Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a miniaturized vibrator and an antenna. Background Art

[0002] The frequency bands for civil communications are mainly concentrated below sub-6G. The typical frequency band of 1710-2690MHz includes 2G, 3G, 4G and part of 5G, which means that a vibrator can be shared by multiple antennas. In order to save production and assembly costs, the vibrator must have a simple installation method while meeting broadband characteristics and be as small as possible to meet various usage scenarios, such as high and low frequency nesting, and adding a guide plate.

[0003] Most existing vibrators have the problem of being too large in diameter while meeting the broadband characteristics. When installed on the reflector, metal screws or plastic rivets are often used for fixing, which is more complicated to install and increases material costs. Some vibrators were not designed with universality in mind, and there are interference problems when used with low-frequency vibrators, which results in multiple vibrators on one antenna, increasing the complexity of antenna assembly.

[0033] The loading section 220 is disposed at a corner of the bottom of the vibrator arm 100 and is perpendicular to the vibrator surface 200 .

[0034] It should be noted that, in this embodiment, the vibrator surface 200 adopts an arc-shaped hollow structure, and a loading section 220 is added at the end of the vibrator arm 100. These two measures extend the current path of the vibrator arm 100, so that the vibrator 10 has a wider working bandwidth. In order to solve the problem of the vibrator 10 having a large caliber due to the wide bandwidth, the loading section 220 is bent downward and perpendicular to the vibrator surface 200, thereby reducing the caliber of the vibrator 10 and miniaturizing the vibrator 10. By adjusting the tortuous length of the arc-shaped hollow structure and the length of the loading section 220, the caliber of the vibrator 10 can be effectively adjusted, and the shape of the feed core needs to be adjusted to maintain the working bandwidth.

[0035] In some embodiments, there are four loading sections 220 in total, and the four loading sections 220 are disposed at four corners of the vibrator surface 200 .

The first connecting member 510 is fixed on the vibrator arm 100 through the groove. The first connecting member 510 is used to fix the guide plate, thereby ensuring the versatility of the vibrator 10. At the same time, a plurality of slots are provided on the first connecting member 510, which can be used to adjust the height of the guide plate.

[0039] In some embodiments, the first connecting member 510 defines a plurality of first slots 511 along a vertical direction.

[0040] In some embodiments, the first connecting member 510 is made of plastic.

[0047] The conventional vibrator 10 is fixedly installed and locked to the reflector 600 by rivets or screws. The utility model realizes the assembly of the vibrator 10 and the second connecting member 520 by clamping the cross-shaped slot 310 with four clamps 522 at the top of the second connecting member 520; and realizes the assembly of the reflector 600 and the second connecting member 520 by clamping the clamping position 620 at the edge of the mounting hole 610 with the second clamping groove 521 at the bottom of the second connecting member 520. The vibrator 10 is detachably connected and locked to the reflector 600 by the second connecting member 520, which is simple to assemble and saves the material cost of screws and rivets.

[0048] In some embodiments, the second connecting member 520 is made of plastic.
