Description

Technical Field

[0001] This invention belongs to the field of mobile communication technology, and specifically relates to an antenna assembly and an antenna configured with the antenna assembly. Background Technology

[0002] With the rapid development of modern mobile communication technology, users' demand for high-capacity, low-latency communication is increasing daily, leading to the emergence of fifth-generation mobile communication networks. In the construction of 5G mobile communication networks in China, multiple network standards need to be developed in tandem, such as 5G and 4G networks operating simultaneously. However, different network standards require antennas in different frequency bands, resulting in a dramatic increase in the number of antennas at each base station site. This significantly increases the construction and maintenance costs of antenna base station sites, leading to a waste of antenna environmental resources, and excessive antennas also negatively impact the urban landscape.

[0003] To address these issues, the industry has proposed a solution involving nesting high-frequency and low-frequency antenna elements. This embeds the high-frequency element within the low-frequency element to improve antenna space utilization and save rooftop resources. However, when the high-frequency element is embedded within the low-frequency element, electrical insulation between them is not achieved. Furthermore, because they are mounted on the same reflector, strong coupling exists between them, significantly impacting their radiation performance. This leads to deteriorated port isolation and pattern distortion between antennas of different frequency bands, ultimately affecting the performance of the synthesized beam of the multi-frequency antenna. Summary of the Invention

[0004] The purpose of this invention is to solve at least one of the above-mentioned problems by providing an antenna assembly and an antenna.

[0005] To meet the various objectives of this invention, the following technical solutions are adopted:

[0006] An antenna assembly is provided to suit one of the purposes of this invention, comprising:

[0007] The oscillator mounting base includes a base and a mounting post fixed on the base. The free end of the mounting post forms a mounting platform, and the mounting platform forms a power supply plug slot. The power supply plug slot is connected to the outside of the base through a wiring channel.

[0008] A first oscillator having a first radiating aperture includes a base and a radiating arm supported on the base, the base having a plug pin electrically connected to the radiating arm, the plug pin being inserted into the feed plug slot;

[0009] A second oscillator with a second radiating aperture includes a base and a radiating arm supported on the base. The base is fitted into the mounting post and fixed to the base. The second radiating aperture is larger than the first radiating aperture.

[0010] Furthermore, the first oscillator is a high-frequency oscillator, and the second oscillator is a low-frequency oscillator.

[0011] Furthermore, the radiating arm of the second oscillator surrounds the polarization center of the second oscillator to form a receiving groove, and the mounting platform is disposed in the receiving groove.

[0012] Furthermore, the first oscillator is disposed within the receiving groove.

[0013] Furthermore, the base forms a first periphery on the outside of the mounting column, and the base of the second oscillator is supported on the first periphery.

[0014] Furthermore, the antenna assembly also has a reflector corresponding to the first vibrator, and the free end forms a second periphery on the outside of the mounting platform, the second periphery being used to mount and support the reflector.

[0015] Specifically, the power supply plug slot is provided with multiple limiting clips, which are engaged with the plug pins of the first oscillator.

[0016] Specifically, the base is provided with an assembly structure for assembly with an external base plate. The assembly structure includes multiple elastic clips, which are used to be installed in mounting holes on the base plate.

[0017] Furthermore, the second oscillator has a mounting hole formed on its base, and the mounting post fits into the mounting hole to place the base of the second oscillator on the base.

[0018] In one embodiment, the second oscillator has two dipoles belonging to the same polarization and two feeding components that feed the two dipoles respectively. One end of each of the two feeding components is electrically connected to its corresponding dipole, and the other end of each component is combined through the same physical combining port inherent to the second oscillator. Each dipole is composed of a pair of adjacent radiating arms.

[0019] An antenna is provided to suit one of the purposes of the present invention, comprising an antenna assembly as described in any one of the preceding purposes.

[0020] Compared with existing technologies, the present invention has many advantages, including but not limited to:

[0021] On the one hand, the vibrator mounting base of the antenna assembly of the present invention is used to support the second vibrator, and the mounting post of the vibrator mounting base extends into the second vibrator to fix the first vibrator through the mounting post, so that the first vibrator is installed inside the second vibrator, saving antenna installation space, making the antenna miniaturized and easy to manufacture and install.

[0022] On the other hand, the antenna assembly of the present invention can separate the first oscillator and the second oscillator, reduce the mutual coupling between the first oscillator and the second oscillator, achieve electrical isolation, and improve the radiation performance of the first oscillator and the second oscillator, so that the first oscillator can be embedded in the second oscillator, and the two oscillators do not affect the radiation performance of each other.

[0044] The present invention provides an antenna assembly, the antenna assembly including a first element embedded in a second element, the first element being mounted in the second element via an element mounting base, the element mounting base separating the first element and the second element, reducing mutual coupling between the first element and the second element, achieving electrical isolation, and improving the radiation performance of the first element and the second element.

[0045] In a typical embodiment of the present invention, combined with Figure 1 The antenna assembly 100 includes a first vibrator 110, a second vibrator 120, and a vibrator mounting base 130. The first vibrator 110 has a first radiation aperture, and the second vibrator 120 has a second radiation aperture, which is larger than the first radiation aperture, so that the first vibrator 110 can be embedded in the second vibrator 120 through the vibrator mounting base 130. In one embodiment, the first vibrator 110 is a high-frequency vibrator, and the second vibrator 120 is a low-frequency vibrator.

[0046] Specifically, in combination Figure 2 The first oscillator 110 includes a first base 111 and a plurality of first radiating arms 112 supported on the first base 111. The first base 111 includes a plurality of first plug pins 1111, and the first plug pins 1111 are electrically connected to the corresponding first radiating arms 112. In one embodiment, the first plug pins 1111 are balun arms.

[0047] Combination Figure 3 The second oscillator 120 includes a second base 121 and a plurality of second radiating arms 122 supported on the second base 121. The plurality of second radiating arms 122 are arranged around a common center, which is the polarization center of the second oscillator 120. The second base 121 includes a plurality of second plug pins 1211, which are electrically connected to the corresponding second radiating arms 122. The plurality of second radiating arms 122 are arranged around the polarization center to form a groove-like structure, which is called a receiving groove 123. The receiving groove 123 is an open structure to facilitate the installation of the first oscillator 110, so that the first oscillator 110 can be embedded in the second oscillator 120.

[0048] In one embodiment, the plurality of second radiating arms 122 form the edge of the receiving groove 123, and the plurality of second insertion pins 1211 of the base extend from the polarization center to the corresponding second radiating arm 122, forming the sidewall of the receiving groove 123. In another embodiment, the plurality of second radiating arms 122 form the sidewall of the receiving groove 123.

[0049] Combination Figure 4 The oscillator mounting base 130 includes a base 131 and a mounting post 132 fixedly disposed on the base 131. The base 131 is used to support the second oscillator 120, and the mounting post 132 is used to mount the first oscillator 110. In one embodiment, the oscillator mounting base 130 is integrally formed from a dielectric material. Preferably, the dielectric material is a plastic or a polymer material.

[0050] Specifically, the mounting post 132 has a fixed end 1321 and a free end 1322 at its two ends. The fixed end 1321 is fixedly connected to the base 131. The size of the fixed end 1321 is smaller than the size of the base 131, so that the base 131 has a first circumferential portion 133 around the fixed end 1321. Specifically, the fixed end 1321 is connected to the front of the base 131. The cross-sectional area of ​​the fixed end 1321 is smaller than the area of ​​the front of the base 131. When the fixed end 1321 is connected to the front of the base 131, the fixed end 1321 cannot completely cover the front of the base 131, so that the front of the base 131 has a certain area margin relative to the fixed end 1321. This area margin constitutes the first circumferential portion 133.

[0051] Combination Figure 13 The second vibrator 120 is fitted into the mounting post 132 to support the second vibrator 120 on the base 131. Specifically, in conjunction with Figure 3 The second oscillator 120 has a first mounting hole 1212 on its second base 121. The first mounting hole 1212 is located at the polarization center of the second oscillator 120. The second oscillator 120 is sleeved with the mounting post 132 through its first mounting hole 1212. The second base 121 of the second oscillator 120 is connected to the first circumferential portion 133, that is, the second base 121 of the second oscillator 120 is disposed on the base 131, so that the second oscillator 120 is supported on the base 131. The free end 1322 of the mounting post 132 extends into the receiving groove 123 of the second oscillator 120 through the first mounting hole 1212. Preferably, the first mounting hole 1212 is formed by connecting a plurality of second insertion pins 1211 of the second base 121.

[0052] Combination Figure 4The base 131 is provided with a first connecting structure and a first guiding structure for fixing the second oscillator 120 on the base 131. Specifically, the first connecting structure and the first guiding structure are disposed on the first peripheral portion 133 of the base 131, and the first connecting structure and the first guiding structure are used to fix the second oscillator 120 on the first peripheral portion 133.

[0053] In one embodiment, the first connection structure includes a locking structure that cooperates with the second vibrator 120 to achieve interlocking. The locking structure includes a first insertion arm 1332, which is parallel to the mounting post 132 and located outside the mounting post 132. The first insertion arm 1332, the mounting post 132, and the base 131 surround each other to form a first insertion groove 1334. The second base 121 of the second vibrator 120 has a second insertion arm (not shown) corresponding to the first insertion groove 1334 and a second insertion groove (not shown) corresponding to the first insertion arm 1332. The first insertion arm 1332 of the locking structure is inserted into the second insertion groove of the second vibrator 120, and the second insertion arm of the second vibrator 120 is inserted into the first insertion groove 1334 of the locking structure. Thus, the interlocking between the second vibrator 120 and the locking structure is achieved, so that the second vibrator 120 can be fixedly supported on the first circumferential portion 133 of the base 131.

[0054] In another embodiment, combined Figure 6 The first plug-in arm 1332 has a buckle 1333 at its top end, and the second base 121 of the second vibrator 120 has a slot (not shown) corresponding to the first plug-in arm 1332. The buckle 1333 of the first plug-in arm 1332 is fastened into the slot to fix the second vibrator 120 to the first circumferential portion 133 of the base 131. Preferably, the first plug-in arm 1332 has reinforcing ribs to improve the structural strength of the first plug-in arm 1332.

[0055] In one embodiment, combined Figure 4 The first guide structure includes a plurality of first positioning posts 1331 disposed on the front side of the base 131, combined with Figure 3 The second base 121 of the second oscillator 120 is provided with a plurality of first positioning holes 1213 corresponding to the plurality of first positioning posts 1331. The plurality of first positioning posts 1331 of the first guide structure are inserted into the plurality of first positioning holes 1213 on the second base 121 to position the second oscillator 120 so that the second oscillator 120 will not move circumferentially relative to the first circumferential portion 133.

[0056] In a typical embodiment of the present invention, combined with Figure 4The mounting post 132 has a mounting platform 135 on its free end 1322. The mounting platform 135 forms a power supply mounting groove 136. The power supply mounting groove 136 is used to insert the first base 111 of the first oscillator 110 so as to install the first oscillator 110 on the power supply mounting groove 136.

[0057] Specifically, in combination Figure 7 The power supply mounting groove 136 is provided with a wiring hole 1363. The wiring hole 1363 extends from the free end 1322 of the mounting post 132 through the fixed end 1321 to the reverse side of the base 131. That is to say, the wiring hole 1363 has an opening at the bottom of the power supply mounting groove 136 and an opening on the reverse side of the base 131 to form a wiring channel, so that the external feed line can extend to the power supply mounting groove 136 through the wiring hole 1363. This allows the external feed line to be electrically connected to the first oscillator 110 in the power supply mounting groove 136 to power the first oscillator 110, avoiding the need for the external feed line to extend from the surface of the second oscillator 120 to power the first oscillator 110. Preferably, there are multiple wiring holes 1363, each corresponding to a different polarization of the radiating arm of the first oscillator 110. Each wiring hole 1363 is used to introduce an external feed line that powers the corresponding polarization of the radiating arm. The external feed line is preferably a coaxial cable.

[0058] In one embodiment, combined with Figure 2 The first base 111 of the first oscillator 110 has multiple first pins 1111 that are baluns. An external feed line introduced through the wiring hole 1363 is physically connected to the multiple baluns to power the first oscillator 110 via the baluns.

[0059] Combination Figure 4 The power supply mounting slot 136 is further provided with multiple limiting clips 1361, which are used to engage with multiple first plug pins 1111 of the first base 111 of the first vibrator 110 to fix the multiple first plug pins 1111, so that the first vibrator 110 is stably inserted into the power supply mounting slot 136. Figure 8The limiting bracket 1361 is disposed on the groove wall of the power supply mounting groove 136. The limiting bracket 1361 has a first limiting protrusion 1362, which is obliquely downward toward the bottom of the power supply mounting groove 136. The limiting brackets 1361 are arranged in pairs, with one pair of limiting brackets 1361 respectively disposed on both sides of the power supply mounting groove 136, so that the pair of limiting brackets 1361 are symmetrical about the central axis of the mounting post 132. A pair of limiting clips 1361 each have a first limiting protrusion 1362 disposed opposite to each other. One or more first plug pins 1111 are disposed between the first limiting protrusions 1362 of the pair of limiting clips 1361. The pair of first limiting protrusions 1362 limit the one or more first plug pins 1111 disposed therebetween, thereby fixing the first oscillator 110 by fixing the first plug pins 1111, so that the first oscillator 110 is stably disposed in the receiving groove 123 of the second oscillator 120 through the oscillator mounting base 130. Preferably, each pair of limiting clips 1361 limits multiple first plug pins 1111 belonging to the same polarization.

[0060] In one embodiment, combined Figure 7 The power supply mounting groove 136 is also provided with a plurality of plug holes 1364, and the plurality of first plug pins 1111 of the first vibrator 110 are respectively plugged into the plurality of plug holes 1364 to fix the first vibrator 110.

[0061] In a typical embodiment of the present invention, combined with Figure 9 The antenna assembly 100 further includes a first reflector 150, which serves as a reflector for the first vibrator 110. The first reflector 150 is disposed on the free end 1322 of the mounting post 132 and is located below the first vibrator 110.

[0062] Specifically, in combination Figure 4 The mounting platform 135 protrudes from the free end 1322, and the cross-sectional area of ​​the mounting platform 135 is smaller than that of the free end 1322. That is to say, the mounting platform 135 cannot completely cover the free end 1322, so that the free end 1322 has a certain amount of space relative to the mounting platform 135. This amount of space constitutes the second peripheral portion 137, which is used to support the first reflector 150.

[0063] Combination Figure 9 and Figure 10The first reflector 150 is provided with a second mounting hole 151 corresponding to the mounting platform 135. The first reflector 150 is fitted into the mounting platform 135 through the second mounting hole 151 so that the first reflector 150 can be supported on the second peripheral portion 137. In order to fix the first reflector 150 on the second peripheral portion 137, the free end 1322 is provided with a second connecting structure and / or a second guiding structure for fixing the first reflector 150.

[0064] In one embodiment, combined Figure 4 The second guide structure includes a plurality of second positioning posts 1371 disposed on the second peripheral portion 137, combined with Figure 9 The first reflector 150 is provided with a plurality of second positioning holes 152 corresponding to the plurality of second positioning posts 1371, in combination with Figure 10 The second positioning post 1371 is inserted into the second positioning hole 152 to position the first reflector 150.

[0065] In one embodiment, combined Figure 11 and Figure 12 The second connection structure includes a plurality of limiting slots 1372 disposed on the free end 1322. Each limiting slot 1372 is formed by a second limiting protrusion 1373 and a second circumferential portion 137 disposed on the outer side of the mounting platform 135. The second limiting protrusion 1373 extends obliquely downward toward the second circumferential portion 137, thereby forming a limiting slot 1372 on the outer side of the mounting platform 135. Figure 10 When the first reflector 150 is sleeved on the mounting platform 135, the second mounting hole 151 of the first reflector 150 allows the first reflector 150 to smoothly slide past the second limiting protrusion 1373 as it moves from the top of the mounting platform 135 to the second peripheral edge 137 at the bottom of the mounting platform 135. However, when the first reflector 150 needs to move from the second peripheral edge 137 to the top of the mounting platform 135, it will be blocked and limited by the second limiting protrusion 1373, preventing the first reflector 150 from coming out of the limiting slot 1372, thus limiting the first reflector 150.

[0066] In a typical embodiment of the present invention, combined with Figure 14 and Figure 15 The oscillator mounting base 130 is mounted on the outer base plate 160. The base 131 of the oscillator mounting base 130 is provided with an assembly structure for assembling with the outer base plate 160. This assembly structure secures the oscillator mounting base 130 to the outer base plate 160. Preferably, the base plate is the reflector of the second oscillator 120. The elastic clip 139 is disposed on the reverse side of the base 131.

[0067] In one embodiment, combined Figure 6 and Figure 16 The assembly structure includes multiple elastic clips 139, which are disposed on the base 131. Each elastic clip 139 is U-shaped, with one end connected to the base 131 and the other end having a limiting groove 1391. Figure 14 The outer base plate 160 has multiple third mounting holes 161 corresponding to the multiple elastic clips 139. The elastic clips 139 are disposed in the third mounting holes 161, and the limiting grooves 1391 on the elastic clips 139 abut against the hole walls of the third mounting holes 161. The elastic clips 139 are compressed by the third mounting holes 161, causing the elastic clips 139 to be in a compressed state. This gives the elastic clips 139 an elastic force that extends toward the hole walls of the third mounting holes 161, allowing the elastic clips 139 to be fixed in the third mounting holes 161 by the elastic force. This, in turn, allows the vibrator mounting base 130 to be fixed on the outer base plate 160.

[0068] In one embodiment, combined Figure 16 The limiting groove 1391 has a V-shaped structure formed by the first limiting wall 1392 and the second limiting arm. The two limiting walls of the limiting groove 1391 abut against the wall of the third mounting hole 161 and the front or back of the outer base plate 160, respectively, to achieve fixation. Preferably, the first limiting wall 1392 and the second limiting wall 1393 are perpendicular to each other.

[0069] In one embodiment, an isolation platform (not shown) is further provided on the base of the second oscillator 120, extending from the second base 121 towards the outer base plate 160. The isolation platform separates the second oscillator 120 from the outer base plate 160, increasing the distance between the second base 121 of the second oscillator 120 and the outer base plate 160, reducing the coupling effect between them, decreasing the coupling current, improving the cross-polarization of the second oscillator 120, and increasing the gain of the second oscillator 120. Preferably, the height of the isolation platform is 0.05λ-0.1λ of the frequency band of the operating signal of the second oscillator 120. In one embodiment, the isolation platform is integrally formed with the aforementioned support platform 127.

[0070] In one embodiment, combined Figure 3The second oscillator 120 includes multiple pairs of radiating arms, which extend along different polarization directions. In one embodiment, the second oscillator 120 has two dipoles 129 and two feeding components 1211 feeding the two dipoles respectively in the same polarization direction. One end of each of the two feeding components 1211 is electrically connected to its corresponding dipole, and the other end of each is combined through the same physical combining port 1291 inherent in the second oscillator 120. Each dipole 129 is composed of a pair of adjacent radiating arms 122.

[0071] In one embodiment, the base 131 of the oscillator mounting seat 130 is further provided with a plurality of through holes 1311, which are used to introduce external feed lines, which are used to connect to the second base 121 of the second oscillator 120 to power the second oscillator 120.

[0072] The outer base plate 160 has a connecting hole 162 corresponding to the through hole 1311 on the base 131. The connecting hole 162 is used to introduce an external feed line into the through hole 1311 on the base 131, so that the external feed line can be electrically connected to the second base 121 of the second vibrator 120 through the connecting hole 162 and the through hole 1311. The outer base plate 160 is also provided with a fourth positioning hole 164, which is used to connect to the positioning pin on the second base 121 of the second vibrator 120, or to be threaded to the second base of the second vibrator 120 through the fourth positioning hole 164.

[0073] In one embodiment, the outer base plate 160 is further provided with a fourth mounting hole 163, which corresponds to the wiring hole 1363 on the vibrator mounting base 130, so that the external feed line can supply power to the first vibrator 110 through the fourth mounting hole 163 and the wiring hole 1363.

[0074] The present invention also provides an antenna, the antenna including the antenna assembly described above, the antenna assembly being disposed on the external base plate.
