[0055] See also Figures 1 to 7As shown, the antenna system 100 provided in the embodiment of the present application includes a substrate plate 101 and a chip 102. The substrate plate 101 includes a stacked liquid crystal polymer material layer 1011 and a metal layer 1012. The metal layer 1012 is integrally provided with a planar transmission line, and the planar transmission line includes a conductive line 1015, and at least one of an antenna 1013 or a feeder 1014.

[0056] The antenna system 100 provided in the embodiment of the present application has a planar transmission line integrally arranged on the metal layer 1012. As a structure formed on the metal layer 1012 within the thickness range of the metal layer 1012, it is a part of the structure of the metal layer 1012. Therefore, without increasing the thickness of the substrate plate 101, the integrated design of the antenna system 100 is realized, and there is no need to configure additional transmission devices, antenna devices or feeder devices on the substrate plate 101, which simplifies the structure of the antenna system 100 and reduces the cost of the antenna system 100. The integrated design also reduces the transmission loss and can meet the design requirements of the antenna system 100 to be lightweight.

[0057] In some embodiments, part of the metal material can be etched away along the thickness direction of the metal layer 1012, and the thickness of the etched part of the metal material can be made consistent with the thickness of the metal layer 1012 to form the above-mentioned conductive line 1015, antenna 1013 or feed line 1014, that is, the inner surface of the conductive line 1015, antenna 1013 or feed line 1014 along the thickness direction of the metal layer 1012 is in contact with the surface of the liquid crystal polymer material layer 1011.

[0058] In some embodiments, part of the metal material can be etched away along the thickness direction of the metal layer 1012, and the thickness of the etched part of the metal material can be made greater than the thickness of the metal layer 1012 to form the above-mentioned conductive line 1015, antenna 1013 or feed line 1014, that is, part of the conductive line 1015, antenna 1013 or feed line 1014 along the thickness direction is formed on the liquid crystal polymer material layer 1011, but does not penetrate the thickness of the liquid crystal polymer material layer 1011.

[0059] Among them, the forming method of the conductive line 1015, the antenna 1013 or the feed line 1014 on the substrate plate 101 includes but is not limited to an etching process, and the etching process includes but is not limited to removing unnecessary metal parts on the metal layer 1012 through chemical reaction or physical impact, and the etching depth can be greater than or equal to the thickness of the metal layer 1012), leaving the required parts to form the above-mentioned conductive line 1015, the antenna 1013 or the feed line 1014.

[0060] Among them, the liquid crystal polymer material layer 1011 may include but is not limited to the material layer collectively referred to as LCP in the existing wireless communication field. As a new type of high-performance special engineering plastic, it is composed of rigid molecular chains and belongs to aromatic thermoplastic polyester. Under certain physical conditions, it can exhibit an anisotropic state with both the fluidity of liquid and the physical properties of crystals. It has good signal transmission stability and good flexibility, and can be used to bend the antenna system 100 to obtain a shape that is compatible with the main part 201 of the wireless communication device 200 through bending.

[0061] like Figures 4 to 6 As shown, in some embodiments, the metal layer 1012 includes at least a first metal layer 1012a and a second metal layer 1012b, the liquid crystal polymer material layer 1011 is stacked between the first metal layer 1012a and the second metal layer 1012b, and the chip 102, the conductive line 1015, the antenna 1013 or the feed line 1014 are arranged on the first metal layer 1012a.

[0062] In this embodiment, the chip 102, the conductive line 1015, the antenna 1013 or the feed line 1014 are arranged on the first metal layer 1012a, that is, the chip 102, the conductive line 1015, the antenna 1013 or the feed line 1014 are arranged on the same side of the substrate plate 101, further realizing the lightweight design of the antenna system 100.

[0063] In some embodiments, a portion of the chip 102, the conductive line 1015, the antenna 1013 or the feed line 1014 may be disposed on the first metal layer 1012a, and another portion may be disposed on the second metal layer 1012b. Compared with the existing solution of assembling a module with LCP as a circuit substrate and a separate antenna structure, this embodiment arranges the chip 102, the conductive line 1015, the antenna 1013 or the feed line 1014 on both sides of the substrate plate 101, which can still make the antenna system 100 thinner and lighter.

[0064] In some embodiments, the number of metal layers 1012 may not be limited, and the number of liquid crystal polymer material layers 1011 may not be limited, as long as a liquid crystal polymer material layer 1011 is stacked between two adjacent metal layers 1012 and a metal layer 1012 is stacked between two adjacent liquid crystal polymer material layers 1011.

[0065] The chip 102 may be mounted on the first surface 1012 c of the outermost metal layer 1012 by means of SMT (Surface Mounted Technology).

[0066] The antenna 1013 or the feeder 1014 is integrally arranged on the outermost metal layer 1012. The antenna 1013 or the feeder 1014 is integrally arranged on the substrate plate 101, and is not assembled as an independent device, so as not to occupy additional design space, reduce the cross-sectional thickness of the antenna system 100, and help meet the design requirements of lightness and thinness.

[0067] In some embodiments, the pattern of the antenna 1013 includes but is not limited to a microstrip patch antenna, a microstrip dipole antenna, a microstrip traveling wave antenna, a microstrip slot antenna, etc. The antenna 1013 may include one or more antenna patterns to form an antenna unit or an antenna array. When the antenna 1013 is used as an array antenna, the antenna 1013 is composed of an antenna pattern, a feeding circuit, a phase shifting circuit, etc., that is, part of the line is used as an antenna pattern, part of the line is used as a feeding circuit, and part of the line is used as a phase shifting circuit.

[0068] The conductive line 1015 is integrally provided on the outermost metal layer 1012 and / or integrally provided on the metal layer 1012 stacked between two adjacent liquid crystal polymer material layers 1011. When the conductive line 1015 is provided on both the outermost metal layer 1012 and the metal layer 1012 stacked between two adjacent liquid crystal polymer material layers 1011, the conductive lines 1015 on different metal layers 1012 can be electrically connected, for example, through metallized interlayer holes. In some embodiments, the graphic form of the conductive line 1015 includes but is not limited to microstrip line, stripline, coplanar waveguide, substrate integrated waveguide, etc.

[0069] From a functional point of view, an antenna can be understood as a converter, which can convert the guided waves transmitted by the conductive line into electromagnetic waves propagating in free space, or perform the opposite conversion, thereby completing the transmission or reception of electromagnetic waves.

[0070] The feeder can transmit signals between different systems. The signal received by the antenna on the metal layer can be transmitted to other systems through the feeder. For example, it can be transmitted to the device antenna through electrical coupling. The coupling method of the feeder directly affects the signal reception effect and signal transmission quality between the antenna on the metal layer and the device antenna.

[0071] A conductive line refers to a linear structure that can conduct electromagnetic energy. It can conduct guided waves carrying information from one point to another along a specified route. For example, the conductive line is connected between a chip and an antenna or between an antenna and a feeder. It can conduct guided waves between the chip and an antenna or between an antenna and a feeder.

[0072] In some embodiments, the substrate plate 101 includes at least a first portion 101a and a second portion 101b, the first portion 101a and the second portion 101b are substantially plate-shaped planar structures, and an angle is formed between the first portion 101a and the second portion 101b. The first portion 101a is provided with a chip 102, and at least one of the first portion 101a and the second portion 101b is provided with at least one antenna 1013 or a feeder 1014. The plate-shaped planar structure refers to a structure having a certain planar extension area and a certain thickness, and the ratio of the planar extension area to the thickness is relatively large.

[0073] The first part 101a and the second part 101b are both parts of the substrate plate 101, and the two are connected as one. Since the substrate plate 101 has a certain flexibility and can be bent at any angle, the angle between the first part 101a and the second part 101b can be adaptively bent according to the specific part of the main part 201 of the wireless communication device 200, and the angle between the two can be an obtuse angle, a right angle or an acute angle. Moreover, the extension area of ​​the first part 101a and the second part 101b can be selected according to the specific part of the main part 201, and the extension area of ​​the first part 101a and the second part 101b can be roughly the same, or they can be greatly different.

[0074] In some embodiments, at least one antenna 1013 or feeder 1014 is provided on the first part 101a, and the feeder 1014 is used to electrically couple with the device antenna 202 on the main body 201. The antenna 1013 on the first part 101a or the device antenna 202 opposite to the first part 101a can achieve radiation in one direction, which is at an angle to the first part 101a. The second part 101b is not provided with a chip 102, an antenna 1013 or a feeder 1014. The second part 101b is only convenient for adapting to a specific part of the main body 201, which is conducive to the fitting and mounting of the antenna system 100 on the main body 201.

[0075] In some embodiments, at least one antenna 1013 or feeder 1014 is provided on the second part 101b, and the feeder 1014 is used to electrically couple with the device antenna 202 on the main part 201. The antenna 1013 on the second part 101b or the device antenna 202 opposite to the second part 101b can achieve radiation in one direction, which is at an angle to the second part 101b. The first part 101a is provided with a chip 102, and the second part 101b is provided with an antenna 1013 or feeder 1014, which is conducive to the antenna system 100 being fitted on the main part 201, while making full use of the areas of the first part 101a and the second part 101b, and the chip 102, antenna 1013 or feeder 1014 are arranged in a partitioned manner.

[0076] In some specific embodiments, a plurality of antennas 1013 or feeders 1014 are provided on the second part 101b. Exemplarily, the plurality of antennas 1013 or feeders 1014 may be sequentially spaced along a first direction, and the first direction is parallel to the intersection line of the first part 101a and the second part 101b, so as to facilitate layout of the plurality of antennas 1013 or feeders 1014 on the second part 101b to realize a multi-channel antenna system 100.

[0077] The intersection line refers to a line formed by the connection points of two parts extending continuously along one direction. In this embodiment, the two parts refer to the first part 101a and the second part 101b, and the one direction refers to the first direction.

[0078] In some specific embodiments, a plurality of antennas 1013 or feeders 1014 are provided on the second portion 101b, and the plurality of antennas 1013 or feeders 1014 can be arranged in any array according to actual needs to improve the adaptability of the antenna system 100 to different radiation requirements.

[0079] In some embodiments, at least one antenna 1013 or feeder 1014 is disposed on the first part 101a, and at least one antenna 1013 or feeder 1014 is disposed on the second part 101b. In this way, from the perspective of antenna radiation direction, the antenna 1013 on the first part 101a or the device antenna 202 opposite to the first part 101a can achieve radiation in one direction, which is at an angle to the first part 101a. The antenna 1013 on the second part 101b or the device antenna 202 opposite to the second part 101b can achieve radiation in another direction, which is at an angle to the second part 101b, and the antenna system 100 can achieve radiation in two different directions.

[0080] In addition, at least one antenna 1013 or feeder 1014 is provided on the first part 101a. Whether to specifically set the antenna 1013 or the feeder 1014 can be selected according to the specific position that fits well with the first part 101a. The antenna 1013 can be directly set on the first part 101a to achieve radiation, or the device antenna 202 can be set at the specific position that fits well with the first part 101a to make it electrically coupled with the feeder slot 1014 on the first part 101a. This increases the selectivity of setting the antenna 1013 on the first part 101a or setting the device antenna 202 at the specific position that fits well with the first part 101a, which can provide the best choice according to the specific type and specific structure of the wireless communication device 200.

[0081] Similarly, at least one antenna 1013 or feeder 1014 is provided on the second part 101b. Whether to specifically provide the antenna 1013 or the feeder 1014 can be selected according to the specific position that fits well with the second part 101b. The antenna 1013 can be directly provided on the second part 101b to realize radiation, or the device antenna 202 can be provided at the specific position that fits well with the second part 101b to be electrically coupled with the feeder 1014 on the second part 101b. This increases the selectivity of providing the antenna 1013 on the second part 101b or providing the device antenna 202 at the specific position that fits well with the second part 101b, and can provide the best selection according to the specific type and specific structure of the wireless communication device 200.

[0082] In some specific embodiments, the first part 101a and the second part 101b are both provided with antennas 1013. Alternatively, the first part 101a is provided with antennas 1013, and the second part 101b is provided with feeder lines 1014, so that the antenna system 100 can achieve radiation in two different directions.

[0083] In some embodiments, the first surface 1012c includes a connection area 1016, and the connection area 1016 is used to connect to the main body 201 of the wireless communication device 200. At least one of the first part 101a and the second part 101b is provided with at least one connection area 1016. By providing the connection area 1016, an area for fixed connection is divided from the first surface 1012c, which is conducive to conveniently assembling the antenna system 100 to the main body 201 of the wireless communication device 200, thereby improving assembly efficiency and accuracy.

[0084] In some embodiments, the substrate plate 101 includes a first portion 101a and a second portion 101b, the first portion 101a and the second portion 101b are substantially in a plate-like planar structure, an angle is formed between the first portion 101a and the second portion 101b, the first portion 101a is provided with a chip 102 and a connection area 1016, and the second portion 101b is provided with an antenna 1013 or a feeder 1014. The areas of the first portion 101a and the second portion 101b are fully utilized, the chip 102 and the connection area 1016, the antenna 1013 or the feeder 1014 are arranged in partitions, and the usable area of ​​the antenna 1013 or the feeder 1014 is maximized, so that the number or formation of the antenna 1013 or the feeder 1014 can be designed according to specific needs, so as to meet the design requirements of different wireless communication devices 200.

[0085] In some specific embodiments, the chip 102 is disposed in an area on the first portion 101a close to the second portion 101b, and the connection area 1016 is disposed in an area on the first portion 101a away from the second portion 101b. Since the chip 102 and the antenna 1013 or the chip 102 and the feeder 1014 are connected via the conductive wire 1015, and the connection area 1016 is disposed on the side of the chip 102 away from the antenna 1013 or the feeder 1014, the influence of the setting of the connection area 1016 on the conductive wire 1015 can be avoided, so that the conductive wire 1015 can transmit signals in the most convenient way.
