Description

Technical Field

[0001] This utility model belongs to the field of communication technology, specifically relating to a CPE shipborne antenna. Background Technology

[0002] CPE, short for Customer Premise Equipment, is a device that receives mobile signals and relays them as Wi-Fi signals. It converts high-speed 4G or 5G signals into Wi-Fi signals and can support a large number of mobile devices accessing the internet simultaneously. CPEs are widely used in rural areas, towns, hospitals, workplaces, factories, and residential communities to access wireless networks, saving the cost of laying wired networks.

[0003] Currently, existing LTE base stations can only provide coverage up to 5km in the sea area, and their signals cannot cover further out to sea; the maximum spectrum bandwidth of a single cell is only 20km. Given the increasing communication needs of coastal fishermen and crew members, and the unmet requirements for high-bandwidth, low-latency, and high-reliability communication in maritime shipping routes, near-shore wind farms, marine transportation, marine engineering equipment manufacturing, cruise tourism, and port terminals, these needs cannot be met. According to the free-space transmission characteristics of electromagnetic waves, long-distance propagation leads to greater path attenuation. Taking the 2.1GHz frequency as an example, the path loss is 110dB at a coverage distance of 5km, and as high as 132dB at a coverage distance of 50km. Therefore, existing maritime communication systems suffer from high signal loss and low communication efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a CPE shipborne antenna. By arranging multiple first antenna plates side by side on the antenna mounting bracket, the electromagnetic waves radiated by the first antenna plates in the desired direction are coherently superimposed, thereby enhancing the field strength and power density of the first antenna plates in the desired direction. Furthermore, the multiple second antenna plates are arranged facing each other in the width direction of the antenna mounting bracket, thereby increasing the frequency bands supported by the CPE shipborne antenna. This increases the communication capability and anti-interference capability of the CPE shipborne antenna, allowing it to capture electromagnetic wave signals before excessive attenuation, reducing signal transmission loss, and improving communication efficiency.

[0014] In this embodiment of the application, the receiving base is further provided with a power amplifier unit, the input terminal of the power amplifier unit is electrically connected to the signal combiner board, and the output terminal of the power amplifier unit is electrically connected to the control unit.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1.

[0032] To more clearly illustrate the technical solutions in the embodiments of the present invention and the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0033] This invention provides a CPE shipborne antenna; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8It mainly includes an antenna mounting bracket 2, a first antenna board 3, and a second antenna board 4.

[0034] In this embodiment, the CPE shipborne antenna includes an antenna mounting bracket 2, a first antenna plate 3, and a second antenna plate 4. An antenna mounting part 1 is provided on the antenna mounting bracket 2. The first antenna plate 3 and the second antenna plate 4 are mounted on the antenna mounting bracket 2 and detachably connected to the antenna mounting bracket 2 via the antenna mounting part 1. Multiple first antenna plates 3 and second antenna plates 4 are provided. The first antenna plate 3 extends along the length direction of the antenna mounting bracket 2 (the length direction is...). Figure 2 The antenna plates 4 are arranged side by side in the vertical direction of the antenna mounting bracket 2. The second antenna plates 4 are located on both sides of the first antenna plate 3, and multiple second antenna plates 4 are arranged in the width direction of the antenna mounting bracket 2 (the width direction is the vertical direction of the antenna mounting bracket 2). Figure 3 The multiple second antenna panels 4 are arranged facing each other in the left-right direction (in the antenna mounting bracket 2), with their maximum radiation / reception directions precisely aligned with each other. At this point, under a given signal power, the distance between the received signal location and the second antenna panel 4 is maximized, reducing co-channel interference and improving communication efficiency. This application, by setting multiple first antenna panels 3 side-by-side on the antenna mounting bracket 2, allows the electromagnetic waves radiated by the first antenna panels 3 in the desired direction to coherently superimpose, enhancing the field strength and power density of the first antenna panels 3 in the desired direction. Furthermore, the multiple second antenna panels 4 are positioned in the width direction of the antenna mounting bracket 2 (the width direction is...). Figure 3 The antennas are arranged facing each other in the left and right directions to increase the frequency bands supported by the CPE shipborne antenna, thereby increasing the communication capability and anti-interference capability of the CPE shipborne antenna. The electromagnetic wave signal is captured before it is excessively attenuated, reducing signal loss during transmission and improving communication efficiency.

[0035] Furthermore, the antenna fixing part 1 has a threaded hole, and the first antenna plate 3 or the second antenna plate 4 is fixed to the antenna fixing bracket 2 by bolts. The first antenna plate 3 is a low-frequency antenna plate, and the second antenna plate 4 is a high-frequency antenna plate. The low-frequency support is 690 to 960 MHz, and the high-frequency support is 1700 to 2700 MHz.

[0036] When two first antenna plates 3 come into contact, the electromagnetic field of one of the first antenna plates 3 will strongly act on the adjacent first antenna plate 3, changing the current distribution on its surface. The radiation pattern of the first antenna plate 3 itself will be severely distorted by the adjacent first antenna plate 3, becoming unpredictable and usually degraded in performance (e.g., main lobe widening, side lobe lifting, null disappearance), thus causing the radiation pattern of the first antenna plate 3 to be distorted. In order to avoid the radiation pattern distortion of the first antenna plate 3, a gap is provided between the two adjacent first antenna plates 3.

[0037] Furthermore, the distance between the centers of two adjacent first antenna plates 3 is equal to 1.8 times the length of the first antenna plate 3, which avoids the radiation pattern distortion of the first antenna plate 3 and saves as much space as possible for the CPE shipborne antenna.

[0038] Specifically, there are 3 first antenna plates 3 and 2 second antenna plates 4. The 3 first antenna plates 3 are arranged side by side. The second antenna plates 4 are located on both sides of the first antenna plates 3 at the edge. The support plate is located at the end of the antenna fixing bracket 2 near the second antenna plate 4. The maximum radiation gain of the 3 first antenna plates 3 is located at the center (considering the 3 first antenna plates 3 as a whole). By setting the second antenna plate 4 at the end away from the center of the 3 first antenna plates 3 (considering the 3 first antenna plates 3 as a whole), the second antenna plate 4 is far away from the maximum radiation gain of the 3 first antenna plates 3, so as to avoid mutual interference between the first antenna plates 3 and the second antenna plates 4.

[0039] In one embodiment, the first antenna plate 3 includes a plate 31, a directing module, an antenna element 33, and a feed network 34. The directing module, antenna element 33, and feed network 34 are integrated on the plate 31. The directing module includes directing units respectively disposed on both sides of the antenna element 33. The first antenna plate 3 is provided with fixing holes. Bolts pass through the first antenna plate 3 and the antenna fixing bracket 2 and are screwed into nuts to fix the first antenna plate 3. By arranging the directing units on both sides of the antenna element 33, the radiation pattern of the antenna is made closer to a circle, improving the omnidirectionality of the detection range of the first antenna plate 3.

[0040] Furthermore, the guiding unit includes at least two directors 32 arranged side by side along the direction from the antenna unit 33 to the guiding unit. By setting two side by side guiding strips on one side of the antenna unit 33, the radiated wave is phase-shifted twice, thereby converting the spherical wave into a quasi-plane wave, compressing energy dissipation step by step, and improving the antenna gain. Moreover, the arrangement direction of the guiding strips is the same as the polarization direction of the antenna plate, thereby ensuring that the antenna and the signal source can be coupled in a limited way, thereby reducing signal attenuation.

[0041] It should be noted that the second-day line board 4 has the same structure. The antenna mounting bracket 2 is also equipped with a trapezoidal frame, which is detachably connected to the antenna mounting bracket 2. The trapezoidal frame is detachably connected to the second-day line board 4 by bolts.

[0042] Furthermore, the antenna element 33 includes a dipole, which is used to receive or transmit electromagnetic waves. The dipole is made flat to reduce the directional radiation capability of the antenna plate.

[0043] In one possible implementation, the CPE shipborne antenna also includes a support 5, which has a fixing hole on both the support 5 and the antenna mounting bracket 2. A bolt passes through the fixing hole and is screwed into a nut to achieve a detachable connection between the support 5 and the antenna mounting bracket 2.

[0044] Furthermore, the receiving base 5 is provided with a signal combiner board 6 and a control unit 7. The signal input terminal of the signal combiner board 6 is electrically connected to the first antenna board 3, and the output terminal of the signal combiner board 6 is electrically connected to the control unit 7. The control unit 7 is also electrically connected to the second antenna board 4. The control unit 7 can be one or a combination of several of the following: a central processing unit (CPU), a graphics processing unit (GPU), and a modem.

[0045] In one possible implementation, the antenna mounting bracket 2 is further provided with a bracket fixing part 8, and the CPE shipborne antenna is further provided with a fixing seat 9. The fixing seat 9 is further provided with a fixing space 91. The bracket fixing part 8 is embedded in the fixing space 91. The fixing seat 9 and the receiving seat 5 are connected by bolts. By providing the fixing seat 9, the connection between the antenna mounting bracket 2 and the receiving seat 5 is strengthened, preventing the antenna mounting bracket 2 from shaking, thereby improving the stability of the CPE shipborne antenna when operating at sea, and thus improving the signal accuracy and the stability of the signal reception process. Furthermore, the antenna mounting bracket 2 is provided with a threaded hole, and the fixing seat 9 is provided with a through hole. The bolt passes through the through hole and is screwed into the threaded hole to strengthen the connection between the fixing seat 9 and the antenna mounting bracket 2.

[0046] Furthermore, the mounting base 9 includes a mounting cylinder 92 and a reinforcing rib 93. The mounting space 91 is arranged inside the mounting cylinder 92. The mounting cylinder 92 is detachably connected to the antenna mounting bracket 2 and the receiving seat 5. The reinforcing rib 93 is arranged symmetrically along the center of the mounting base 9. By setting the reinforcing rib 93, the structural strength of the mounting base 9 is improved, and the support effect of the mounting base 9 on the antenna mounting bracket 2 is further improved.

[0047] In one possible implementation, the first antenna plate 3 and the second antenna plate 4 are arranged facing each other along the width direction of the antenna mounting bracket, so that the maximum gain directions of the first antenna plate 3 and the second antenna plate 4 are completely overlapped in space. At this time, the high-frequency narrow beam is completely embedded in the low-frequency wide beam, thereby ensuring seamless connection of the antenna's service area.

[0048] Preferably, the antenna mounting bracket 2 is also provided with a shielding rib 21. The first end of the shielding rib 21 is detachably connected to the trapezoidal frame of the second antenna plate 4, and the other end is fixedly connected to the antenna mounting bracket 2. At this time, the first antenna plate 3 is provided with a through hole through which the shielding rib 21 can pass. By setting the shielding rib 21, the distance between the two second antenna plates 4 is increased, thereby reducing the influence between the two second antenna plates 4.

[0049] In one possible implementation, a positioning module 11 is provided on the side of the antenna mounting bracket 2 away from the first antenna plate 3. The positioning module is arranged along the width direction of the antenna mounting bracket 2 on the side away from the first antenna plate 3, and the positioning module 11 is also located along the length direction of the antenna mounting bracket 2 away from the second antenna plate 4. The positioning module 11 is electrically connected to the control unit 7. By setting the positioning module 11, real-time location information is provided to the equipment to improve the route accuracy during maritime transportation. Furthermore, by arranging the positioning module 11 away from the first antenna plate 3 and the second antenna plate 4, the electromagnetic interference of the positioning module 11 to the first antenna plate 3 and the second antenna plate 4 is reduced, thereby improving the signal strength received by the first antenna plate 3 and the second antenna plate 4. Specifically, the positioning module 11 can be a GPS module that is fixed to the antenna mounting bracket 2 by bolts.

[0050] Furthermore, the positioning module 11 is located between two adjacent first antenna plates 3.

[0051] In mobile communications, due to significant differences in transmission power, antenna and RF device performance between base stations and mobile phones, the forward and reverse links are unbalanced. The robustness of the reverse link from the mobile phone to the base station is often weaker than that of the forward link from the base station to the mobile phone. Especially in 5G networks, the base station power has increased exponentially, but the mobile phone power has not increased, further reducing the uplink coverage. To address this, a power amplifier unit 12 is also installed on the receiving base 5. The input terminal of the power amplifier unit 12 is electrically connected to the output terminal of the signal combiner board 6, and the output terminal of the power amplifier unit 12 is electrically connected to the control unit 7. By installing the power amplifier unit 12 between the signal combiner board 6 and the control unit 7, the reverse link power is increased, thereby improving the communication distance and communication rate over the ocean.

[0052] Specifically, the power amplifier unit 12 can be a solid-state power amplifier, such as an LDMOS PA, or a vacuum tube power amplifier, such as a traveling wave tube amplifier.

[0053] In one possible implementation, the CPE shipborne antenna also includes a housing 10, on which an antenna receiving cavity is provided. An antenna mounting bracket 2 is arranged inside the antenna receiving cavity. Both the antenna mounting bracket 2 and the housing 10 are provided with mounting holes. The antenna mounting bracket 2 and the housing 10 are detachably connected by mounting bolts. By providing the housing 10, the antenna mounting bracket 2 and the components on the antenna mounting bracket 2 are protected, thereby improving the service life of each component.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0055] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions.
