It is 20 times of 4G.To meet 5G ultrahigh peak rates, 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 being based on the scouting of 5G wireless signals and cheating device etc., there are the neutral gear phases.5G communications bands are more, with wide, and it is existing
Radome, one side bulky need to increase mutiple antennas if being further added by 5G frequency ranges, and space does not allow.Another 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.
Utility model content
The utility model aim is：A kind of 5G ultra-wideband antennas for radome are provided, shielding device is not being increased
In the case of volume, support of the radome to 5G is solved, and isolation is good, adapt to complicated electromagnetic environment.
The technical solution of the utility model is：
A kind of 5G ultra-wideband antennas for radome, including pcb board are provided with exciting unit on the pcb board
And radiating element；The mainboard of radome connects antenna by coaxial feeder, and the core wire connection excitation of the coaxial feeder is single
Member, shielded layer connect radiating element, radiating element ground connection；The exciting unit is the grading profile that one end is narrow, the other end is wide, is increased
The beamwidth of antenna, the beamwidth of antenna is added to cover 5G working frequency range.
Preferably, the exciting unit is triangle, and the core wire of coaxial feeder is connected to vertex of a triangle.
Preferably, the exciting unit is semicircle, and the core 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.
The utility model has the advantages that：
1. the 5G ultra-wideband antennas for radome of the utility model are increased using the exciting unit of grading profile
Add the beamwidth of antenna, covers 5G working frequency range, bandwidth is very wide, and frequency range is more than 2GHz~12GHz, after can be very good support
The continuous extension that 5G is communicated；
2. existing general radome individual antenna bandwidth 200-300MHz, the utility model need not be as existing
Radome install more than ten antennas, under conditions of not increasing radome volume solve radome to 5G's
It supports, improves aerial integration ability, shielding body product can be substantially reduced by reducing antenna number, reach small form factor requirements, together
When can also reduce shielding device cost；
3. the utility model radiating element connects the peripheral ground of radome, isolation is good, adapts to complexity
Electromagnetic environment.
