Embodiment two:
In order to be more convenient for understanding the present invention, the present invention is done further below with reference to a specific millimeter wave lens antenna
Explanation.
Shown in Figure 1, millimeter wave lens antenna shown in the figure includes lens 1, pedestal 2, is arranged on the base 2
Micro-strip radiating antenna battle array, plane gap battle array, microstrip feed line battle array.Lens 1 include hemispherical lens portion 11 and saturating along the hemispherical
The cylindrical portion 12 that mirror portion extends, the radius R in hemispherical lens portion 11 is 6mm in this implementations, and cylindrical portion 12 prolongs
The length L stretched is 1.5.mm.Pedestal 2 includes the first pedestal layer 21, the second pedestal layer 22, third base set gradually from top to bottom
Seat layer 23 and the 4th pedestal layer 24；The radius R's of cylindrical base 2 can be equal with the radius R in hemispherical lens portion 11, is also set as
6mm；The upper of the first pedestal layer 21 is arranged in lens 1, and micro-strip radiation is provided between the first pedestal layer 21 and the second pedestal layer 22
Antenna array；Plane gap battle array, third pedestal layer 23 and the 4th pedestal layer are equipped between second pedestal layer 22 and third pedestal layer 23
Microstrip feed line battle array is equipped between 24.It is worth noting that, the plane gap battle array in the present embodiment can pass through an independent shape of component
At can also be directly by being formed on the face that the second pedestal layer 22 and third pedestal layer 23 match.Wherein, the first pedestal layer 21
Equal with the thickness of the 4th pedestal layer 24, the second pedestal layer 22 is equal with the thickness of third pedestal layer 23, and the second pedestal layer 22
With third pedestal layer 23 with a thickness of twice of the first pedestal layer 21 and the thickness of the 4th pedestal layer 24.First pedestal layer 21,
Two pedestal layers 22, third pedestal layer 23 and the 4th pedestal layer 24 can be used identical dielectric material and be made.
In the present embodiment, the energisation mode used is difference excitation；In order to guarantee antenna within the scope of a larger angle
Acquire the adequacy and integrality of signal, it is necessary to keep antenna radiation pattern almost the same in one, top coning angle space internal characteristic,
Simple illustration is carried out to the process for determining radiating element number below with reference to the demand.First to the saturating of single radiating element
Mirror antenna is tentatively emulated, and the yield value of an available element antenna can achieve higher level, with high-gain
Characteristic, but the disadvantage is that the beam angle of antenna is very narrow at this time.So secondly, to include lens axis and vertical with plane gap
Plane be symmetrical centre, add second radiating element in the symmetric position of radiating element, become 2 cell arrays, two ends
Mouth plus constant amplitude reverse energization simultaneously emulate, to keep and improve antenna direction characteristic while reach extension beam angle, further increasing
Add the effect of yield value.The adequacy and integrality of signal are acquired to guarantee antenna within the scope of a larger angle, it is necessary to
Keep antenna radiation pattern almost the same in one, top coning angle space internal characteristic.Therefore, finally, according to same thinking, by two
Unit radiates element array using lens axis as shaft, and 90 ° are rotated clockwise in respective respective planes, becomes 4 cell arrays, phase
Two-port difference is motivated.The distribution map of obtained each array is as shown in Figure 2:
Micro-strip radiating antenna battle array shown in Fig. 2, plane gap battle array, microstrip feed line battle array all include 4 elements.And it can by the figure
Know, 4 plane gaps and microstrip feed line that 4 micro-strip radiating antennas that micro-strip radiating antenna battle array includes, plane gap battle array include
4 microstrip feed lines that battle array includes are distributed in sphere of movements for the elephants in affiliated plane.Wherein, micro-strip radiating antenna 3,4 and of plane gap
Microstrip feed line 5 is both configured to rectangle.In each group, micro-strip radiating antenna 3, plane gap 4 geometric center it is same perpendicular to
On a vertical line on plane gap 4, the geometric center of micro-strip radiating antenna 3, plane gap 4 and microstrip feed line 5 is then same
One perpendicular on a vertical plane on plane gap 4, and micro-strip radiating antenna 3, the length direction of plane gap 4 are parallel, and with
The length direction of microstrip feed line 5 is vertical.In the present embodiment, if the length of micro-strip radiating antenna 3 is 0.5mm, width 0.45mm；
The length of plane gap 4 is 0.8mm, width 0.14mm；The selection of 5 size of microstrip feed line is mainly in terms of its characteristic impedance
Consider, if the length is 2.4mm, width 0.18mm guarantees that its characteristic impedance is 50 ohm.Emulate with the antenna
The result difference arrived is as in Figure 3-5.
Fig. 3 show the return loss performance test chart of lens antenna provided in this embodiment.It is generally defined back in engineering
It is working frequency range that wave loss, which is less than the corresponding frequency range of -10db,.The work of lens antenna provided in this embodiment as seen from Figure 3
Frequency range is 57.491-66.838GHz, covers the free licensed band of entire 57-66GHz substantially.
Fig. 4 and Fig. 5 is lens antenna provided in this embodiment directional diagram at 60GHz.
The directional diagram of lens antenna when Fig. 4 is phi=0 °, the directional diagram of lens antenna when Fig. 5 is phi=90 °.It can be seen that
At phi=0 ° and phi=90 °, the directional diagram of lens antenna is substantially completely identical, shows that lens antenna is flat in a coning angle
Characteristic is almost the same on face.Lens antenna gain is 14.4dbi in Fig. 4 and Fig. 5, and 3db width is 28.8 °, and gain is greater than 10dbi
Beam angle up to 35 °.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to protection of the invention
Range.
