Description
Technical field
The utility model is related to field of communication technology more particularly to a kind of wide frequency antennas.
Background technology
Electric current on antenna be standing wave distribution, impedance operator and directional characteristic all with frequency shift, therefore they
Frequency band is all very narrow, and about in an octave, the directional characteristic and impedance operator of antenna do not have the antenna of significant changes that can claim
For broad-band antenna.
For the measurement frequency range of antenna when 300MHz-800MHz, antenna standing wave are less than 2, the radiation directivity of antenna is good.But
It is that this antenna frequencies are relatively low, broader bandwidth, antenna standing wave index is difficult debugging.
Utility model content
The utility model is proposed in view of the above problem of the existing technology, and the utility model provides a kind of radiation side
The wide frequency antenna become better.
The utility model is achieved through the following technical solutions：Wide frequency antenna comprising antenna base, antenna cover,
Antenna, the antenna base are equipped with antenna placing groove, and the antenna placement size is consistent with the antenna size, the antenna
Antenna fairlead is equipped in placing groove, the antenna is fixed in the antenna placing groove by the antenna cover；The antenna
Susceptor surface is equipped with chemical Ni-plating layer.
Preferably, conductive material is equipped between the antenna and antenna base.
Further, the conductive material is conducting foam.
Preferably, the decrement of the conducting foam is 30~50%.
Further, the antenna base is equipped with several mounting holes.
Preferably, the antenna cover surface is equipped with the first chemical Ni-plating layer.
Further, the first conducting foam is equipped between the antenna and antenna cover.
Preferably, it uses and is threadedly coupled between the antenna cover and the antenna base.
Compared with prior art, antenna base is equipped with chemical Ni-plating layer, can effectively enhance the electric conductivity of antenna base,
The contact area for widening antenna PCB effectively improves the gain of antenna；Equipped with conductive sponge and make its decrement reach itself 30~
50%, the electric conductivity of conductive sponge can be played to greatest extent, improve the gain of antenna.Therefore, the antenna of the utility model exists
There is 300MHz-800MHz excellent performance, standing wave to be less than 2.0, and radiation directivity is good, small, and stable testing is reliable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the directions A-A view in Fig. 1.
Specific implementation mode
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of wide frequency antenna comprising antenna base 1, antenna cover 2, antenna, the antenna base are equipped with several
Mounting hole 5, the antenna base are equipped with antenna placing groove, and the antenna placing groove size is consistent with the antenna 3, the day
Antenna fairlead is equipped in line placing groove, the antenna 3 is fixed in the antenna placing groove by the antenna cover 2；It is described
1 surface of antenna base is equipped with chemical Ni-plating layer (not shown).
It should be noted that the chemical Ni-plating layer can be distributed on the outer surface of entire antenna base, the increasing of antenna
Benefit is better apparent；It is contemplated that the factor of cost, is equipped with chemical Ni-plating layer, so that it may to play by the surface of antenna placing groove
Good gain effect.In addition, the antenna includes antenna PCB and antenna leads, the antenna PCB is installed on the antenna and puts
It sets in slot, the antenna leads are connected across antenna fairlead with other circuits.
Conductive material is equipped between the antenna 3 and antenna base 1, the conductive material is conducting foam 6, the conduction
The decrement of foam is 30~50%.
The antenna cover surface is equipped with the first chemical Ni-plating layer, and it is conductive that first is equipped between the antenna and antenna cover
Foam.In addition, first chemical Ni-plating layer is arranged in antenna cover and the antenna contact surface.
It uses and is threadedly coupled between the antenna cover 2 and the antenna base 1, i.e., the described antenna base and the antenna
Cover board is equipped with corresponding threaded hole 4.
Compared with prior art, the antenna base of the utility model is equipped with chemical Ni-plating layer, can effectively enhance antenna
The electric conductivity of pedestal widens the contact area of antenna PCB, effectively improves the gain of antenna；Equipped with conductive sponge and make its decrement
Reach itself 30~50%, the electric conductivity of conductive sponge can be played to greatest extent, improve the gain of antenna.Therefore, this practicality
Novel antenna in 300MHz-800MHz there is excellent performance, standing wave to be less than 2.0, and radiation directivity is good, small, test
It is reliable and stable.
The utility model is not limited to the above embodiment, if the various changes or deformation to the utility model do not take off
Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to comprising these changes and deformation.
