Description

TECHNICAL FIELD

[0001] The utility model relates to antenna technical field especially relates to a low profile coupling broadband antenna. BACKGROUND

[0002] Common low profile antenna includes microstrip antenna, and the microstrip antenna is a typical low profile antenna, which is usually made on a printed circuit board and is composed of a radiation patch, a ground plate and a dielectric substrate. The thickness of the microstrip antenna is usually much smaller than its working wavelength, so it has a low profile height. In an outdoor scene, the printed circuit board has a short service life, weak wind resistance, cannot withstand high power continuous waves, the beam width cannot be less than 45 degrees, and the gain is greater than or equal to 6dBi. Therefore, the overall structure is poor in stability and mechanical properties, and is prone to damage in an outdoor scene. SUMMARY

[0013] Preferably, the tuning oscillator includes a metal plate and a copper square patch fixed on the metal plate.

[0014] (III) Beneficial Effects

[0015] The oscillator, reflector, and stepped folded power supply network form a stable mechanical structure with good wind resistance and stable and reliable electrical performance. It can carry 400W of high power and is suitable for outdoor applications.

[0016] Meanwhile, the first support column ensures effective impedance matching between the tuning vibrator and the reflector by maintaining a sufficient distance between them. Furthermore, the reflection from the reflector weakens the backward radiation energy of the tuning vibrator, giving the entire antenna directional radiation characteristics.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] See Figures 1-3 As shown in the figure, an embodiment of this utility model proposes a low-profile coupled broadband antenna, including a tuning element 1 and multiple first support columns 2 mounted on the tuning element 1. A reflector 3 located below the tuning element 1 is mounted on the first support columns 2. The tuning element 1 and the reflector 3 are relatively fixed by the first support columns 2, and the spacing is satisfied to ensure effective impedance matching. The reflector 3 is located below the tuning element 1, which can reduce the back-radiated energy of the tuning element 1, so that the entire antenna has directional radiation characteristics. The frame structure formed by the tuning element 1, the first support columns 2 and the reflector 3 is stable and has good wind resistance.

[0025] Meanwhile, a positioning and fixing block 4 is installed between the adjusting vibrator 1 and the reflector 3. A stepped folded feed network vibrator 5 is installed on the positioning and fixing block 4. The stepped folded feed network vibrator 5 includes a first bent portion 6 and a second bent portion 7. The adjusting vibrator 1 is also provided with an insulated second support column 8, which is installed on the reflector 3. The first bent portion 6 is sleeved on the second support column 8, and the first bent portion 6 is spaced apart from the adjusting vibrator 1, with air as the medium in between. A connector socket 9 is installed on the reflector 3, and the second bent portion 7 is connected to the connector socket 9. The connector socket 9 is used to insert external wires. After the current passes through the stepped folded feed network vibrator 5 and the air medium, it is coupled to the adjusting vibrator 1 and then radiated outward, increasing the radiation efficiency, improving the gain, and reducing the voltage standing wave ratio.

[0026] The improved mechanical properties of the entire antenna structure make it suitable for outdoor applications, and its strong structural strength allows it to withstand 400W of high power.

[0027] The second bend 7 and the connector socket 9 need to have good conductivity and be insulated from the reflector 3. A connecting pin 10 is fixed to the second bend 7. The connecting pin 10 is threadedly connected to the inner conductor of the connector socket 9. A first insulating sleeve 11 is fitted on the connecting pin 10. The first insulating sleeve 11 realizes the insulating connection between the connecting pin 10 and the reflector 3 and ensures a stable connection with the inner conductor of the connector socket 9, thereby having good conductivity.

[0028] To further enhance the wind resistance of the entire antenna structure and reduce wind interference, several air guide holes 12 are arranged in an array on the tuning element 1, avoiding the stepped folded feed network element 5. These air guide holes 12 allow for airflow, reducing the wind force on the tuning element 1 and maintaining stability even in windy conditions. Furthermore, avoiding direct wind blowing towards the stepped folded feed network element 5 ensures signal stability.

[0029] To ensure the structural stability of the tuning oscillator 1, the long edge of the tuning oscillator 1 is bent downward to form a side plate 13. The bent side plate 13 structure avoids deformation.

[0030] Specifically, the tuning oscillator 1 includes a metal plate and a copper square patch fixed on the metal plate to ensure structural stability and signal stability.

[0031] When installing the first support column 2, deformation of the adjusting vibrator 1 and the reflector 3 should be avoided. Therefore, a first flange 14 is provided at one end of the first support column 2 and a second flange 15 is provided at the other end. The first flange 14 is installed on the adjusting vibrator 1 and the second flange 15 is installed on the reflector 3.

[0032] Meanwhile, to prevent deformation of the adjusting vibrator 1 and the reflector 3 during the installation of the second support column 8, a second insulating sleeve 16 is fitted on one end of the second support column 8, and a second flange 15 is provided on the other end. The second insulating sleeve 16 is installed on the adjusting vibrator 1, and the second flange 15 is installed on the reflector 3.
