Description
Technical field
The utility model is related to wireless telecom equipment technical fields, especially a kind of to be used for mobile communication, wireless local
The signals such as net, short-range data exchange send and receive and receive star positioning antenna.
Background technology
With modern vehicle, ship electronic science and technology high speed development, the rise of especially 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 constantly improves, and needs 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 50mm or more, 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 defect of such antenna element is：There are specific requirement for height, shark fins shell for protrusion outside vehicle in national standard
Height cannot be more than 70mm, therefore the mobile communication antenna being incorporated into shark fins shell height need it is lower, could allow in this way
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, no DC earthing that need to place fulgurite in signal output end to inhibit the transient state electricity of lightning induction
Pressure not only increases cost, but also there is electric discharge tube failure may.
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 problems in space in shark fins shell.
Invention content
The purpose of this utility model be exactly to solve the deficiency of the prior art and a kind of GNSS for providing with LTE collection all day long
Line can meet mobile communication (2G, 3G, 4G mobile communication), WLAN (such as WLAN and WIFI), short distance with an antenna
Data exchange (such as Bluetooth) is independent or the use of frequency range used；It can realize the impedance of antenna feed point and short dot
Match, and then spread bandwidth, reduce certain height, concedes space in shark fins shell；Meet lightning protected requirement simultaneously, reduce at
This.
The utility model is to realize above-mentioned purpose using following technical solution：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, wideband PIFA
Metal arm is arranged at the lower part of oscillator, and for being connect with bottom plate, ceramic antenna is simultaneously welded in bottom plate, and connects with the electrical of coaxial cable
It connects；The center conductor of coaxial cable is welded on wideband PIFA oscillators, and coaxial cable outer conductor is welded on bottom plate, coaxial cable
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, be used for radio signal reception.
Further, antenna cover includes pedestal and case, and screw hole is provided on bottom plate, is connect admittedly with pedestal 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.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：
The utility model is using mainly by coaxial cable, the wideband PIFA oscillators in antenna cover, ceramic antenna, bottom
Metal arm is arranged at the antenna structure that plate is constituted, the lower part of wideband PIFA oscillators, and for being connect 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, outside coaxial cable
Conductor is welded on bottom plate, and coaxial cable is connected to the mobile terminal device of rear end, compact-sized, reliably, makes assembly simply,
It is easy to produce, the advantages that low profile, broadband, DC earthing.
