As for the above-mentioned metal plating layers, the first metal plating layer 111, the second metal plating layer 112, the third metal plating layer 113 and the fourth metal plating layer 114 are rectangular with equal dimensions and are symmetrical about the center point of the welding surface 11.

The present utility model further provides an embodiment of a circuit board 200, as shown in fig. 3, where the circuit board 200 includes a board body 202 and the antenna 100 described above, and for the structure and function of the antenna 100, reference may be made to the above embodiment, which is not described herein, where the dielectric substrate 1 of the antenna 100 is soldered to the board body, the circuit board 200 includes a feeding network (not labeled), the feeding network is disposed on the board body 202, the feeding network is connected to the dielectric substrate 1, the feeding network includes 50 Ω microstrip lines 201 perpendicular to each other, in this embodiment, the first metal plating 111 and the second metal plating 112 are preferably used as feeding points, the third metal plating 113 and the fourth metal plating 114 are preferably used as soldering points, in this embodiment, one microstrip line 201 and the first metal plating 111 located at the soldering surface 11 form a first feeding point 201a, another microstrip line 201 and the adjacent metal plating 112 located at the soldering surface 11 form a second feeding point 201b, and the third metal plating 113 and the fourth metal plating 114 are soldered to the circuit board 200 together for fixing the antenna 100. The antenna 100 based on the structural design has a simple structural design of the required feed network plate layer, and is convenient for the installation and maintenance of the antenna 100.
For the convenience of the reader to better understand the concepts of the present utility model, an example simulation of antenna 100 is performed below. In the case where the dielectric substrate has a dielectric constant of 9 and a dielectric loss of 0.00054, the optimal dimensions for one set of antennas 100 are:
the length and width of the media substrate 1 are L D and W D, respectively, wherein the length L D is preferably 1.4 mm and the width W D is preferably 1.4 mm;
The height of the dielectric substrate 1 is H D, wherein the height H D is preferably 1.7 mm;
The width of the first metal plating layer 111, the width of the second metal plating layer 112, the width of the third metal plating layer 113, the width of the fourth metal plating layer 114, the width of the fifth metal plating layer 121, the width of the sixth metal 131, the width of the seventh metal plating layer 141, and the width of the eighth metal plating layer 151 are all W M, wherein the width W M is preferably 0.3 mm;
The length of the first metal plating layer 111, the length of the second metal plating layer 112, the length of the third metal plating layer 113, and the length of the fourth metal plating layer 114 are all L M, wherein L M is preferably 0.3 mm;
The height of the fifth metal plating layer 121, the height of the sixth metal plating layer 131, the height of the seventh metal plating layer 141, and the length of the eighth metal plating layer 151 are all heights, wherein the height H M is preferably 0.68 mm.
The S-parameter simulation results are shown in fig. 4 when the optimally sized antenna 100 is placed in the middle of a 10 mm by 10 mm circuit board. Since the antenna 100 is of a symmetrical double feed structure design, the reflection coefficients of the adjacent first and second feeding points 201a and 201b are uniform, and the dielectric antenna 100 is a dual polarized antenna. The reflection coefficient of the antenna 100 is smaller than-7.7 dB, the bandwidth ranges from 37 GHz to 43.02 GHz, the center frequency is 40.01 GHz, the absolute bandwidth is 6.02 GHz, the relative bandwidth is 15.05%, and the wide passband characteristics are provided. The isolation of the two ports is greater than 13.6 dB in the passband, and the high isolation characteristic is achieved.
The radiation pattern simulation results for an optimally sized antenna 100 are shown in fig. 5 and 6. As can be seen from fig. 5 and fig. 6, when one microstrip line 201 of the antenna 100 is fed through the first feeding point 201a and the other microstrip line 201 is fed through the second feeding point 201b, the amplitudes of the radiation directions of the antenna 100 are almost identical, and the maximum gains of the first feeding point 201a and the second feeding point 201b fed individually are about 6.35 dB.
Since the antenna 100 of the present embodiment is symmetrically designed and placed at the center of the circuit board 200, the reflection coefficients of the first feeding point 201a and the second feeding point 201b are uniform. Further, small dimensional changes in the dielectric substrate 1, the first metal plating layer 111, the second metal plating layer 112, the third metal plating layer 113, the fourth metal plating layer 114, the fifth metal plating layer 121, the sixth metal plating layer 131, the seventh metal plating layer 141, and the eighth metal plating layer 151 do not change the resonance mode of the antenna 100, but only cause a shift in the resonance frequency, i.e., the radiation characteristics of the antenna 100 do not change with a change in the value of the parameter under study. Therefore, it is only necessary to pay attention to the reflection coefficient at the first feeding point 201a or the second feeding point 201b and the isolation between the first feeding point 201a and the second feeding point 201b in order to study the influence of the relevant parameters of the antenna 100 on the performance of the antenna 100.
As can be seen from fig. 7, when the dielectric substrate 1 of the antenna 100 is changed only in its length L D or width W D, i.e., the length L D or width W D of the dielectric substrate 1 is increased from 1.2 mm to 1.6 mm, the resonant frequency of the antenna 100 is shifted down from 42.84 GHz to 36.93 GHz. Further, as the parameter length L D or width W D increases, the isolation of the antenna 100 at the resonant frequency becomes greater; when the length L D or the width W D of the dielectric substrate 1 is 1.4 mm, the reflection coefficient of the antenna 100 at the resonance frequency is minimum.
As can be seen from fig. 8, when the dielectric substrate 1 of the antenna 100 is changed only in its height H D, i.e., the height H D of the dielectric substrate 1 is increased from 1.6 mm to 1.8 mm, the resonance frequency thereof is shifted down from 39.91 GHz to 39.39 GHz. In addition, as the 20 height H D of the dielectric base 1 increases, the isolation of the antenna 100 slightly becomes smaller; when the height H D of the dielectric substrate 1 is 1.7 mm, the reflection coefficient of the antenna 100 at the resonance frequency is minimum.
Because the welding surface metal coating is connected with the side surface metal coating, and the width of the welding surface metal coating is consistent with that of the side surface metal coating, the size of any one part of the welding surface metal coating or the welding surface metal coating is changed, and the size of the other corresponding part is also changed. As can be seen from fig. 9, when the width W M of the metal plating of the antenna 100 is changed, i.e., the width of the metal plating W M is increased from 0.2 mm to 0.4 mm, the resonance frequency thereof is shifted down from 40.63 GHz to 39.02 GHz only. In addition, as the metal plating width W M increases, the isolation of the antenna 100 becomes greater; when the metal plating width W M is 0.3 mm, the reflection coefficient of the antenna 100 at the resonance frequency is minimum.
As can be seen from fig. 10, when the soldering surface metallization of the antenna 100 changes its length L M, i.e. the length L M of the soldering surface metallization increases from 0.2 mm to 0.4 mm, its resonance frequency shifts down from 40.41 GHz to 38.95 GHz. In addition, as the length L M of the soldering face metal plating layer increases, the isolation of the antenna 100 at the resonance frequency becomes large; when the length L M of the soldering face metallization is 0.3 mm, the reflection coefficient of the antenna 100 at the resonance frequency is minimal.
As can be seen from fig. 11, when the side metallization of the antenna 100 changes its height H D, i.e., the height H D of the side metallization increases from 0.58 to 0.78 mm, its resonant frequency shifts down from 41.71 GHz to 37.41 GHz. In addition, as the height H D of the side metal plating layer increases, the isolation of the antenna 100 at the resonance frequency becomes large; when the height H D of the side metal plating is 0.68 mm, the reflection coefficient of the antenna 100 at the resonance frequency is minimum.
In the embodiment of the utility model, the antenna 100 comprises a dielectric substrate 1, wherein the dielectric substrate 1 is provided with a welding surface 11, a first side 12, a second side 13, a third side 14 and a fourth side 15; the welding surface 11 is provided with a first metal plating layer 111, a second metal plating layer 112, a third metal plating layer 113 and a fourth metal plating layer 114; the first metal plating layer 111, the second metal plating layer 112, the third metal plating layer 113 and the fourth metal plating layer 114 are respectively positioned at the centers of the four sides of the welding surface 11; the first side 12 is provided with a fifth metal plating layer 121, the second side 13 is provided with a sixth metal plating layer 131, the third side 14 is provided with a seventh metal plating layer 141, and the fourth side 15 is provided with an eighth metal plating layer 151; wherein the first metallization 111 is connected to a fifth metallization 121 on the first side 12, the second metallization 112 is connected to a sixth metallization 131 on the second side 13, the third metallization 113 is connected to a seventh metallization 141 on the third side 14, and the fourth metallization 114 is connected to an eighth metallization 151 on the fourth side 15.
