In a base station antenna, a radome is a structure that protects an antenna system from an external environment. The antenna cover has good electromagnetic wave penetration characteristics in electrical performance, and can withstand the action of external severe environments (such as storm, ice and snow, sand and dust, solar radiation and the like) in mechanical performance. A radome support member is also typically additionally installed in the base station antenna for supporting the radome to further stabilize the radome against toppling over of the radome and damaging the antenna system.

Referring to fig. 1, a schematic perspective view of a base station antenna according to one embodiment of the present disclosure is shown. A base station antenna is generally indicated by reference numeral 100. As shown, the base station antenna 100 includes a reflector plate 101, a radome support 102 mounted on the reflector plate 101, a feed plate (not shown), and an array of radiating elements 103 mounted on the feed plate. The radome carrier 102 may support a radome, not shown, to maintain stability of the radome and protect functional components, such as the array of radiating elements 103, etc., mounted on the reflector plate 101, inside the radome.

Referring to fig. 2a, there is shown a schematic top view of the base station antenna of fig. 1; referring to fig. 2b, there is shown a schematic side view of the base station antenna of fig. 1; referring to fig. 2c, a schematic bottom view of the base station antenna of fig. 1 is shown; referring to fig. 2d, a schematic cross-sectional view is shown, taken along the sectional line a-a in fig. 2 b.

In the present disclosure, the array of radiating elements 103 may be mounted on or above the reflective plate 101 of the base station antenna 100 in rows and columns. These arrays of radiating elements 103 may extend from the lower end to the upper end of the base station antenna 100 along a length direction V, which may be in the direction of the longitudinal axis L of the base station antenna 100 or parallel to the longitudinal axis L. The longitudinal direction V is perpendicular to the width direction H and the front-rear direction F. The arrays of radiating elements may extend forward from the feed panel in a forward-to-backward direction F. These arrays of radiating elements may be, for example, linear arrays of radiating elements or two-dimensional arrays of radiating elements. In the present embodiment, only two arrays of radiating elements are shown by way of example, one 4X2 array of low band radiating elements and one 8X2 array of high band radiating elements. In other embodiments, multiple arrays of radiating elements (e.g., multiple arrays of high-band radiating elements and/or multiple arrays of low-band radiating elements) may be mounted on the reflector plate 101.

In the present disclosure, the reflection plate 101 may include a main body portion 1011 and a bent portion 1012. The main body 1011 may be configured as a substantially flat plane, and a series of functional components, such as a feed board and the radiating element array 103, may be mounted on or above the main body 1011. The bent portion 1012 may be configured as a bent structure located laterally to the main body portion 1011, for example, on both sides.

Referring to fig. 3a, a schematic cross-sectional view of a first embodiment of a reflective plate 101 of the present disclosure is shown. The example shown in fig. 1 corresponds to the first embodiment of the reflection plate 101. As shown in fig. 3a, the reflective plate 101 may include a main body 1011 at the middle and two bending portions 1012 at both sides, that is, one bending portion 1012 may be provided at both sides of the main body 1011. The body portion 1011 may be configured as a main section with a substantially planar surface upon or over which the array of radiating elements 103 may be mounted for receiving and/or transmitting radio frequency signals. The bent portion 1012 may be configured as a multi-segmented structure, for example, a multi-segmented hook-type structure, which may include a first segment 1012' connected to the main body 1011 and bent with respect to the main body, a second segment 1012' connected to the first segment 1012' and bent with respect to the first segment, and a third segment 1012' ″ connected to the second segment 1012' and bent with respect to the second segment. In the first exemplary embodiment, the two side folds 1012 are bent toward one another, in other words, the distance between the two side third sections 1012'″ is shorter than the distance between the two side first sections 1012'. The first section 1012' is bent approximately 90 ° relative to the main body 1011 and extends substantially perpendicularly downward from the main body 1011. The second section 1012 "is bent approximately 90 ° relative to the first section 1012' and extends inward (i.e., the left second section is to the right and the right second section is to the left). The third section 1012' "is bent approximately 90 ° relative to the second section 1012" and extends substantially perpendicularly upward from the second section 1012 ".

Referring to fig. 3b, a schematic cross-sectional view of a second embodiment of the reflective plate 101 of the present disclosure is shown. As shown in fig. 3b, the reflective plate 101 may include a main body portion 1011 at the middle and bent portions 1012 at both sides. The body portion 1011 may be configured as a main section with a substantially flat surface. The bent portion 1012 may be configured as a multi-segmented structure, for example, a multi-segmented hook-type structure, which may include a first segment 1012' connected to the main body 1011 and bent with respect to the main body, a second segment 1012' connected to the first segment 1012' and bent with respect to the first segment, and a third segment 1012' ″ connected to the second segment 1012' and bent with respect to the second segment. In the second exemplary embodiment, the two side folds 1012 are bent away from one another, in other words the distance between the two side third portions 1012'″ is longer than the distance between the two side first portions 1012'. The first section 1012' is bent approximately 90 ° relative to the main body 1011 and extends substantially perpendicularly downward from the main body 1011. The second section 1012 "is bent approximately 90 ° relative to the first section 1012' and extends outward (i.e., the left-hand second section is to the left, and the right-hand second section is to the right). The third section 1012' "is bent approximately 90 ° relative to the second section 1012" and extends substantially perpendicularly upward from the second section 1012 ".

Referring to fig. 3c, a schematic cross-sectional view of a third embodiment of the reflective plate 101 of the present disclosure is shown. As shown in fig. 3c, the reflective plate 101 may include a main body portion 1011 at the middle and bent portions 1012 at both sides. The main body 1011 may be integrally formed with the bent portion 1012 or may be joined by an additional connecting means. The body portion 1011 may be configured as a main section with a substantially flat surface. The bend 1012 may include a first section 1012' connected to and bent relative to the main body 1011. In the third embodiment, the first section 1012' is bent approximately 90 ° relative to the main body 1011 and extends substantially perpendicularly downward from the main body 1011.

It should be understood that the above-mentioned embodiments of the bending portion 1012 in the present disclosure are only exemplary, and the bending portion 1012 may have other suitable modifications.

In the present disclosure, the structural design of the bend 1012 may be advantageous: first, the bending part 102 of the present disclosure has a choke effect, which is advantageous to the radio frequency performance of the antenna, such as a radiation pattern; second, the bend 1012 of the present disclosure may also be load-bearing (e.g., the phase shifting network and/or the feed network 104 may be mounted on the bend 102). Referring to fig. 2c and 2d, a mounting bracket 105 may be fixed to the bend 1012, for example, to the third section 1012' ″ of the bend 1012, and a phase shifting network and/or a feeding network 104 for the array of radiating elements 103 may be mounted on the mounting bracket 105. Thereby achieving a compact structure in a limited space. Advantageously, there may be no electrical connection between the bend 1012 and the phase shifting network and/or the feed network 104, which is beneficial for improving the passive intermodulation performance of the base station antenna 100.

In the present disclosure, the radome mounts 102 may also be mounted on the reflector plate 101 of the antenna in rows and columns for providing adequate support for the radome. As can be seen in fig. 1, 2a and 2c, the radome support 102 may span in the width direction H from a first side to an opposite second side of the reflector plate 101 (e.g., the body portion 1011). The radome supports 102 may be arranged at a distance from each other along the length direction V, and several radiation elements 103 may be arranged between two adjacent radome supports 102. The radome carrier 102 may extend forward from the reflection plate 101 in the front-rear direction F and the height of the radome carrier 102 may be higher than that of the radiation element 102, so that the radiation element 103 can be effectively protected from damage caused by the radome pressing against the radiation element 103.

Next, a radome support according to the present disclosure is explained in detail with the aid of fig. 4a, 4 b. Referring to fig. 4a, a schematic perspective view of a radome carrier is shown according to one embodiment of the present disclosure; referring to fig. 4b, a schematic front view of the radome carrier in fig. 4a is shown.

In the present disclosure, the radome support member 102 may be configured as an arc-shaped injection-molded member that may span from a first side to an opposite second side of the reflection plate 101 (body portion 1011) in the width direction H. It should be noted that in performance tests of the base station antenna, such as vibration tests, the stability of the radome support member needs to be tested, wherein the stability of the radome support member in the width direction has an important influence on both the mechanical and electrical properties of the base station antenna. It will be explained in detail below how a radome carrier according to the present disclosure can be mounted on a reflector plate in a reliable and efficient manner, in particular ensuring stability of the radome carrier in the width direction.

As shown in fig. 1 and 4a, the radome holder 102 may include a support portion 1021 for supporting the radome and a mating portion 1022 for mating with the reflection plate 101. The mating portion 1022 of the radome support member 102 may have a first support member stopper 1023 disposed thereon. Accordingly, the main body 1011 of the reflection plate 101 is provided with a first reflection plate stopper 1013 that fits the first support stopper 1023. The first support stopper 1023 and the first reflector stopper 1013 cooperate to restrict the position of the radome support 102 at least in the width direction H of the reflector 101.

In the present disclosure, the mating of the mating portion 1022 of the radome carrier 102 with the body portion 1011 of the reflector plate 101 may be advantageous: first, the mounting of the radome carrier 102 can be achieved in a "form-fit" manner, without costly mounting procedures; second, unlike the bent portion 1012 of the reflection plate 101, the main body portion 1011 of the reflection plate 101 is configured as a substantially flat plane, so that the manufacturing accuracy of the main body portion 1011 of the reflection plate 101 does not cause an additional error due to the bending, that is, the main body portion 1011 of the reflection plate 101 can have a high manufacturing accuracy. Thereby, the first reflection plate stopper 1013 can be formed on the main body portion 1011 of the reflection plate 101 with high accuracy, thereby preventing the radome 102 from being difficult to mount or deteriorated in stability due to a manufacturing error. According to the present disclosure, a close fit between the first reflector plate stopper part 1013 and the first support stopper part 1023 can be achieved, thereby improving at least the stability of the radome support 102 in the width direction H.

In some embodiments, the first support limiting portion 1023 may be a component integrally molded on the mating portion 1022 of the radome support 102. In other embodiments, the first support limiting portion 1023 may be a component attached to the mating portion 1022 of the radome support member 102.

In the current embodiment, the first support limiting portion 1023 may be configured as a first protruding portion 1023 provided on the mating portion 1022, and the first protruding portion may protrude from the body of the mating portion 1022 in the length direction V. Accordingly, the first reflection plate stopper 1013 may be configured as a first recess provided in the main body 1011 of the reflection plate 101, and the first recess 1013 may extend in the longitudinal direction V. The first protrusion 1023 can be configured to snap into the first recess 1013, the first recess 1013 restricting the position of the radome support member at least in the width direction H. The engagement of the first protrusion 1023 with the first recess 1013 is clearly seen in the enlarged partial view of fig. 1. In the present disclosure, the first recess 1013 can be constituted with high precision, the close fitting of the first protrusion 1023 with the first recess 1013 is achieved, and the dimension of the recess being too narrow or too wide is advantageously prevented, thereby avoiding difficult mounting in case of too narrow recess or insufficient stability of fitting in case of too wide recess.

In other embodiments, the first support limiting part 1023 and the first reflection plate limiting part 1013 may have any other suitable form. For example, the first support stopper portion may be formed as a locking portion provided on the engagement portion, and the locking portion may extend from the engagement portion toward the main body portion of the reflection plate. Accordingly, the first reflection plate stopper portion may be configured as a stopper hole in the main body portion of the reflection plate. From this, at the in-process of installing the radome member to the reflecting plate, only need directly buckle the buckle portion on the radome member in the corresponding spacing hole on the reflecting plate and can accomplish the installation. Here, the locking portion may limit the position of the radome receiver in the width direction H, the length direction V, and the front-rear direction F.

The mating of the mating portion of the radome carrier with the body portion of the reflector plate is advantageous: unlike the bent portion of the reflection plate, the main body portion of the reflection plate is configured as a substantially flat plane, so that the manufacturing accuracy of the main body portion of the reflection plate does not introduce an additional error due to the bending, that is, the main body portion of the reflection plate can have a higher manufacturing accuracy than the bent portion. Thereby, the first reflector plate stopper portion can be formed on the main body portion of the reflector plate with high accuracy, thereby preventing the mounting of the radome carrier from becoming difficult or the stability from deteriorating due to the manufacturing error. According to the present disclosure, a close fit of the first reflector plate stopper portion and the first support stopper portion can be achieved therebetween, thereby improving at least the stability of the radome support in the width direction H.

In the present disclosure, a second support member stopper 1024 may be further provided on the fitting portion 1022 of the radome support member 102, and a second reflector plate stopper 1014, which is fitted with the second support member stopper, is provided on the bent portion 1012 of the reflector plate 101 for restricting the position of the radome support member 102 at least in the front-rear direction F of the reflector plate 101.

In some embodiments, the second support-limiting part 1024 may be configured as a second protrusion provided on the mating part 1022, and the second protrusion 1024 may protrude from the body of the mating part 1022 in the width direction H. Accordingly, the second reflection plate stopper 1014 may be configured as a second groove provided on the bent portion 1012, for example, the first section 1012' of the reflection plate 101. Second projection 1024 may be configured to snap onto second recess 1014. The mating of the second projection 1024 with the second recess 1014 is best seen in the enlarged partial view of fig. 4 a. In the present disclosure, the position of the radome support member can be restricted in at least the front-rear direction F by means of the close fit between the second protrusion 1024 and the second recess 1014.

In the present disclosure, an interference elastic portion 106 may also be provided on the mating portion 1022 of the radome carrier 102, and the interference elastic portion 106 may be integrally molded on the mating portion 1022 of the radome carrier 102. Referring to fig. 4a, the interference elastic part 106 may be formed on an end of the fitting part 1022 and be formed as a hollow part. The mating portion 1022 of the radome support 102 can be at least partially passed through the through slot in the reflector plate 101, and the interference elastic portion 106 can thereby be interference-abutted against the inner surface of the bend 1012, e.g., the first section 1012', of the reflector plate 101. According to the present disclosure, the interference fit between the interference elastic portion and the bent portion of the reflector plate, thereby further improving at least the stability of the radome support member in the width direction H. Furthermore, by means of the interference fit of the interference elastic portion with the reflector plate, tilting or deflection of the radome support member on the reflector plate is advantageously prevented.

In the present disclosure, an opening 1025 may be provided on the radome support 102, for example, within the support 1021 thereof, by means of which a parasitic element or a radio frequency commissioning element can be mounted. Referring to fig. 1, parasitic elements (not shown for clarity) for respective radiating elements may be disposed around the radiating elements or between adjacent radiating elements through respective openings 1025. These parasitic elements are typically used to improve the beamforming of the array of radiating elements. For example, a portion of the parasitic elements may be configured to adjust a beam width of the array of radiating elements, for example, while another portion of the parasitic elements may be configured to improve isolation between adjacent radiating elements.

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 can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure.
