Background technique
Antenna is as the indispensable critical component of wireless telecommunications system, for emitting or receiving radio wave to transmit nothing
Line signal, antenna are the front ends of entire wireless telecom equipment, and the superiority and inferiority of performance plays the performance of whole equipment most important
Effect.
With the rapid development of mobile communication technology, bandwidth broadning is always the direction of terminal antenna development, in 2G, 3G
On the basis of, comprehensive covering is just being done step-by-step in 4G network.In view of the communication protocol used all over the world and divide frequency range not to the utmost
Identical, to realize global roaming, mobile terminal antenna needs support multiband covering；The frequency range of 4G covering has GSM850 (824-
894MHz)、GSM900(880-960MHz)、DCS(1710-1880MHz)、PCS(1850-1990MHz)、UMTS(1920-
2170MHz), LTE2300 (2300-2400MHz), LTE2500(2500-2690MHz).Therefore, the mobile terminal day of 4G is supported
Line generally requires covering 824~960MHz, 1710~2690MHz frequency range.
In order to realize that the above-mentioned 4G frequency range of covering, typical design method are using three-dimensional structure, such as helical antenna, PIFA
Antenna and folded monopole sub-antenna, this kind of antenna have more design freedom, are generally possible to meet frequency range covering requirement, still
Be unfavorable for processing and it is highly integrated, be typically mounted at the outer metallic surface of car body or hull, it is difficult to conformal easy to damage.Paste glass day
Line is mounted on the inner surface of glass, and entire infrastructure is all in the inside of vehicle or ship, high safety and reliability；In order to avoid blocking sight,
It is required that patch glass antenna is small in size, and it is conformal with glass, it requires to contradict with the covering of the multiband of antenna, there is design challenges.
Therefore, the prior art is up for improving and improving.
Summary of the invention
The shortcomings that the purpose of this utility model is to overcome above-mentioned background techniques provides one kind in limited, smaller sky
In, the 4G antenna for meeting bandwidth requirement is designed, ultra wide band, high efficiency wireless transmission capability may be implemented, and keep antenna
The stable structure of device, small in size, installation is simple, cost of manufacture is lower and has a kind of small in size, easy of integration, radiance
It is excellent, and realize covering 824~960MHz, 1710~2690MHz frequency range, and can be realized in working range VSWR <
1.9 wideband plate 4G antenna.
To achieve the above object, the technical scheme adopted by the utility model is
A kind of novel high-gain 4G antenna, including feed point, grounding point, radio frequency line and two-sided PCB high frequency plate, feed point and ground connection
Point is located in two-sided PCB high frequency plate surface, and feed point is connected with the core wire of radio frequency line, and grounding point is connected with the shielded layer of radio frequency line,
Two-sided PCB high frequency plate front is equipped with snakelike cabling, high-frequency wideband cabling, low frequency cabling and radio frequency cabling, radio frequency cabling and snake
It is formed with coupled signal between shape cabling, sets one between radio frequency cabling and high-frequency wideband cabling and couples gap.
Compared with prior art, the utility model has the beneficial effects that
It designs, is motivated by coupling gap due to the above structure, realize the capacitive load of cabling, reduce single
Pole sub-antenna perception is conducive to expand bandwidth, and uses unique racemosus section structure, realizes biggish design remaining, on a large scale
Bandwidth is expanded, realizes multiband covering；The conformal installation requirement of the mounting surface of certain radian can be preferably adapted to, simultaneously
Flexible antennas can also be fabricated to using FPC technique, be mounted on inside non-metal material surface or equipment.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Each label is respectively in figure: (1) feed point, (2) grounding point, (3) radio frequency line, and (4) two-sided PCB high frequency plate, (5) are snakelike
Cabling, (6) high-frequency wideband cabling, (7) low frequency cabling, (8) radio frequency cabling, (9) couple gap.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing referring to Figure 1, and the utility model is a kind of new
Type high-gain 4G antenna, including feed point 1, grounding point 2, radio frequency line 3 and two-sided PCB high frequency plate 4, feed point 1 and grounding point 2 are located at double
In the PCB high frequency plate surface of face, feed point 1 is connected with the core wire of radio frequency line 3, and grounding point 2 is connected with the shielded layer of radio frequency line 3, two-sided
4 front of PCB high frequency plate be equipped with snakelike cabling 5, high-frequency wideband cabling 6, low frequency cabling 7 and radio frequency cabling 8, radio frequency cabling 8 with
It is formed with coupled signal between snakelike cabling 5, one is set between radio frequency cabling 8 and high-frequency wideband cabling 6 and couples gap 9.
