The invention discloses a kind of GNSS and LTE is antenna integrated, it is characterized in that, it includes coaxial cable, wideband PIFA oscillators, ceramic antenna, bottom plate in antenna cover, metal arm is arranged at the lower part of wideband PIFA oscillators, for being connected with bottom plate, ceramic antenna is simultaneously welded in bottom plate, and the electrical connection with coaxial cable；The center conductor of coaxial cable is welded on wideband PIFA oscillators, and coaxial cable outer conductor is welded on bottom plate.The antenna configuration of " F " type that the present invention uses can realize the impedance matching of antenna feed point and short dot, and then spread bandwidth, reduce certain height, concede space in shark fins shell；Meet lightning protected requirement at the same time, reduce cost.
Description
Technical field
The present invention relates to wireless telecom equipment technical field, particularly one kind can be used for mobile communication, WLAN, short
The signals such as range data exchange are received and sent with receiving star positioning antenna.
Background technology
With the rise of modern vehicle, ship electronic science and technology high speed development, particularly vehicle-mounted Internet technology, shipping vehicle
On incorporate the equipment such as more and more voice and video communications, data exchange, multimedia recreation.Only broadcast listening (AM/FM) and
CD music has been unable to meet the needs of people, mobile communication (such as 2G, 3G, 4G mobile communication), WLAN (such as WLAN and
WIFI), short-range data exchanges (such as Bluetooth) function and has been widely used in vehicle-mounted (ship) electronic field,
Present people's living standard is constantly improved, it is necessary to have higher to voice and video communication, data exchange, multimedia recreation service
Requirement.
By taking mobile communication (2G, 3G, 4G mobile communication) antenna that vehicle uses as an example.The mobile communication being commonly used
Aerial integration is in shark fin-shaped shell, and communication antenna unit uses monopole minor structure, highly in more than 50mm, PCB or metal
Chip antenna oscillator is vertical to be welded on one piece of horizontal PCB, and antenna received signal is output to mobile terminal through coaxial cable
Equipment.The defects of such a antenna element, is：There are clear and definite requirement for height, shark fins shell for protrusion outside vehicle in national standard
Height cannot be more than 70mm, therefore the height for the mobile communication antenna being incorporated into shark fins shell needs lower, could so allow
The antenna for going out space to other frequency ranges uses, and existing antenna is difficult to meet requirements above；Meanwhile the communication day being commonly used
Line mostly uses monopole minor structure, and no DC earthing, need to place fulgurite to suppress the transient state of lightning induction electricity in signal output part
Pressure, not only increases cost, but also it is possible to there is electric discharge tube failure.
In addition, when more antennas need to be integrated into shark fins shell, such as WLAN (such as WLAN and WIFI), short
Range data exchanges (such as Bluetooth) signal transmitting and receiving antenna, and there are the inadequate problem in space in shark fins housing.
The content of the invention
The purpose of the present invention be exactly in order to which a kind of GNSS and LTE for solving the deficiency of the prior art and providing is antenna integrated,
It can meet mobile communication (2G, 3G, 4G mobile communication), WLAN (such as WLAN and WIFI), short distance number with an antenna
According to exchanging, (such as Bluetooth) independent or the use of frequency range used；It can realize the impedance matching of antenna feed point and short dot,
And then spread bandwidth, reduce certain height, concede space in shark fins shell；Meet lightning protected requirement at the same time, reduce cost.
The present invention is to realize above-mentioned purpose using following technical solution：A kind of GNSS and LTE is antenna integrated, it is special
Sign is that it includes coaxial cable, wideband PIFA oscillators, ceramic antenna, bottom plate in antenna cover, wideband PIFA oscillators
Lower part have metal arm, for being connected with bottom plate, ceramic antenna is simultaneously welded in bottom plate, and the electrical connection with coaxial cable；
The center conductor of coaxial cable is welded on wideband PIFA oscillators, and coaxial cable outer conductor is welded on bottom plate, and coaxial cable connects
It is connected to the mobile terminal device of rear end.
As a further illustration of the above scheme, the metal arm has metal backing by the metal materials such as copper, aluminium or surface
PCB be made, for radio signal reception.
Further, antenna cover includes base and case, and screw hole is provided with bottom plate, is connected admittedly with base by screw
It is fixed.
Further, wideband PIFA oscillators are provided with outwardly directed feed arm, and coax cable center conductor is welded on feedback
In electric arm.
It is of the invention to be using the attainable beneficial effect of above-mentioned technical solution institute：
The present invention is using mainly by coaxial cable, wideband PIFA oscillators, ceramic antenna, bottom plate structure in antenna cover
Into antenna structure, metal arm is arranged at the lower part of wideband PIFA oscillators, and for being connected with bottom plate, ceramic antenna is simultaneously welded in bottom plate,
And the electrical connection with coaxial cable；The center conductor of coaxial cable is welded on wideband PIFA oscillators, is led outside coaxial cable
Body is welded on bottom plate, and coaxial cable is connected to the mobile terminal device of rear end, compact-sized, reliably, makes assembling simply, just
In the production, low profile, broadband, DC earthing the advantages that.
