[0049] In base station antennas, the radome protects the antenna system from external environmental influences. Electrically, it provides excellent electromagnetic wave penetration and mechanically withstands harsh external environments (such as storms, snow, dust, and solar radiation). Base station antennas are typically equipped with additional radome supports to further stabilize the radome and prevent it from tipping over and damaging the antenna system.

[0050] Reference Figure 1, shows a schematic perspective view of a base station antenna according to an embodiment of the present disclosure. The base station antenna is generally indicated by reference numeral 100. As shown in the figure, base station antenna 100 includes a reflector 101, a radome support 102 mounted on reflector 101, a feed board (not shown), and a radiating element array 103 mounted on the feed board. The radome support 102 can support the radome (not shown) to maintain the stability of the radome and protect functional components mounted on reflector 101 within the radome, such as radiating element array 103.

[0051] Reference Figure 2a , showing Figure 1 Schematic top view of the base station antenna in FIG; Figure 2b , showing Figure 1 Schematic side view of the base station antenna in; Figure 2c , showing Figure 1 Schematic bottom view of the base station antenna in FIG; Figure 2d , showing the Figure 2b Schematic cross-sectional view taken along line AA in FIG.

[0052] In the present disclosure, the radiating element arrays 103 can be installed in rows and columns on or above the reflector 101 of the base station antenna 100. These radiating element arrays 103 can extend from the lower end to the upper end of the base station antenna 100 along the length direction V, and the length direction V can be in the direction of the longitudinal axis L of the base station antenna 100 or parallel to the longitudinal axis L. The length direction V is perpendicular to the width direction H and the front-to-back direction F. These radiating element arrays can extend forward from the feed plate along the front-to-back direction F. These radiating element arrays can be, for example, linear radiating element arrays of radiating elements or two-dimensional radiating element arrays of radiating elements. In the current embodiment, only two radiating element arrays are shown by way of example, namely a 4X2 low-frequency band radiating element array and an 8X2 high-frequency band radiating element array. In other embodiments, multiple radiating element arrays (for example, multiple high-frequency band radiating element arrays and / or multiple low-frequency band radiating element arrays) can be installed on the reflector 101.

[0053] In the present disclosure, the reflector 101 may include a main body 1011 and a bent portion 1012. The main body 1011 may be configured as a substantially flat surface, on or above which a series of functional components, such as a feed board and a radiation element array 103, may be mounted. The bent portion 1012 may be configured as a bent structure located laterally, such as on both sides, of the main body 1011.

[0054] Reference Figure 3a , which shows a schematic cross-sectional view of a first embodiment of a reflective plate 101 of the present disclosure. Figure 1The illustrated embodiment corresponds to the first embodiment of the reflective plate 101. Figure 3a As shown, the reflector 101 may include a main body 1011 in the middle and bent portions 1012 on both sides, that is, a bent portion 1012 may be provided on each side of the main body 1011. The main body 1011 may be configured as a main section with a substantially flat surface, on or above which the radiation element array 103 may be mounted for receiving and / or transmitting radio frequency signals. The bending portion 1012 can be configured as a multi-segment structure, such as a multi-segment hook-type structure, which may include a first segment 1012' connected to the main body 1011 and bent relative to the main body, a second segment 1012" connected to the first segment 1012' and bent relative to the first segment, and a third segment 1012'" connected to the second segment 1012" and bent relative to the second segment. In the first embodiment, the bending portions 1012 on both sides are bent toward each other. In other words, the distance between the third segments 1012'" on both sides is shorter than the distance between the first segments 1012' on both sides. The first segment 1012' is bent approximately 90° relative to the main body 1011 and extends substantially vertically downward from the main body 1011. The second segment 1012" is bent approximately 90° relative to the first segment 1012' and extends inward (i.e., the second segment on the left side extends to the right, and the second segment on the right side extends to the left). The third segment 1012'" is bent approximately 90° relative to the second segment 1012" and extends substantially vertically upward from the second segment 1012".

[0055] Reference Figure 3b , shows a schematic cross-sectional view of a second embodiment of the reflective plate 101 of the present disclosure. Figure 3bAs shown, the reflective plate 101 may include a central main portion 1011 and two bent portions 1012 on either side. The main portion 1011 may be configured as a main section with a substantially flat surface. The bent portion 1012 may be configured as a multi-segment structure, such as a multi-segment hook-shaped structure, including a first section 1012' connected to and bent relative to the main portion 1011, a second section 1012" connected to and bent relative to the first section 1012', and a third section 1012'" connected to and bent relative to the second section 1012". In the second embodiment, the bent portions 1012 on either side are bent away from each other. In other words, the distance between the third sections 1012' on either side is longer than the distance between the first sections 1012' on either side. The first section 1012' is bent approximately 90° relative to the main portion 1011 and extends substantially vertically downward from the main portion 1011. The second segment 1012" is bent approximately 90° relative to the first segment 1012' and extends outward (i.e., the second segment on the left side extends to the left, and the second segment on the right side extends to the right). The third segment 1012'" is bent approximately 90° relative to the second segment 1012" and extends essentially vertically upward from the second segment 1012".

[0056] Reference Figure 3c , shows a schematic cross-sectional view of a third embodiment of the reflective plate 101 of the present disclosure. Figure 3c As shown, the reflector 101 may include a central main portion 1011 and two bent portions 1012 on either side. The main portion 1011 and the bent portions 1012 may be integrally formed or joined via additional connecting devices. The main portion 1011 may be configured as a main section with a substantially flat surface. The bent portions 1012 may include a first section 1012' connected to the main portion 1011 and bent relative to the main portion. In a third embodiment, the first section 1012' is bent approximately 90° relative to the main portion 1011 and extends substantially vertically downward from the main portion 1011.

[0057] It should be understood that the various embodiments of the bending portion 1012 mentioned above in the present disclosure are merely exemplary, and the bending portion 1012 may also have other suitable variations.

[0058] In the present disclosure, the structural design of the bend portion 1012 can be advantageous: first, the bend portion 1012 of the present disclosure has a choke effect, which is beneficial to the RF performance of the antenna, such as the radiation pattern; second, the bend portion 1012 of the present disclosure can also play a bearing role (for example, a phase shift network and / or a feed network 104 can be installed on the bend portion 102). Figure 2c and Figure 2dA mounting bracket 105 may be fixed to the bend 1012, for example, the third section 1012'' of the bend 1012, and a phase shift network and / or feed network 104 for the radiating element array 103 may be mounted on the mounting bracket 105. This achieves a compact structure within a limited space. Advantageously, no electrical connection may exist between the bend 1012 and the phase shift network and / or feed network 104, which facilitates improving the passive intermodulation performance of the base station antenna 100.

[0059] In the present disclosure, the radome supports 102 may also be installed in rows and columns on the reflector 101 of the antenna to provide sufficient support for the radome. Figure 1 、 Figure 2a and 2c As can be seen in the figure, the radome support 102 can span from a first side of the reflector 101 (e.g., the main body 1011) to an opposite second side along the width direction H. The radome support 102 can be arranged at a certain distance from each other along the length direction V, and a plurality of radiating elements 103 can be arranged between two adjacent radome support members 102. The radome support 102 can extend forward from the reflector 101 along the front-to-back direction F and can be taller than the radiating elements 102, thereby effectively protecting the radiating elements 103 and preventing the radome from pressing on the radiating elements 103 and causing damage.

[0060] Next, with the help of Figure 4a 、 4b The radome support according to the present disclosure is described in detail. Figure 4a , showing a schematic perspective view of a radome support according to an embodiment of the present disclosure; referring to Figure 4b , showing a schematic front view of the radome support in 4a.

[0061] In the present disclosure, the radome support 102 can be configured as an arc-shaped injection molded part that can span from a first side of the reflector 101 (main body 1011) to an opposite second side along the width direction H. It should be noted that during performance testing of base station antennas, such as vibration testing, the stability of the radome support needs to be tested. The stability of the radome support in the width direction has a significant impact on both the mechanical and electrical performance of the base station antenna. The following will detail how the radome support according to the present disclosure is reliably and efficiently installed on the reflector, particularly ensuring the stability of the radome support in the width direction.

[0062] like Figure 1 、 Figure 4aAs shown, the radome support 102 may include a support portion 1021 for supporting the radome and a mating portion 1022 for mating with the reflector 101. A first support member limiting portion 1023 may be provided on the mating portion 1022 of the radome support 102. Correspondingly, a first reflector limiting portion 1013 is provided on the main body 1011 of the reflector 101 to mate with the first support member limiting portion 1023. The first support member limiting portion 1023 and the first reflector limiting portion 1013 cooperate to limit the position of the radome support 102 at least in the width direction H of the reflector 101.

[0063] In the present disclosure, the mating portion 1022 of the radome support 102 and the main portion 1011 of the reflector 101 can be advantageously mated: first, the radome support 102 can be installed through a "form fit" method, eliminating the need for a complex installation process; second, unlike the bent portion 1012 of the reflector 101, the main portion 1011 of the reflector 101 is configured as a substantially flat surface, thereby preventing additional errors in the manufacturing accuracy of the main portion 1011 of the reflector 101 from being introduced by the bending. In other words, the main portion 1011 of the reflector 101 can be manufactured with high precision. As a result, the first reflector stopper 1013 can be formed on the main portion 1011 of the reflector 101 with high precision, thereby preventing the radome support 102 from becoming difficult to install or causing poor stability due to manufacturing errors. According to the present disclosure, a tight fit can be achieved between the first reflector limit portion 1013 and the first support member limit portion 1023 , thereby at least improving the stability of the antenna cover support member 102 in the width direction H.

[0064] In some embodiments, the first support member limiting portion 1023 may be a component integrally formed on the mating portion 1022 of the radome support 102. In other embodiments, the first support member limiting portion 1023 may also be a component additionally mounted on the mating portion 1022 of the radome support 102.

[0065] In the current embodiment, the first support member limiting portion 1023 can be configured as a first protrusion 1023 provided on the matching portion 1022, and the first protrusion can extend from the matching portion 1022 body in the length direction V. Correspondingly, the first reflector plate limiting portion 1013 can be configured as a first groove provided on the main body 1011 of the reflector plate 101, and the first groove 1013 can also extend in the length direction V. The first protrusion 1023 can be configured to be snapped onto the first groove 1013, and the first groove 1013 can at least limit the position of the antenna cover support member in the width direction H. Figure 1The partial enlarged view clearly shows the engagement of the first protrusion 1023 with the first groove 1013. In the present disclosure, the first groove 1013 can be formed with high precision, achieving a tight fit between the first protrusion 1023 and the first groove 1013, advantageously preventing the groove from being too narrow or too wide, thereby avoiding difficult installation when the groove is too narrow or insufficient stability when the groove is too wide.

[0066] In other embodiments, the first support member limiting portion 1023 and the first reflector limiting portion 1013 can have any other suitable form. For example, the first support member limiting portion can also be configured as a snap portion provided on the mating portion, and the snap portion can extend from the mating portion toward the main body of the reflector. Accordingly, the first reflector limiting portion can be configured as a limiting hole on the main body of the reflector. Thus, when installing the radome support member to the reflector, the installation can be completed by simply snapping the snap portion on the radome support member into the corresponding limiting hole on the reflector. Here, the snap portion can limit the position of the radome support member in the width direction H, the length direction V, and the front-to-back direction F.

[0067] The matching of the mating portion of the radome support and the main body of the reflector is advantageous: unlike the bent portion of the reflector, the main body of the reflector is constructed as a substantially flat plane, so that the manufacturing accuracy of the main body of the reflector will not introduce additional errors due to the bending, that is, the main body of the reflector can have a higher manufacturing accuracy than the bent portion. As a result, the first reflector limiting portion can be formed on the main body of the reflector with higher accuracy, thereby preventing the installation of the radome support from becoming difficult or the stability from being deteriorated due to manufacturing errors. According to the present disclosure, a tight fit can be achieved between the first reflector limiting portion and the first support limiting portion, thereby at least improving the stability of the radome support in the width direction H.

[0068] In the present disclosure, a second support member limiting portion 1024 may also be provided on the matching portion 1022 of the antenna cover support 102, and a second reflector plate limiting portion 1014 may be provided on the bending portion 1012 of the reflector 101. The second reflector plate limiting portion matches the second support member limiting portion to limit the position of the antenna cover support 102 at least in the front-to-back direction F of the reflector 101.

[0069] In some embodiments, the second support member limiting portion 1024 can be configured as a second protrusion provided on the matching portion 1022, and the second protrusion 1024 can extend from the matching portion 1022 body in the width direction H. Correspondingly, the second reflector limiting portion 1014 can be configured as a second groove provided on the bent portion 1012 of the reflector 101, for example, the first section 1012'. The second protrusion 1024 can be configured to be snapped onto the second groove 1014. Figure 4a It can be clearly seen in the partial enlarged view that the second protrusion 1024 cooperates with the second groove 1014. In the present disclosure, by means of the tight fit between the second protrusion 1024 and the second groove 1014, the position of the antenna cover support can be limited at least in the front-to-back direction F.

[0070] In the present disclosure, an interference elastic portion 106 may be further provided on the mating portion 1022 of the radome support 102, and the interference elastic portion 106 may be integrally formed on the mating portion 1022 of the radome support 102. Figure 4a The interference spring portion 106 can be formed at the end of the mating portion 1022 and be configured as a hollow portion. The mating portion 1022 of the radome support 102 can at least partially extend through the through-slot in the reflector 101, allowing the interference spring portion 106 to rest against the inner surface of the bent portion 1012 of the reflector 101, such as the first section 1012'. According to the present disclosure, the interference fit between the interference spring portion and the bent portion of the reflector further improves the stability of the radome support, at least in the width direction H. Furthermore, the interference fit between the interference spring portion and the reflector advantageously prevents the radome support from tilting or deflecting on the reflector.

[0071] In the present disclosure, an opening 1025 may be provided on the radome support 102, for example, in the support portion 1021 thereof, and a parasitic element or a radio frequency debugging element may be installed through the opening. Figure 1 Parasitic elements (not shown for clarity) for corresponding radiating elements can be arranged around the radiating elements or between adjacent radiating elements through corresponding openings 1025. These parasitic elements are typically used to improve the beamforming of the radiating element array. For example, some parasitic elements can be configured to adjust the beamwidth of the radiating element array, while other parasitic elements can be configured to improve the isolation between adjacent radiating elements.

[0072] Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present disclosure without departing substantially from the spirit and scope of the present disclosure. Therefore, all such changes and modifications are intended to be within the scope of protection of the present disclosure as defined by the appended claims.
