Detailed Description
In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention is specifically described below with reference to the embodiments and the accompanying drawings.
< example >
Fig. 1 is a schematic diagram of an overall structure of a 5G dual-frequency binary MIMO antenna in an embodiment of the present invention.
As shown in fig. 1, the 5G dual-frequency binary MIMO antenna 100 provided in this embodiment includes: a dielectric plate 1, two dual-frequency monopole radiating elements 2 and 3 and an isolation branch 4.
The dielectric plate 1 is a square FR4 substrate with a length of 50mm, and two triangular chamfers are arranged on the dielectric plate 1 and are arranged at two ends of one diagonal line of the dielectric plate.
The two dual-frequency monopole radiating elements 2 and 3 are F-type monopole antennas, and are mounted on the dielectric plate 1 by welding. The polarization direction of the dual-frequency monopole radiating element 2 faces the left side of the dielectric plate 1, and the polarization direction of the dual-frequency monopole radiating element 3 faces the upper side of the dielectric plate 1.
By the above installation method, the dual-frequency monopole radiating element 2 and the dual-frequency monopole radiating element 3 are fed by asymmetric coplanar feeding (ACS), and the polarization directions are perpendicular to each other.
The two ends of the isolation branch knot 4 are Y-shaped. The isolation branches 4 are installed on the dielectric plate 1 in a welding mode, and the length direction of the isolation branches 4 coincides with the direction of one diagonal line of the dielectric plate 1 and is located between the dual-frequency monopole radiation unit 2 and the dual-frequency monopole radiation unit 3. By adjusting the size and the placement position of the isolation branch 4, particularly the total length of the branch, the isolation of the antenna in the working frequency band can be effectively improved. Therefore, the size of the isolated branches 4 is not limited in this embodiment.
The 5G dual-frequency binary MIMO antenna processes the 5G low and high frequency signals by using 1/4 wavelength radiation of the dual-frequency monopole radiating element. And the polarization direction of the dual-frequency monopole radiation unit 2 is orthogonal to the polarization direction of the dual-frequency monopole radiation unit 3, so that the decoupling between the two dual-frequency monopole radiation units is realized. However, the requirement of practical use cannot be met only by adopting vertical placement, so on the basis, a Y-shaped isolation branch is added between the dual-frequency monopole radiation unit 2 and the dual-frequency monopole radiation unit 3. On one hand, the impedance matching of the antenna unit can be improved, and the frequency band can be widened; on the other hand, the space radiation wave can be coupled to the Y-shaped branches, so that the influence of the space radiation wave on the antenna units is reduced, and the influence among the antenna units is greatly reduced.
Fig. 2 is a simulation diagram of a 5G dual-frequency binary MIMO antenna in an embodiment of the present invention.
From the results of the HFSS simulation shown in FIG. 2, S11< -10Db in the frequency bands of 3.3-3.6GHz and 4.8GHz-5.0GHz required by 5G indicates that the impedance matching of the antenna in the working frequency band is satisfactory. Moreover, it can be seen in the figure that the frequency range satisfied by S11< -10DB at high frequency is much larger than the frequency range (5-6GHz) required by 5G, and the high frequency operating frequency band of WiMAX/WLAN can be covered, so the method has wider utilization value.
Fig. 3 is a schematic diagram of isolation simulation of a 5G dual-frequency binary MIMO antenna according to an embodiment of the present invention.
Fig. 3 shows that the improvement of the isolation degree S12 in the ACS feeding mode by comparing the change with frequency without any decoupling measure and adding an isolation stub in 2GHz-6GHz can clearly show that the isolation degree is greatly improved after the above measures are taken, and high isolation degree between antennas is realized by S12< -20DB in the working frequency band.
Effects and effects of the embodiments
According to the 5G dual-frequency binary MIMO antenna provided by this embodiment, because the antenna has the dielectric plate, two dual-frequency monopole radiation units and the isolation branch, wherein the dual-frequency monopole radiation unit installed on the dielectric plate can generate a low-frequency signal and a high-frequency signal of 5G, meanwhile, the two dual-frequency monopole radiation units adopt an asymmetric coplanar band feeding manner to feed, and the isolation branch can decouple the dual-frequency monopole radiation units, so that mutual influence between the antennas is avoided, and the antenna can be applied to a miniaturized mobile terminal device.
According to the 5G dual-frequency binary MIMO antenna provided by the embodiment, because the asymmetric coplanar strip feeding mode is adopted for feeding, the serial connection or the parallel connection with other microwave devices can be realized without drilling holes on the substrate, and further, the miniaturization of a circuit and the integrity of signals can be realized; moreover, the radiation loss of the CPW is relatively small, and the polarization purity and the working efficiency of the antenna can be improved.
Furthermore, because the polarization directions of the two dual-frequency monopole radiating units are perpendicular to each other, the two dual-frequency monopole radiating units can be decoupled, so that the impedance matching of the antenna unit is improved, the frequency band is widened, and the influence of the space radiation waves on the antenna unit is reduced.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
