Specific embodiment
Present embodiment discloses a kind of helical antenna of loaded medium lens, as depicted in figs. 1 and 2, including it is exhausted
The bottom plate 1 of edge, the lower surface of bottom plate 1 are equipped with metal layer, and the upper surface of bottom plate 1 is equipped with di-lens 2, sets inside di-lens 2
There is chamber, metal mainstay 6 is equipped in chamber, the upper surface that metal mainstay 6 passes through bottom plate 1 is connected to the lower surface of bottom plate 1, helical antenna
It further include that 8, two metal patches 3 of antenna house and the intracavitary spiral metal patch 5 set on di-lens 2, antenna house 8 pass through spiral shell
Line is fixed on bottom plate 1, is not electrically connected between spiral metal patch 5 and metal mainstay 6, and spiral metal patch 5 is also connected with feedback
Electric structure.One end of metal patch 3 is set on 8 inner wall of antenna house, and the other end of metal patch 3 is hanging.Two metal patches 3 close
In the substantially symmetrical about its central axis of helical antenna.Spiral metal patch 5 connect with bottom plate 1 but not through bottom plate 1, therefore spiral metal patch
5 do not connect with the metal layer of 1 lower surface of bottom plate.
" not being electrically connected between spiral metal patch 5 and metal mainstay 6 " can be realized by kinds of schemes, such as: it can be with
Directly spiral metal patch 5 and metal mainstay 6 are spaced a distance, insulation can also be equipped on the outer wall of metal mainstay 6
Layer 56, spiral metal patch 5 are fixed on insulating layer 56.Insulating layer 56 can be froth bed.
The shape of chamber inside di-lens 2 is cylinder, offers circular groove 21 on the outer wall of di-lens 2,
As shown in Figure 1.
In addition, helical antenna further includes another insulating layer (not being same with insulating layer 56), the connection of insulating layer bottom
The inner wall of the upper surface of bottom plate 1, di-lens 2 attaches on the insulating layer.
Feed structure includes the PCB dieelctric sheet 7 on metal layer, as shown in figure 3, PCB dieelctric sheet 7 is equipped with micro-strip
Line, microstrip line are used to connect external SMP coaxial fitting 4.
Bottom plate 1 diameter 32mm, antenna whole height 12.9mm, PCB dieelctric sheet 7 is situated between using Rogers RT/duroid5880
Lumber, permittivity ε _ γ=2.2, loss tangent angle σ=0.0009 tan, thickness H=0.254mm.Di-lens 2 is arranged
In the limited semielliptical space of short axle a long 12.9mm high, long axial length 32mm.In view of the frequency range of the helical antenna
And wave cover requirement, the lens have chosen the medium of permittivity ε _ γ=6.15, loss tangent angle σ=0.0009 tan
To make.Lens integrally use half concave lens shape, and radian has carried out segmentation adjustment, to guarantee to possess in entire broadband
Good performance.Lens thickness adjusted is with a thickness of 1.5mm, thinnest part thickness 0.2mm, integral diameter 23mm, height
5.5mm.The cross sectional shape of circular groove 21 is arc-shaped, the size of circular section are as follows: radius 3mm, 145 ° of radian.Two
Metal patch 3 is etched by the soft base dielectric-slab of single side, length 6mm, width 2mm.
Fig. 4 is the E-plane and H-plane pattern that helical antenna works in 15GHz, and wherein solid line 1 is non-loaded medium lens
When antenna radiation pattern, dotted line 2 be loaded medium lens after antenna radiation pattern.As seen from the figure, when non-loaded lenses day now-
Beam angle at 5dB is about ± 70 °, and there are 10 ° of recess for central part.After loaded medium lens, the wave beam of antenna is wide
Degree is more than ± 90 °, and central part recess reduces.It can be seen that di-lens has apparent improve to imitate the beam angle of antenna
Fruit.
