[0022] Example 1

[0023] Regarding the aforementioned problem 1: Existing communication base station antennas on the market have the characteristic of narrow operating frequency bands. For example, outdoor directional single-polarized antennas operate in the 860-960MHz frequency band, while multi-band antennas suffer from high manufacturing costs.

[0024] The solution is as follows: A wideband high-gain directional antenna includes a device body 1, which comprises a reflective aluminum plate 2, a PCB substrate 3, and isolation pillars 4. The reflective aluminum plate 2 and the PCB substrate 3 are square-shaped, and the isolation pillars 4 are cylindrical. The PCB substrate 3 is located above the reflective aluminum plate 2. Several groups of isolation pillars 4 are installed on top of the reflective aluminum plate 2 in a horizontally equidistant manner. The PCB substrate 3 is installed on top of the several groups of isolation pillars 4. The top of the PCB substrate 3 is respectively provided with a first quadrant radiating element 5, a second quadrant radiating element 6, a third quadrant radiating element 7, and a fourth quadrant radiating element 8. The first quadrant radiating element 5, the second quadrant radiating element 6, the third quadrant radiating element 7, and the fourth quadrant radiating element 8 are distributed in a ring-shaped equidistant manner, and are perpendicular to each other. The first quadrant radiating element... Sub-5, second quadrant radiating array 6, third quadrant radiating array 7, and fourth quadrant radiating array 8 each include a radiating element feed array 9 and a ground feed array 10. The radiating element feed array 9 and ground feed array 10 are symmetrically distributed and have an elliptical structure. The surfaces of the radiating element feed array 9 and ground feed array 10 are provided with racetrack-shaped coupling slotted wiring 11, which has a capsule-shaped structure. The ground feed array 10... 0 is equipped with a coaxial cable 12, the other end of which is provided with an IPEX terminal 13. When in use, a common PCB substrate 3, a reflective aluminum plate 2, a riveted post-type isolation post 4 and screws are used to quickly connect the PCB substrate 3 and the reflective aluminum plate 2. The four coaxial cables 12 are welded to connect the first quadrant radiating array 5, the second quadrant radiating array 6, the third quadrant radiating array 7 and the fourth quadrant radiating array 8. The antenna MIMO form has higher gain, better isolation and wider frequency coverage.

[0025] Both the PCB substrate 3 and the reflective aluminum plate 2 have two sets of coaxial cable through holes 14. The two sets of coaxial cable through holes 14 are located on the bottom side of the first quadrant radiating array 5, the right side of the second quadrant radiating array 6, the top side of the third quadrant radiating array 7, and the right side of the fourth quadrant radiating array 8, respectively. The coaxial cable through holes 14 are for the purpose of facilitating the passage of the coaxial cable 12, thereby avoiding the radiating array.

[0026] Example 2

[0027] Regarding the second problem to be solved above: the existing directional antennas have relatively complex structures and high manufacturing costs.

[0028] The solution is as follows: Several sets of ring-shaped reflector screws 15 are provided on the outer surface of the PCB substrate 3. Several sets of ring-shaped equidistant positioning holes 16 are provided on the outer surface of the reflector aluminum plate 2. This solution mainly uses the reflector aluminum plate 2 and the PCB substrate 3, and the radiating unit on the PCB substrate 3 has four independent elements, thus achieving the purpose of simple structure and low manufacturing cost.

[0029] Working principle: During operation, this device uses a common PCB substrate 3, a reflective aluminum plate 2, a riveted column-type isolation column 4, and screws to quickly connect the PCB substrate 3 and the reflective aluminum plate 2. Four coaxial cables 12 are welded to connect the first quadrant radiating array 5, the second quadrant radiating array 6, the third quadrant radiating array 7, and the fourth quadrant radiating array 8. The antenna MIMO configuration has higher gain, better isolation, and a wider frequency coverage range.
