[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] like Figures 1 to 5 As shown, the utility model is a dual-polarized 5G ultra-wideband directional vibrator antenna, including a reflective base plate 1, a 5G ultra-wideband directional vibrator 2, a BT steel sheet antenna 3, a vibrator radio frequency line 5, a BT radio frequency line 6, and an isolation column 4. The directional vibrator 2 is horizontally arranged above the reflective base plate 1, and the reflective base plate 1 and the directional vibrator 2 are connected by the isolation column 4. The directional vibrator 2 is provided with a vibrator welding point, and the vibrator radio frequency line 5 is connected to the vibrator welding point. The BT steel sheet antenna 3 is connected to the reflective base plate 1, the BT steel sheet antenna 3 is provided with a steel sheet welding point, and the BT radio frequency line 6 is connected to the steel sheet welding point.
[0021] Two directional vibrators 2 are connected to the reflective base plate 1, and each directional vibrator 2 is connected to two vibrator RF lines 5. The isolation column 4 is connected to the reflective base plate 1 and the directional vibrator 2 and is tightened and fixed by a nylon screw 8. The gain and angle of the antenna can be adjusted by adjusting the height of the isolation column 4. The directional vibrator 2 is designed as a short-circuit structure, and the frequency can be wider. The BT RF line 6 is used to connect to the motherboard of other devices. Using steel sheets as the high-frequency vibrator body can reduce losses.
[0022] The vibrator welding point includes a core wire welding point 21 and a braiding welding point 22. The core wire welding point 21 and the braiding welding point 22 are both arranged on the directional vibrator 2. The inner core wire of the vibrator RF line 5 is connected to the core wire welding point 21, and the outer part of the vibrator RF line 5 is connected to the braiding welding point 22. The core wire welding point 21 is used as the feeding point of the antenna to insert the core wire inside the vibrator RF line 5 for communication, while the braiding welding point 22 fixes the vibrator RF line 5, increases the fixing point of the vibrator RF line 5, and can avoid the problem of easy falling off due to only one welding point of the core wire.
[0023] The core wire welding point 21 and the braiding welding point 22 connected to the same vibrator RF line 5 are located diagonally to the center of the directional vibrator 2. Since the connection between the two vibrator RF lines 5 and the directional vibrator 2 is at a 45-degree angle, the core wire welding point 21 and the braiding welding point 22 are arranged diagonally to avoid bending of the core wire.
[0024] The surface of the directional oscillator 2 is provided with a slot 23. The slot 23 includes one or more of a horizontal slot, a vertical slot, and a 45-degree slot. In order to lengthen the current length, the antenna is adjusted through the slot 23 to reach the required frequency.
[0025] The dual-polarized 5G ultra-wideband directional vibrator 2 antenna also includes a heat sink 7, which is connected to the reflective bottom plate 1. The heat generated by the antenna can be dissipated in time through the heat sink 7 to ensure that the antenna is not damaged by high temperature.
[0026] The reflective bottom plate 1 is made of aluminum. The reflective bottom plate 1 is made of a full aluminum structure, and compared with conventional high-frequency boards, the cost of the antenna can be lower.
[0027] The material of the isolation column 4 is an insulating material, preferably nylon. The use of insulating material can ensure that the setting of the isolation column 4 does not affect the feeding efficiency of the antenna.
[0028] The directional oscillator 2 of this antenna product is dual-polarized with positive and negative 45 degrees, and the short-circuit structure is made by using the line layout of the directional oscillator 2. The frequency of the antenna is adjusted by calculating the antenna size and the slot 23 in the directional oscillator 2, and the gain and angle of the product are controlled by adjusting the height of the reflective bottom plate 1. This antenna achieves ultra-wideband, which can reach 3300-4200MHZ, while the frequency of conventional antennas is 3300-3800MHZ.
[0029] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
