spiral metal wire is logical
Line plate PCBA to be crossed to fix, the other end of spiral metal wire is connected to PCBA by the first metallic support and the second metallic support, and four
A spiral metal wire is fixed by dead ring；The insulation glue stick is hollow glue stick, and hollow parts are provided with straight metal wire, directly
Metal wire is connected to PCBA by metal deck and runs through dead ring；The other end of the PCBA is connected with TNC connector.
As a further solution of the present invention: for fixing spiral shell there are four being along the circumferential direction uniformly arranged on the dead ring
The groove of wire is revolved, so that independent mutually between four spiral metal wires be connected without short circuit.
Compared with prior art, the beneficial effects of the present invention are: the invention discloses a kind of completely new antenna structures, mainly
Applied to satellite reception end antenna, such as satellite phone, satellite signal receiving base station and three proofings mobile phone, production is simple, performance is stable,
It is low in cost, be suitble to large batch of production；Using four wall spiral metal wire structures, centre is using insulation glue stick, and insulate glue stick
In hollow, at center installation one one metal wire connection insulation glue stick both ends PCBA, insulation glue stick surface is opened with four at center
Discrete spiral groove installs four spiral metal wires in groove and connects the PCBA at both ends, and reception is functional, than
The gain of ordinary antennas will also be higher by 3DB；It is able to achieve the omni-directional of antenna and the reception function of dextrorotation member pole, it will not be by directionality
Limitation, the performance of antenna obtained further optimization and promoted, and belongs to omni-directional satellite reception antenna；It solves satellite to connect
Receiving end antenna is unable to the problem of limitation of omni-directional, realizes dextrorotation member pole, reception energy higher for satellite-signal reception gain
Power is stronger.
Detailed description of the invention
Fig. 1 is explosive view of the invention.
Fig. 2 is main view of the invention.
Wherein, 1-TNC connector；2-PCBA；The first metallic support of 3-；4- metal deck；5- dead ring；The straight metal of 6-
Line；7- insulation glue stick；8- spiral metal wire；9- line plate PCBA；The second metallic support of 10-.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
A kind of four-arm spiral antenna referring to FIG. 1-2, including TNC connector 1, PCBA 2, the first metallic support 3, metal
Deck 4, dead ring 5, straight metal wire 6, insulation glue stick 7, spiral metal wire 8, line plate PCBA 9 and the second metallic support 10, it is described
The periphery of insulation glue stick 7 offers four discrete spiral grooves, and a spiral metal is equipped in each spiral groove
One end of silk 8, the spiral metal wire 8 is fixed by line plate PCBA 9, and the other end of spiral metal wire 8 passes through the first metal branch
Frame 3 and the second metallic support 10 are connected to PCBA, and four spiral metal wires 8 are fixed by dead ring 5, and four spiral metals
It is independent mutually between silk 8 to be connected without short circuit；The insulation glue stick 7 is hollow glue stick, and hollow parts are provided with straight metal wire
6, straight metal wire 6 is connected to PCBA 2 by metal deck 4 and runs through dead ring 5；The other end of the PCBA 2 is connected with TNC
Connector 1.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
Various changes can be made.
