Description
Technical field
The present invention relates to field of radio frequency, more particularly to a kind of 5G ultra-wideband antennas for radome.
Background technology
In November, 2017, Ministry of Industry and Information formally made an announcement, it is determined that China 5G（5th third-generation mobile communication）Frequency, also
It is the working frequency range of 5G, is 3300MHz-3600MHz and 4800MHz-5000MHz.The peak rate of 5G can reach 20Gbps,
It is 20 times of 4G.To meet 5G ultrahigh peak speed, requirements at the higher level are proposed to antenna and spectral bandwidth.
Current existing radome does not support 5G frequency ranges also substantially, general to shield device individual antenna bandwidth 200-
300MHz, for device etc. of being scouted and practised fraud based on 5G wireless signals, there are the neutral gear phase.5G communications bands are more, with wide, and it is existing
Radome, one side bulky, if being further added by 5G frequency ranges needs to increase mutiple antennas, space does not allow.The opposing party
The existing radome in face, is often required for more than ten antennas of installation, and internal electromagnetic environment is complicated, and isolation between antennas is poor.
The content of the invention
The present invention seeks to：A kind of 5G ultra-wideband antennas for radome are provided, are not increasing shielding body product
In the case of, support of the radome to 5G is solved, and isolation is good, adapts to the electromagnetic environment of complexity.
The technical scheme is that：
A kind of 5G ultra-wideband antennas for radome, including pcb board, are provided with exciting unit and spoke on the pcb board
Penetrate unit；The mainboard of radome connects antenna, the cored wire connection exciting unit of the coaxial feeder, screen by coaxial feeder
Cover layer connection radiating element, radiating element ground connection；The exciting unit is the grading profile that one end is narrow, the other end is wide, increases day
Tape is wide, and the beamwidth of antenna covers 5G working frequency range.
Preferably, the exciting unit is triangle, and the cored wire of coaxial feeder is connected to vertex of a triangle.
Preferably, the exciting unit is semicircle, and the cored wire of coaxial feeder is connected to the vertex of circumference.
Preferably, the frequency range of the beamwidth of antenna reaches 2GHz~12GHz.
Preferably, the pcb board of the 5G ultra-wideband antennas is fixed on radome by screw or structure buckle
In shell.
It is an advantage of the invention that：
1. the 5G ultra-wideband antennas for radome of the present invention, using the exciting unit of grading profile, increase aerial band
Width, covers 5G working frequency range, the non-constant width of bandwidth, and frequency range can be very good to support subsequently to lead to 5G more than 2GHz~12GHz
The extension of letter；
2. existing general radome individual antenna bandwidth 200-300MHz, the present invention need not be as existing wireless screen
Cover device and more than ten antennas are installed, support of the radome to 5G is solved under conditions of radome volume is not increased, is carried
High aerial integration ability, shielding body product can be substantially reduced by reducing antenna number, reach small form factor requirements, while can also
Reduce shielding device cost；
3. the peripheral ground of radiating element connection radome of the present invention, isolation is good, adapts to the electromagnetic environment of complexity.
