Technical Field

[0001] The utility model relates to the technical field of antennas, and in particular to a multi-port high-gain directional CPE flat antenna. Background Art

In addition, conventional CPE flat antennas will place the antenna feed lines on both sides of the oscillator. Such a structure not only affects the isolation of the antenna, but also increases the size of the antenna, resulting in a problem of fewer ports that can be set. Utility Model Content

[0017] 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.

[0018] like Figures 1 to 3 As shown, a multi-port high-gain directional CPE flat-panel antenna of the utility model comprises a reflective base plate 1, an antenna vibrator 2, a guiding vibrator 3, a radio frequency line 5, and an isolation column 4. The guiding vibrator 3, the antenna vibrator 2, and the reflective base plate 1 are arranged in parallel from top to bottom, and the guiding vibrator 3 and the antenna vibrator 2, and the antenna vibrator 2 and the reflective base plate 1 are supported and connected by the isolation column 4. A feeding port 6 is provided in the middle of the reflective base plate 1 and the antenna vibrator 2, and the radio frequency line 5 is connected to the feeding port 6.

[0019] The gain and impedance of the antenna are adjusted by adjusting the height of the isolation column 4 between the antenna vibrator 2 and the reflective bottom plate 1. The antenna vibrator 2 is placed flat on the reflective bottom plate 1, and the height of the reflective bottom plate 1 is controlled to adjust the gain of the entire antenna. The guide vibrator 3 is at the top of the entire product to increase the gain of the antenna. The height between the guide vibrator 3 and the antenna vibrator 2, and between the antenna vibrator 2 and the reflective bottom plate 1 is adjusted by isolation columns 4 of different thicknesses. At the same time, the isolation columns 4 can also play a supporting and connecting role for the reflective bottom plate 1, the antenna vibrator 2, and the guide vibrator 3.

[0020] A guiding region is provided at each end of the antenna element 2, each guiding region is connected to a guiding element 3 through an isolation column 4, and the two guiding regions are connected through an impedance line 9 of the antenna element 2, and the impedance line 9 extends to the feeding port 6. A guiding element 3 is connected to the top of each end of the antenna element 2, and a guiding region matching the shape of the guiding element 3 is provided in the corresponding area to achieve the effect of antenna gain.

[0021] The feed port 6 is located in the middle of the two guiding areas. When the size is not wide enough, the feed line of the antenna is made to come out from the middle of the two guiding oscillators 3. Since the size of the entire antenna is relatively small, there is no position for the line to come out on both sides of the antenna oscillator 2. In this fixed size, the two feed ports 6 can only come out from the middle of the guiding area.

[0022] The director vibrator 3 is a circular structure. The director vibrator 3 adopts a circular design, which makes the director vibrator 3 easier to assemble, and does not need to be divided into directions, and can be directly assembled.

[0023] The multi-port high-gain directional CPE flat antenna also includes a stud 7 and a nut 8. The stud 7 passes through the isolation column 4 and is fastened by the nut 8. The stud 7 passes through two isolation columns 4, thereby limiting the positional relationship between the reflective bottom plate 1, the antenna vibrator 2, the guide vibrator 3 and the isolation column 4. The nut 8 is tightened on the stud 7 and fixes the various structural components of the antenna.

[0024] The material of the isolation column 4 is an insulating material, preferably nylon. The use of the insulating material can ensure that the setting of the isolation column 4 does not affect the feeding efficiency of the antenna.

[0025] The reflective bottom plate 1, the antenna vibrator 2, and the guide vibrator 3 are made of aluminum. The radiator adopts a full aluminum structure, and compared with the conventional PCB board structure, the cost of the antenna can be made lower.

[0026] The material of the radio frequency line 5 is tin wire, which can meet the wireless signal transmission requirements of the antenna.

[0027] 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.
