Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and more particularly to an antenna module and a satellite terminal. Background Technology

[0002] Since Martin Cooper invented the mobile phone in 1973, mobile communication technology has developed for nearly 50 years. Although we have now entered the era of 5G mobile communication technology, mobile networks have so far only covered approximately 50% of the population, and the covered area accounts for only 30% of the land area. In contrast, satellite networks, formed by a large number of satellites distributed in low Earth orbit, have a larger coverage area than mobile networks. Therefore, for remote areas without mobile network coverage, satellite networks are typically used, where satellite ground equipment (such as satellite terminals) access the internet via satellite network links. However, existing satellite terminals use external antennas, which affects the appearance of the satellite terminals. Summary of the Invention

[0037] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0038] In this embodiment, the antenna module includes an antenna dielectric layer; a radiator located on the antenna dielectric layer; and a feed assembly connected to the radiator for exciting the radiator to radiate two mutually perpendicular polarized waves. In other words, this embodiment can form a patch-type antenna module through the antenna dielectric layer and the radiator located on the antenna dielectric layer, allowing the antenna module to be placed inside a satellite terminal. This enables the satellite terminal to have a built-in antenna, improving both the appearance and portability of the satellite terminal. Furthermore, by generating two mutually perpendicular polarized waves, the antenna module of this embodiment can achieve circularly polarized radiation when transmitting and receiving wireless signals, improving the antenna performance of the antenna module while achieving a built-in antenna. For example, the gain of the antenna module of this embodiment is significantly improved compared to a linearly polarized antenna.

[0039] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0045] Figure 5 This is a block diagram illustrating a satellite terminal according to an exemplary embodiment. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] In related technologies, such as Figure 1 As shown, traditional satellite terminal antennas use a fixed external antenna 11, which is cylindrical in shape and can be set to a length of 100mm, a width of 15mm, and a height of 15mm. However, external antennas not only affect the appearance of satellite terminals but are also inconvenient to carry.

[0048] Based on this, this disclosure proposes an antenna module that can not only be installed inside a satellite terminal, realizing the built-in antenna of the satellite terminal, but also improve the transmission and reception performance of the built-in antenna. For example... Figure 2 As shown, the antenna module includes:

[0049] Antenna dielectric layer;

[0050] Radiator 101 is located on the antenna dielectric layer;

[0051] The power supply component 102 is connected to the radiator 101 and is used to excite the radiator 101 to radiate two mutually perpendicular polarized waves.

[0052] In this embodiment of the disclosure, the antenna module is used to transmit and receive wireless signals to enable communication between a satellite terminal equipped with the antenna module and other electronic devices. These other electronic devices include mobile devices, wearable devices, or smart home devices. For example, the antenna module can enable communication between a satellite terminal equipped with the antenna module and a smart home device. As another example, the antenna module can enable communication between a satellite device equipped with the antenna module and a wearable device.

[0053] The aforementioned antenna dielectric layer is used to carry the radiator. This antenna dielectric layer can be formed of a low-density and lightweight material. In some embodiments, the antenna dielectric layer is formed of a low-temperature co-fired ceramic (LTCC) material. Thus, the antenna dielectric layer has a low dielectric constant and low dielectric loss.

[0054] The aforementioned radiator is located on the antenna dielectric layer. In some embodiments, the radiator may be a radiating patch attached to the antenna dielectric layer, thereby enabling the antenna module to be a patch-type antenna module that can be installed inside the satellite terminal.

[0055] In this embodiment of the disclosure, the radiator can be used to transmit and receive satellite communication signals. In some embodiments, the radiator is used to transmit and receive satellite communication signals at different frequencies. For example, the radiator may include a first radiating unit and a second radiating unit, wherein the first radiating unit is used to transmit and receive satellite communication signals at a first operating frequency, and the second radiating unit is used to transmit and receive satellite communication signals at a second operating frequency.

[0056] For example, the first operating frequency of the satellite communication signal transmitted and received by the first radiating unit can be within the frequency band corresponding to L5 in the Global Positioning System (GPS) signal, that is, the first operating frequency can be between 1176.45±1.023MHz. The second operating frequency of the satellite communication signal transmitted and received by the second radiating unit can be within the frequency band corresponding to L1 in the GPS signal, that is, the second operating frequency can be between 1575.42±1.023MHz.

[0057] The shape of the radiator can be set according to the actual antenna design requirements. For example, the shape of the radiator can be square or circular, and the embodiments disclosed herein are not limited thereto.

[0058] The size of the radiator is negatively correlated with the frequency at which it transmits and receives wireless signals. The radiator may include a first radiating element and a second radiating element. In some embodiments, the size of the first radiating element is larger than the size of the second radiating element. Correspondingly, the first operating frequency of the first radiating element is lower than the second operating frequency of the second radiating element.

[0059] The aforementioned feed assembly is connected to the radiator and is used to excite the radiator to radiate two mutually perpendicular polarized waves. In other words, during the feeding process of the feed assembly, the radiator does not generate a single polarized wave, but can generate two mutually perpendicular polarized waves, thereby enabling the antenna module to form circularly polarized radiation when transmitting and receiving wireless signals, thus improving the antenna performance of the antenna module.

[0060] It should be noted that the power supply component excites the radiator to radiate two mutually perpendicular polarized waves. These two polarized waves may include a horizontally polarized wave and a vertically polarized wave, and the embodiments disclosed herein are not limited thereto.

[0061] In this embodiment, the antenna module includes an antenna dielectric layer; a radiator located on the antenna dielectric layer; and a feed assembly connected to the radiator for exciting the radiator to radiate two mutually perpendicular polarized waves. In other words, this embodiment can form a patch-type antenna module through the antenna dielectric layer and the radiator located on the antenna dielectric layer, allowing the antenna module to be placed inside a satellite terminal. This enables the satellite terminal to have a built-in antenna, improving both its appearance and portability. Furthermore, by generating two mutually perpendicular polarized waves, the antenna module in this embodiment can achieve circularly polarized radiation when transmitting and receiving wireless signals. This improves the antenna performance of the antenna module while maintaining the functionality of a built-in antenna, thus offering the advantages of an external antenna. For example, the gain of the antenna module in this embodiment is significantly improved compared to a linearly polarized antenna.

[0062] In some embodiments, such as Figure 2 As shown, the power supply assembly 102 includes:

[0063] Power supply board 1021;

[0064] Two feed vias 1022 pass through the antenna dielectric layer and the radiator 101, and are electrically connected to the feed board 1021;

[0065] One of the feed vias 1022 is used to excite the radiator 101 to radiate horizontally polarized waves; the other feed via 1022 is used to excite the radiator 101 to radiate vertically polarized waves.

[0066] The aforementioned feed board is used to transmit feed signals to enable the excitation and transmission of two mutually perpendicular polarized waves by a feed via. In some embodiments, the feed board is provided with a groove for accommodating a feed line, through which the feed signal can be transmitted to the radiator via the feed via.

[0067] In this embodiment of the present disclosure, the antenna dielectric layer may be located on the feed board, and the radiator is located on the antenna dielectric layer. Therefore, by providing feed vias on the antenna dielectric layer and the radiator, an electrical connection between the radiator and the feed board can be realized, and the feed signal on the feed board can be transmitted to the radiator.

[0068] It should be noted that the size of the feed board can be set to be larger than the size of the antenna dielectric layer; the shape of the feed board can be set to be the same as the shape of the antenna dielectric layer. For example, both the shape of the feed board and the shape of the antenna dielectric layer can be square.

[0069] The two feed vias are spaced apart, and their size and shape can be set according to actual design requirements. In some embodiments, the two feed vias may have the same or different sizes. In other embodiments, the two feed vias may have the same or different shapes. For example, both feed vias may be circular or both may be square.

[0070] In this embodiment, two feed vias can feed the radiator via a coupled feeding method, enabling one feed via to excite the radiator to radiate horizontally polarized waves and the other feed via to excite the radiator to radiate vertically polarized waves. Thus, the antenna module of this embodiment generates two mutually perpendicular polarized waves, thereby enabling the antenna module to form circularly polarized radiation when transmitting and receiving wireless signals, improving the antenna performance of the antenna module while achieving an integrated antenna.

[0071] In some embodiments, such as Figure 2 and Figure 3 As shown, the antenna module further includes:

[0072] The power distribution circuit 103 is located on the power supply board 1021 and connected to two power supply vias 1022, and is used to distribute the received power supply signal into a first signal and a second signal with equal power.

[0073] The first signal and the second signal are respectively output to the two feed vias.

[0074] In this embodiment of the disclosure, the power distribution circuit includes one input port and two output ports. The input port is used to input a power supply signal, and the two output ports are used to output a first signal and a second signal. The power of the power supply signal input to the input port is equal to the sum of the power of the first signal and the power of the second signal.

[0075] For example, the power distribution circuit may be formed by a microstrip line distributor or a stripline distributor, and the embodiments disclosed herein are not limited thereto.

[0076] In this embodiment of the disclosure, the power distribution circuit distributes the feed signal into a first signal and a second signal with equal power, so that the two feed vias can transmit the first signal and the second signal with equal power, thereby exciting horizontally polarized waves and vertically polarized waves with consistent radiation levels, and thus better forming circularly polarized radiation.

[0077] In some embodiments, such as Figure 3 As shown, the antenna module further includes:

[0078] The phase shift circuit 104 is located on the transmission line of the second signal and is used to change the phase of the second signal so that the phase of the second signal is 90 degrees different from the phase of the first signal.

[0079] In this embodiment of the disclosure, the phase shift circuit changes the phase of the second signal so that the phase of the second signal is 90 degrees different from the phase of the first signal. Thus, based on the fact that the two polarized waves are perpendicular to each other and are 90 degrees out of phase, the antenna module can form circular polarized radiation.

[0080] For example, the phase shift circuit may be formed by a dielectric phase shifter or a compressed waveguide phase shifter, and the embodiments disclosed herein are not limited thereto.

[0081] In some embodiments, such as Figure 3 As shown, the antenna module further includes:

[0082] Connector 105 connects to the power distribution circuit 103 and is disposed on opposite sides of the phase shift circuit 104 on the power supply board 1021, for transmitting the power supply signal to the power distribution circuit 103.

[0083] In this embodiment, one end of the connector is connected to a power distribution circuit, and the other end is connected to the satellite chip of the satellite terminal. Thus, the feed signal sent by the satellite chip can be transmitted to the radiator through the connector, the power distribution circuit, and the feed via, enabling the radiator to radiate satellite communication signals. The connector can be made of a flexible circuit board or a board-to-board connector; this embodiment is not limited to these methods.

[0084] It should be noted that placing the connectors and phase shift circuits on opposite sides of the feed board allows for a more rational distribution of components on the feed board, reduces the area of ​​the feed board, and consequently reduces the space occupied by the entire antenna module.

[0085] In some embodiments, such as Figure 2 and Figure 3 As shown, the antenna dielectric layer includes a first dielectric layer 100a and a second dielectric layer 100b stacked together.

[0086] The radiator 101 includes a first radiating element 1011 located between the first dielectric layer 100a and the second dielectric layer 100b and a second radiating element 1012 located on the second dielectric layer 100b.

[0087] The two feed vias 1022 pass through the first dielectric layer 100a, the second dielectric layer 100b, the first radiating element 1011, and the second radiating element 1012.

[0088] In this embodiment of the present disclosure, a first dielectric layer and a second dielectric layer are stacked, and the first dielectric layer and the second dielectric layer can be arranged in parallel, and the first dielectric layer and the second dielectric layer can be two dielectric layers of equal size and the same shape.

[0089] The aforementioned first radiating element is located between the first dielectric layer and the second dielectric layer. The first radiating element can be disposed on the first dielectric layer, and the second radiating element can be disposed on the second dielectric layer. The first and second radiating elements can be used to transmit and receive satellite communication signals at different frequencies. The first operating frequency of the first radiating element can be lower than the second operating frequency of the second radiating element.

[0090] It should be noted that the first radiation unit and the second radiation unit can be arranged in parallel, and the projection of the second radiation unit onto the first radiation unit is located on the first radiation unit.

[0091] In this embodiment, two feed vias pass through the first dielectric layer, the second dielectric layer, the first radiating element, and the second radiating element. In other words, this embodiment enables the feed board to be electrically connected to the first and second radiators located on different planes via the feed vias, thereby realizing the antenna function of the antenna module.

[0092] In this embodiment, the first dielectric layer and the second dielectric layer are stacked, the first radiating element is located between the first dielectric layer and the second dielectric layer, and the second radiating element is located between the second dielectric layers. That is, in this embodiment, both the two dielectric layers and the two radiating elements are stacked, which can reduce the size of the antenna module and improve space utilization.

[0093] In some embodiments, such as Figure 3 As shown, the first dielectric layer 100a is located between the power supply plate 1021 and the second dielectric layer 100b.

[0094] In other words, the first dielectric layer is stacked on the feed board, and the second dielectric layer is stacked on the first dielectric layer, meaning that both dielectric layers are stacked on the feed board, which can further reduce the size of the antenna module.

[0095] This disclosure also proposes a satellite terminal. For example... Figure 4 As shown, the satellite terminal includes:

[0096] Conductive middle frame 201;

[0097] As in one or more of the above embodiments, the antenna module 202 is located within the accommodating space surrounded by the conductive frame 201 and is positioned near the edge of the conductive frame 201 for establishing communication with a satellite.

[0098] In this embodiment, the conductive frame includes a conductive border disposed at the edge of the conductive frame, and the antenna module can be disposed close to the conductive border. It should be noted that the conductive border can be a frame made of metal.

[0099] The aforementioned antenna module is housed within an enclosure surrounded by a conductive frame. In other words, the satellite terminal uses a built-in antenna module to establish communication with the satellite.

[0100] The aforementioned antenna module is positioned near the edge of the conductive frame, enabling the conductive frame to simultaneously transmit and receive satellite communication signals while the antenna module is transmitting and receiving signals, thus improving the antenna's transceiver performance. Furthermore, the satellite terminal in this embodiment also includes an antenna module. This antenna module, formed by an antenna dielectric layer and a radiator located on the dielectric layer, can be a patch-type antenna module, allowing it to be housed within the satellite terminal. This enables the satellite terminal to have an internal antenna, improving both its appearance and portability. Moreover, by generating two mutually perpendicular polarized waves, the antenna module in this embodiment achieves circularly polarized radiation when transmitting and receiving wireless signals, further enhancing its antenna performance while maintaining an internal antenna configuration.

[0101] In some embodiments, such as Figure 4 As shown, the antenna module 202 is located at the connection point of two adjacent conductive sides in the conductive frame 201.

[0102] In this embodiment, the antenna module is located at the connection point of two adjacent conductive edges within the conductive frame. Thus, when the antenna module generates two mutually perpendicular polarized waves, it excites the conductive frame to generate an induced current, thereby improving the overall radiation efficiency and bandwidth of the antenna module.

[0103] It should be noted that the conductive frame includes a first conductive edge and a second conductive edge, such as... Figure 4As shown, when the antenna module generates two mutually perpendicular polarized waves, the first conductive side will generate a horizontally polarized induced current A, and the second conductive side will generate a vertically polarized induced current B. Since the radiation parameters of the horizontal and vertical polarizations are within a preset threshold range, the antenna module will generate highly pure circularly polarized radiation, thus improving the transceiver performance of the satellite terminal.

[0104] In some embodiments, such as Figure 4 As shown, the satellite terminal includes:

[0105] Printed circuit board 203;

[0106] The satellite chip 204 and the antenna module 202 are both located on the printed circuit board 203 and connected to the connector of the antenna module 202.

[0107] In this embodiment of the disclosure, the antenna module is located on the printed circuit board. When the antenna module transmits and receives satellite communication signals, it can not only excite the conductive frame to transmit and receive satellite communication signals together, but also excite the printed circuit board to transmit and receive satellite communication signals together, which can further improve the transmission and reception performance of the satellite terminal's antenna.

[0108] In some embodiments, such as Figure 4 As shown, the satellite terminal also includes:

[0109] Camera module 205;

[0110] The antenna module 202 and the camera module 205 are located on the same side of the satellite terminal.

[0111] In this embodiment, the antenna module and the camera module are located on the same side of the satellite terminal, which enables more flexible antenna module configuration.

[0112] In some embodiments, such as Figure 4 As shown, the antenna module 202 is located at the top of the satellite terminal, and the battery module 206 is located at the bottom of the satellite terminal.

[0113] In some embodiments, the distance between the antenna dielectric layer of the antenna module and the edge of the conductive frame is less than 5 mm.

[0114] In this embodiment of the disclosure, the distance between the antenna dielectric layer and the edge of the conductive frame is set to less than 5 mm, which enables the mutually perpendicular polarized waves generated by the antenna module to better excite the conductive frame to generate induced current, thereby improving antenna performance.
