[0002] The continuous development of mobile communications and operators' increasing demands for network optimization have led to a continued increase in the use of antennas. However, network construction faces two major challenges. First, citizens are increasingly sensitive to antenna radiation and are resistant to antenna installation, making site selection for conventional base station antennas difficult and hindering site construction. Second, urban development has prompted many cities to implement their own planning and development needs, requiring operators to ensure that their antenna and feeder systems are consistent with the building's appearance to enhance the city's overall image. Therefore, antennas currently installed on buildings must not only meet various antenna specifications but also be compatible with the environment. Utility Model Content

[0020] Refer to Figure 1 and Figure 2 Specifically, the outer cover 6 includes a cover body 61, a top cover 62 and a lightning rod 63. One end of the cover body 61 is fixedly connected to the outer peripheral wall of the elevated frame 2 by a connector, and the other end of the cover body 61 is fixedly connected to the outer periphery of the fixing plate 5 by a connector, thereby wrapping the area between the elevated frame 2 and the fixing plate 5 to form a columnar body. The entire antenna is thus enclosed to form a miniaturized structure, thereby enhancing the concealment during installation, improving the overall aesthetics of the building and reducing visual interference to the public. The top cover 62 is coaxial with the cover body 61, and a cavity is provided in the top cover 62. One end of the cover body 61 is embedded in the cavity of the top cover 62, thereby sealing one side of the cover body 61. One end of the lightning rod 63 vertically penetrates the cavity of the top cover 62, the lightning rod 63 is coaxial with the cover body 61, and the other end of the lightning rod 63 extends out of the cavity of the top cover 62.

[0021] Furthermore, a wire hole 21 is provided on the side of the elevated frame 2 near the trough plates 1. The power cord passes through the wire hole 21 and into the space enclosed by each trough plate 1, where it connects to the power splitter board 4 fixed to each trough plate 1, thereby supplying power to the feed network on each trough plate 1. The trough plates 1 are arranged at an angle, with gaps between them, thereby forming a triangular prism-shaped area between the trough plates 1. The lightning rod 63 is coaxial with the wire hole 21, and there is a gap between the end of the lightning rod 63 and the fixed plate 5.

[0022] Furthermore, the two sides of the narrow surface of each slot plate 1 are inclined and extend outward, and the edges of each adjacent slot plate 1 are in a trumpet shape. A plurality of intermediate frequency radiation units 3 are arranged at intervals on the first wide surface of each slot plate 1, and the spacing between each intermediate frequency radiation unit 3 is equal. A plurality of power splitting boards 4 are fixed on the second wide surface of each slot plate 1, and a feeding network is provided on the surface of each power splitting board 4. A first isolation strip 7 is provided between each adjacent intermediate frequency radiation unit 3, and each first isolation strip 7 is parallel to each other. In addition, a second isolation strip 8 is provided on the outer periphery of the intermediate frequency radiation unit 3 located on the side close to the fixed plate 5, and the second isolation strip 8 is perpendicular to the first isolation strip 7. The first isolation strip 7 and the second isolation strip 8 are both fixed on the first wide surface of the slot plate 1, and the height of the first isolation strip 7 and the second isolation strip 8 are both lower than the height of each intermediate frequency radiation unit 3 on the same slot plate 1.

[0023] Preferably, in this embodiment, the operating frequency of each intermediate frequency radiation unit 3 is 1710MHz~2960MHz, and on the same slot plate 1, the spacing between each intermediate frequency radiation unit 3 is any value between 0.7 times and 0.9 times the wavelength corresponding to the center frequency point.

[0024] To sum up, the present invention uses a compact structural design to fix multiple slot plates for fixing intermediate frequency radiation units between the raising frame and the fixing plate, and encapsulates the raising frame and each slot plate together inside the outer cover through the outer cover, thereby improving the overall concealment of the antenna.
