Fig. 1 (a) shows a schematic structural diagram of an antenna system of a compact electronic device according to an embodiment of the present application. As shown in fig. 1 (a), the antenna system 100 includes at least one power divider 101, and one end of the power divider 101 is connected to at least two antennas 102 through a cable, and the other end is connected to the cable and is configured as a feed port of the antenna system 100. In an example of transmission, after the power divider 101 receives a signal from the feed port, the received signal is transmitted to the antenna 102 through the cable and the power divider 101, so that the power divider 101 and the antenna 102 are debugged as a whole, and the radio frequency performance of the whole antenna system 100 is adjusted.
Wherein the number of the power splitters 101 is matched with the number of the antennas 102. As shown in fig. 1 (c), in the case where the antenna system 100 includes three antennas, that is, antenna No. 1 102a, antenna No. 2 102b, and antenna No. 3 102c, the antenna system 100 may be configured with power splitters No. 1 101a and power splitter No. 2 101b, and the power splitters No. 1 101a and No. 2 101b may be connected in a cascade manner. Taking the example that the antenna No. 1 102a and the antenna No. 2 102b receive signals and then transmit the signals to the power divider No. 2 101b, the antenna No. 1 102a and the antenna No. 2 102b transmit the signals to the power divider No. 1 101a through cables, the power divider No. 1a transmits the signals to the power divider No. 2 101b in cascade connection through cables, meanwhile, the power divider No. 2 101b receives the signals transmitted by the antenna No. 3 102c, and the power divider No. 2 101b transmits the received total signals to the network card end through cables, which is only taken as an exemplary illustration, and the specific limitation of the cascade connection mode of the power dividers No. 1a and No. 2 101b is not formed. Specifically, the antenna No. 1 102a, the antenna No. 2 102b, and the antenna No. 3 102c may have different types or support different operating frequency bands, and the antenna No. 1 102a, the antenna No. 2 102b, and the antenna No. 3 102c are not particularly limited.
As shown in fig. 1 (b), the power divider 101 includes a substrate 103, at least two characteristic impedance transformers 104 having different characteristic impedances are disposed on the substrate 103, each characteristic impedance transformer 104 includes a first component 105 and a second component 106 that are symmetrical to each other, and each characteristic impedance transformer 104 is in the same horizontal plane and has the same symmetry axis (for example, longitudinal symmetry axis). The number of the characteristic impedance transformers 104 may be plural, and the number of the characteristic impedance transformers 104 and the characteristic impedance may be adjusted according to the operating frequency band of the antenna 102. The characteristic impedance of each characteristic impedance transformer 104 is different, and each characteristic impedance transformer 104 has a first part 105 and a second part 106 as shown in fig. 1 (b). Each of the characteristic impedance transformers 104 is in the same horizontal plane and has the same longitudinal symmetry axis, and each of the characteristic impedance transformers 104 is not arranged in a cross-stack.
Specifically, the first parts 105 of the characteristic impedance transformers 104 are connected in series, and one end of the first part 105 near the antenna 102 is connected to a first cable 107. The second members 106 of the characteristic impedance transformers 104 are connected in series, and one end of the second member 106 near the antenna 102 is connected to a second cable 108. The first component 105 and the second component 106 on the side far from the antenna 102 have the same first connection part 109, and the first connection part 109 is connected with the third cable 110 and serves as a feed port of the antenna system 100, and the feed port is used for connecting with a network card on the system side of the compact electronic device. Specifically, with the receiving example, the antenna 102 receives signals and then transmits the signals to the power divider 101, and a signal received from one of the antennas 102 is transmitted to the first section 105 of the power divider 101 on the side close to the antenna 102 via the first cable 107. Similarly, a signal received from the other of the antennas 102 is transmitted via a second cable 108 to a second component 106 of the power divider 101 on the side closer to the antenna 102. Finally, the signals transmitted via the first cable 107 and the second cable 108 are both transmitted to the first connection portion 109 on the side away from the antenna 102, and are transmitted to the network card via the third cable 110 through the first connection portion 109. Under the action of the characteristic impedance converters 104 with different characteristic impedances, the bandwidth can be effectively widened to support the working frequency bands of different antennas 102. Specifically, the implementation of the characteristic impedance transformer 104 is not particularly limited, and may be designed by microstrip lines having different characteristic impedances, for example.
Therefore, by introducing the power divider 101 and connecting the plurality of antennas 102, the patterns of different antennas 102 are complemented, so that far-field dead zones of products are reduced, and wireless internet surfing use experience of users is improved. The antenna system 100 provided in this embodiment is used as a separate component, and does not need support of system software and hardware, and can directly replace the existing antenna system. For example, the power divider 101 combines the received signals of the multiple antennas 102, inputs the combined signals to the receiving end of the radio frequency module (network card), and after introducing the multiple antennas 102, the coverage of wireless signals of the electronic device is increased, so that the problem of signal blind areas can be solved.
In some embodiments of the present application, a second connection portion 112 is fixedly connected to one end of the first member 105 near the antenna 102, and the second connection portion 112 is connected to the first cable 107; a third connecting portion 113 is fixedly connected to one end of the second component 106 near the antenna 102, and the third connecting portion 113 is connected to the second cable 108. The first connection portion 109, the second connection portion 112, and the third connection portion 113 may be cables or other components capable of transmitting signals, which are not limited in particular. Further, the first connection portion 109, the second connection portion 112 and the third connection portion 113 may be cables having characteristic impedance, and preferably, the first connection portion 109, the second connection portion 112 and the third connection portion 113 are all microstrip lines having characteristic impedance of 50 ohms.
In some embodiments of the present application, isolation resistors 111 are provided at positions where the distance between the first and second members 105 and 106 is smaller than a threshold distance, so as to avoid mutual interference of signals between the respective antennas 102. The threshold distance is not particularly limited, and may be set by the user according to experience.
In some embodiments of the present application, as shown in fig. 2, the power divider 101 includes a metal housing 201 for wrapping the substrate 103, and a metal reference ground 202 disposed on the substrate 103, where the metal reference ground 202 and the metal housing 201 are connected together by welding or a snap-fit manner. The substrate 103 of the power divider 101 is provided with a characteristic impedance transformer 104, one side of the wiring is wrapped by a metal shell 201, and the other side of the wiring is fully covered with a metal reference ground 202, wherein the metal shell 201 is connected with the metal reference ground 202 at the other side in a welding or fastening mode, so that signal leakage transmitted by the power divider 101 is avoided, and interference of external signals on normal operation of the power divider 101 is avoided.
In some embodiments of the present application, the first cable 107, the second cable 108 and the third cable 110 are fixedly connected to the second connection portion 112, the third connection portion 113 and the first connection portion 109 respectively through the through holes 203 on one side of the metal reference ground 202. The inventor of the present application found that the first cable 107, the second cable 108 and the third cable 110 are all connected to the characteristic impedance transformer 104 through the through hole 203 at one side of the metal reference ground 202, so that the internal impedance transformation of the power divider 101 can be continuous, thereby providing a wider frequency band for the power divider 101, and supporting the antennas 102 with different working frequency bands, so as to solve the problem of blind areas of the antennas 102.
In some embodiments of the present application, the at least two characteristic impedance transformers 104 include a first characteristic impedance transformer near the antenna 102 and a second characteristic impedance transformer far away from the antenna 102, where the first characteristic impedance transformer and the second characteristic impedance transformer are both obtained through arc processing, and a curved concave portion is formed at the interconnection between the first characteristic impedance transformer and the second characteristic impedance transformer. Setting the respective corners of the first characteristic impedance transformer and the second characteristic impedance transformer to circular arc angles can improve the performance of the entire antenna system 100. The smaller size of the antenna system 100 of the present application is advantageous for sustainable mass production of compact electronic devices because the existing compact electronic devices require the antenna system 100 to have smaller dimensions.
According to the antenna system 100 provided by the embodiment of the application, two characteristic impedance transformers 104 are arranged on the substrate 103 of the power divider 101, namely, a first characteristic impedance transformer close to one side of the antenna 102 and a second characteristic impedance transformer far away from the side of the antenna 102, so that the space of the power divider 101 can be fully utilized, the antenna system 100 with a smaller size can be obtained, and the working frequency band supporting the antenna 102 can be realized.
Specifically, a curved recess is formed at the interconnection of the first and second characteristic impedance transformers, and an isolation resistor 111 is provided at a position where the distance between the recess on the first part 105 side of the power divider 101 and the recess on the second part 106 side of the power divider 101 is smaller than a threshold distance, so that the performance of the entire antenna system 100 can be improved.
In addition, in the case where the characteristic impedance transformer 104 includes a first characteristic impedance transformer on the side close to the antenna 102 and a second characteristic impedance transformer on the side far from the antenna 102, the characteristic impedance of the first characteristic impedance transformer is different from the characteristic impedance of the second characteristic impedance transformer, and in this case, the power divider 101 is a two-stage power divider. The magnitudes of the characteristic impedances of the first characteristic impedance transformer and the second characteristic impedance transformer are not particularly limited, and may be adjusted according to the operating bandwidth of the antenna 102 that is matched with the power divider 101.
In some embodiments of the present application, the antenna 102 includes a first antenna and a second antenna, which are connected to the first characteristic impedance transformer through a second connection 112 and a third connection 113 on the power divider 101 via a first cable 107 and a second cable 108, respectively. For example, if the frequency band corresponding to the signal blind area of the electronic device is a low frequency band, the first antenna or the second antenna may support only the low frequency band, and the power divider 101 corresponding to the designs of the first antenna and the second antenna is matched with the first antenna and the second antenna, so that the power divider 101 can support the working frequency bands supported by the first antenna and the second antenna.
For the signal blind area angle of the electronic equipment, only the antenna 102 with a corresponding frequency band is added at a corresponding angle position after the power divider 101 is added, and the antenna can only support low frequency or high frequency. According to the previous test results, the blind area of the antenna system 100 may be a certain frequency point (single frequency antenna) instead of a full frequency band, so that the first antenna and/or the second antenna placed does not need a full frequency band, and only the antenna 102 corresponding to the blind area, such as a single frequency antenna, needs to be placed, and the size of the antenna system 100 can be made small, which reduces the volume of the antenna system 100 and the cost of the solution of the problem of the blind area.
In some embodiments of the present application, the types of the first antenna and the second antenna are different, or the frequency bands supportable by the first antenna and the second antenna are different. The types of antennas 102 connected to the power divider 101 are various, the frequency bands supported by the various antennas 102 are also various, and the power divider 101 combines them together to complement the patterns or frequency bands of the different antennas 102. By adding the power divider 101, antennas 102 with different forms or different frequency bands can be integrated together, design approaches of the antenna system 100 are diversified, and design difficulty of the antenna system 100 is reduced.
In addition, the input and output ports of the power divider 101 may be reciprocal, which means that after the power divider 101 is added, the high frequency and the low frequency of the antenna system 100 may be separately designed, and then the high frequency and the low frequency signals are converged together by the power divider 101 and input to the network card end, which increases the flexibility of the design of the antenna system 100. As described above, antenna 102 may be a single frequency antenna, making antenna system 100 smaller in size and more suitable for compact electronic devices. The compact electronic equipment can be electronic equipment such as a notebook computer, a tablet computer, a mobile phone and the like.
Based on simulation environment, simulation test is performed on the antenna system 100 according to each embodiment of the application, and the result shows that far-field pattern of the antenna system 100 is obviously improved, so that the problem of blind areas of the existing antenna can be solved.
In some embodiments of the present application, a method for adjusting an antenna frequency band may be further provided, where an end of the power divider 101 on a side far away from the antenna 102 is used as a feed port of the antenna system 100, and the power divider 101 and the antenna 102 are initially debugged as a whole, so that received signal strengths of the first antenna and the second antenna are added, and finally, a three-dimensional field pattern diagram of the antenna system 100 has no obvious blind area. After the initial commissioning, the specific location of the antenna 102 is fine tuned so that the antenna system 100 does not negatively affect the operation of the compact electronic device.
Fig. 3 is a schematic structural diagram of a part of a complete machine of a notebook computer, which is cut off by about 120mm from an antenna according to an embodiment of the application. The notebook computer 300 includes a display end (not shown) and a system end (not shown), and further includes an antenna system 301 of the compact electronic device according to various embodiments of the present application. The notebook computer 300 designed based on the antenna system 301 of the compact electronic device can solve the problem of blind areas under the condition that the antenna does not obtain a superior placement position, and improves the use experience of wireless surfing of users.
