Detailed Description
The present application is described in further detail below by way of specific examples and figures. The following examples are merely illustrative of the present application and should not be construed as limiting the present application.
Examples
The novel vibrator of this example, as shown in fig. 1 to 4, is formed by connecting four folded vibrator arms 11, 12, 13 and 14 with the same size end to form an integrally formed folded vibrator, the geometric center of the folded vibrator is provided with a vibrator support 15, the vibrator support is internally provided with feed holes corresponding to each folded vibrator arm, the four feed holes 21, 22, 23 and 24 are distributed in a square shape, wherein the aperture of two adjacent feed holes is larger than that of the other two adjacent feed holes, and an asymmetric feed structure is formed, for example, the first group of feed holes 21 and 22 is different from the second group of feed holes 23 and 24, and the aperture sizes of the two groups of feed holes are different, namely the asymmetric folded vibrator of this example. The folded vibrator and the vibrator support post of this example are integrally formed.
Wherein the folded vibrator arm is in a T shape, two ends of a part of the T-shaped folded vibrator arm extend downwards, and the extension part 16 and the I part 17 form a bandwidth adjusting groove 18; the two ends of the "one" part of the "T" shaped folded dipole arm extending downwards, i.e. the extension part 16 has a hollowed pattern 19, which in this example is heart-shaped.
The folded vibrator of this example has a plurality of cylindrical metal adjusting posts 3 extending vertically upwards along the surface. The metal adjusting column 3 is used for adjusting the center frequency, adjusting the bandwidth and reducing the lobe width and acts as a director.
The folded oscillators of this example are assembled into an array antenna according to a conventional assembly method to test isolation and return loss, and the array antenna is shown in fig. 5 to 7 and comprises a reflecting plate 2 and a plurality of folded oscillators 1 mounted on the reflecting plate 2.
Isolation tests were performed on the asymmetric folded dipole of this example using an Agilent E5071C network analyzer, and the results are shown in FIG. 8. The results of FIG. 8 show that the isolation is better than-32 dB in the 1690-2690MHz frequency band by adopting the asymmetric folded dipole of the example, thereby meeting the requirement of array design. The return loss test of the asymmetric folded dipole in this example shows that the result is shown in fig. 9, and the result in fig. 9 shows that the return loss of both ports is-20 dB, so that the expected design effect can be achieved.
The antenna of this example was subjected to outdoor far field testing to test the horizontal plane pattern of a single element, and the results are shown in fig. 10 and table 1, showing that the beam width of the element of this example is about 57-67 degrees.
Table 1 results of horizontal plane lobe width test for each frequency bin
| Frequency point (MHz) | Lobe width (degree) | Frequency point (MHz) | Lobe width (degree) |
| 1710 | 67.0 | 2300 | 63.0 |
| 1800 | 65.7 | 2400 | 63.1 |
| 1900 | 66.3 | 2500 | 61.7 |
| 2000 | 65.2 | 2600 | 58.9 |
| 2100 | 63.8 | 2690 | 57.6 |
| 2180 | 63.1 | / | / |
The antenna of this example was subjected to outdoor far field testing to test the cross polarization pattern of a single element, and the results are shown in fig. 11, which shows that the cross polarization at plus or minus 60 degrees is better than-15 dB.
Meanwhile, in this example, as a comparison, a traditional symmetrical folded dipole, that is, four feeding holes are the same in size, and other conditions are the same as those of the folded dipole in this example, and an agilent E5071C network analyzer is also used for isolation test, and the result is shown in fig. 12. The results of fig. 12 show that dipoles with the same size of the four feed holes have isolation of only-22 dB in the 1690-2690MHz frequency band, and cannot meet the requirement of array design.
The comparison test and the result show that the asymmetric folded oscillators with different sizes of the four feed holes in the embodiment have higher isolation, so that the communication quality and the capacity can be effectively improved, and the problem of communication quality and capacity reduction of a coupling feed mode is further solved.
The foregoing is a further detailed description of the present application in connection with the specific embodiments, and it is not intended that the practice of the present application be limited to such descriptions. It should be understood that those skilled in the art to which the present application pertains may make several simple deductions or substitutions without departing from the spirit of the present application, and all such deductions or substitutions should be considered to be within the scope of the present application.
