Description
Technical field
Message area is the utility model is related to, more particularly to a kind of WIFI dual-band and dual-feeds line omnidirectional antenna.
Background technology
Current WIFI antennas existing on the market, otherwise it is that a dual-band antenna goes out a feeding coaxial lines, on mainboard
Need WIFI low-and high-frequency two paths of signals being combined, it is necessary to increase a combiner, cause cost to increase, and match WIFI
Two frequency ranges of low-and high-frequency, cause to research and develop debugging difficulty and workload increase.It is divided into the antenna of two single-frequency, a day
Line is responsible for high-frequency signal transmitting-receiving, and an antenna is responsible for low frequency signal transmitting-receiving, advantage of this is that for single high frequency or
Low-frequency antenna, debugging is relatively easy, but because antenna amount becomes two, can bring the increase of cost.So in order to solve
Above mentioned problem, it is necessary to a antenna is developed, high-frequency signal can either be received and dispatched, can also receive and dispatch low frequency signal, but also simultaneously
Possess 2 feeding coaxial lines, correspond to high-frequency model and low frequency module on mainboard respectively, it is possible to reduce the combiner on mainboard,
Cost is directly reduced, and also reduces mother board impedance matching and debugging work load simultaneously, is easy to product rapid shaping.It is and general
Double-fed line antenna, face a problem again, be exactly because length it is small, low-and high-frequency antenna distance is near, causes to be mutually coupled shadow
Sound is bigger, and the isolation between low-and high-frequency antenna only has -10dB or so, poor.So we just need to develop a energy
Enough solve the above problems, and isolation is below -20dB between low-and high-frequency antenna, and and gain is higher, horizontal plane omnidirectional
Antenna.
Utility model content
The utility model is to provide a kind of WIFI dual-band and dual-feeds line to solve the technical scheme that above-mentioned technical problem uses
Omnidirectional antenna, wherein, concrete technical scheme is：
Including PCB substrate, the side of the PCB substrate sets high frequency feeding coaxial lines, and the opposite side of the PCB substrate is set
Set low frequency feeding coaxial lines；The side of the high frequency feeding coaxial lines sets high frequency antenna unit, second high frequency antenna unit,
The opposite side of the high frequency feeding coaxial lines sets low-frequency antenna unit grounded part, low-frequency antenna unit radiant section, low frequency
Antenna element couples radiant section.
Above-mentioned WIFI dual-band and dual-feed line omnidirectional antennas, wherein：It is coaxial that the high frequency feeding coaxial lines open up high frequency feed
Part is shelled in line.
The utility model has the advantages that relative to prior art：Meet low-and high-frequency two-band, and low-and high-frequency
Isolation between antenna is very high, and horizontal radiation pattern is omnidirectional, and it is small to take into account size, gain height etc., can use an antenna
The effect of two antennas is realized, reduces the combiner on mainboard, and reduces the matching and debugging workload of mainboard end engineer, is made
Obtaining cost reduces, and increases product core competitiveness.

The core section of feeding coaxial lines 2 welds together；Low-frequency antenna unit couples radiant section 6, this part and low-frequency antenna
Unit radiant section 5 is encouraged by slot-coupled and fed；High frequency antenna unit 7, the core of signal section and high frequency feeding coaxial lines 3
Line part welds together, and the knitted parts of grounded part and high frequency feeding coaxial lines 3 weld together；High frequency feeding coaxial lines
Middle stripping part 31, needs braiding to disconnect, is presented by way of revealing cable to second high frequency antenna unit 8 herein
Electricity；
The length of low-frequency antenna unit is the 1/4 of low frequency wavelength, and the coupling unit length of low-frequency antenna unit is low frequency day
The 1/2 of line unit wavelength, the length of high frequency antenna unit are the 1/4 of high-frequency wavelength, and the distance between high frequency antenna unit is height
The 1/2 of frequency wavelength.
