[0002] An antenna oscillator is a component on an antenna, which has the functions of guiding and amplifying electromagnetic waves, so that the electromagnetic signals received by the antenna are stronger. The existing antenna oscillators for mobile communication base station antennas generally require high-performance ultra-wide-band antenna oscillators. For example, the "high-performance ultra-wide-band antenna oscillator" disclosed in the Chinese utility model patent with the authorization announcement number of CN108232401B.

[0003] However, in the above-mentioned prior art, in order to meet the wide-band requirements, the distance between two adjacent antenna oscillators in the array is often designed too narrow, which increases the influence between the antenna oscillators, resulting in the pattern distortion of a single oscillator in some frequency bands, and thus the sub-array pattern and the synthesized pattern in this frequency band are abnormal.

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Aiming at the technical problem that the pattern of a single oscillator in the existing broadband antenna oscillator is deformed in some frequency bands, which in turn leads to abnormalities in the sub-array pattern and the synthesized pattern in this frequency band, the present utility model proposes a narrow-spacing broadband antenna oscillator and an antenna. By improving the support structure, the influence between the oscillators can be effectively improved, and the problem of oscillator pattern deformation can be solved.

[0030] Combined with Figures 1-4 As shown, in a first aspect, the present utility model provides a narrow-spacing broadband antenna oscillator, including an oscillator 100. The oscillator 100 includes a main body 110 and a feeding sheet 120. The main body 110 includes four radiation sheets 111, four support columns 112 and a plurality of vertical arms 113. The four radiation sheets 111 are arranged at intervals in an array. Each radiation sheet 111 forms a notch at a corner of the inner circle. The two ends of the top of each of the four support columns 112 are respectively fixed to the bottom of two adjacent radiation sheets 111 and are located on one side of the notch. Every two adjacent support columns 112 are arranged at intervals to form a through groove 1123 corresponding to and communicating with the notch. The feeding sheet 120 is arranged in the through groove 1123. The vertical arms 113 are arranged at a corner of each radiation sheet 111 opposite to the corner with the notch and on two side edges adjacent to this corner.

[0031] In the present utility model, in order to solve the problem of abnormal pattern, the existing support balun is changed to the structural form of four support columns 112. Each support column 112 is composed of two columns arranged at intervals. The bottoms of the two columns are connected together, and the interval between the upper parts is equal to the interval between two adjacent radiation sheets 111, and is used to support the adjacent ends of the two adjacent radiation sheets 111 close to each other. The intervals between two adjacent support columns 112 are also arranged at intervals, and this interval is equal to the width of the notch formed at a corner of the radiation sheet 111. In this way, the feeding sheet 120 is arranged in the through groove 1123, and the side of the feeding sheet 120 is not completely closed, effectively improving the influence between the radiation sheets 111 in the array, solving the problem of the pattern deformation of the radiation sheet 111 of a single oscillator in some frequency bands, and thus solving the technical problem of abnormalities in the sub-array pattern and the synthesized pattern in this frequency band.

[0032] At the same time, in order to meet the broadband requirements, in addition to arranging a vertical arm 113 at each corner of the inner circle of the four radiation sheets 111, vertical arms 113 are also respectively arranged on two side edges adjacent to this corner, broadening the frequency band of the oscillator 100.

[0033] In one embodiment, as Figure 5 shown, the oscillator 100 further includes a fixing member 130. The fixing member 130 is disposed in the middle gap surrounded by the four radiating sheets 111 and is used to fix the feeding sheet 120 in the through slot 1123.

[0034] In one embodiment, the fixing member 130 includes a fixing base 131 and feeding legs 132. The bottom of the fixing base 131 is disposed on the tops of the four feeding legs 132. The four feeding sheets 120 are mounted on the top of the fixing base 131. The four feeding legs 132 are respectively located in the corresponding through slots 1123. And two of the feeding legs 132 on one side are disposed in a suspended manner, while two of the feeding legs 132 on the other side pass through the through slots 1123.

[0035] In one embodiment, in order to install the fixing member 130, on one end face of each support post 112 facing the center of the main body 110, a protrusion 1121 extending towards the center of the main body 110 is formed along the height direction of the support post 112. The tops of the four protrusions 1121 are connected to the bottom of the fixing base 131 to fix the fixing base 131.

[0036] In one embodiment, the heights of the four protrusions 1121 are equal and less than the height of the support post 112, so as to install the four feeding sheets 120 in the through slots 1123 and the sides are not closed.

[0037] In one embodiment, an avoidance portion 1122 is formed at the bottom of the through slot 1123 where the feeding leg 132 passes through the through slot 1123 and is used to avoid the feeding leg 132 when the feeding leg 132 is connected to the PCB board 200.

[0038] In one embodiment, the main body 110 further includes a connecting plate 114. The four sides of the connecting plate 114 are respectively connected to the bottoms of the four support posts 112 to make the four support posts 112 an integral body. A pin post 1141 is disposed at the center of the bottom of the connecting plate 114. That is to say, the four support posts 112 and the connecting plate 114 are of an integrally formed structure.

[0039] In one embodiment, the antenna oscillator further includes a PCB board 200 disposed at the bottom of the oscillator 100. A first mounting hole 210 for mating connection with the pin post 1141 and a second mounting hole 220 for mating connection with the feeding leg 132 are formed on the PCB board 200.

[0040] In one of the embodiments, the antenna element further includes a base 300 disposed at the bottom of the PCB board 200. The base 300 is composed of a bottom plate 310 and two side plates 320. The two side plates 320 are respectively disposed on both sides of the bottom plate 310. A window 330 is formed on the bottom plate 310 for exposing the feed leg 132 to connect to other external components.

[0041] In a second aspect, the present invention further provides an antenna, which includes the antenna element described in the first aspect of the present invention.

[0042] In summary, the narrow-spacing broadband antenna element and antenna provided by the present invention can effectively improve the influence between the elements on the premise of meeting the broadband requirements, thereby avoiding the occurrence of abnormal radiation patterns of the elements in the array.
