When the antennas of terminal products such as mobile phones connected to desktop base station products (such as wireless routers) are not vertically polarized antennas but horizontally polarized antennas, polarization isolation of the transmitting and receiving antennas will occur, resulting in very poor Wi-Fi network connection performance.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0048] This application provides an adjustable polarization omnidirectional antenna. This antenna can be applied to desktop base station products such as routers, improving the quality of wireless network communication and enhancing communication performance.
[0049] refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the adjustable polarization omnidirectional antenna 100 according to an embodiment of this application. Figure 2 This is a schematic diagram of the adjustable polarization omnidirectional antenna 100 from another perspective. Figures 3 to 6 The diagrams show the structures of the first radiator 10, the second radiator 20, the third radiator 30, and the fourth radiator 40 of the adjustable polarization omnidirectional antenna.
[0050] The adjustable polarization omnidirectional antenna 100 includes a first radiator 10, a second radiator 20, a third radiator 30, and a fourth radiator 40. In practical applications, the first radiator 10, the second radiator 20, the third radiator 30, and the fourth radiator 40 can all be made of metal materials with good electrical conductivity, such as copper, aluminum alloy, and magnesium alloy.
[0051] The first radiator 10 is electrically connected to the second radiator 20. The first radiator 10 has a first hollowed-out region 111, such as... Figure 3 As shown. A second radiator 20 is disposed in the first hollow area 111, and the size of the second radiator 20 is smaller than the size of the first hollow area 111. The first hollow area 111 may form a gap. In some embodiments, the first hollow area 111 may be L-shaped.
[0052] The third radiator 30 is electrically connected to the fourth radiator 40. The fourth radiator 40 has a second hollowed-out region 411, such as... Figure 6 As shown. A third radiator 30 is disposed in the second hollow region 411, and the size of the third radiator 30 is smaller than the size of the second hollow region 411. The second hollow region 411 may form a gap. In some embodiments, the second hollow region 411 may be L-shaped.
[0053] Among them, such as Figure 1 and Figure 2 As shown, the fourth radiator 40 is positioned opposite and spaced apart from the first radiator 10, and the distance between them can be set according to actual needs.
[0054] The second radiator 20 is also electrically connected to the fourth radiator 40. The third radiator 30 is also electrically connected to the first radiator 10. The first radiator 10 is also electrically connected to the fourth radiator 40.
[0055] It should be noted that, in the embodiments of this application, "electrical connection" can be a direct connection between two electrical components or an indirect connection. For example, the electrical connection between A and B can be achieved by A and B being directly connected, or by A and B being indirectly connected through one or more other electrical components.
[0056] Furthermore, it should be noted that an electrical connection between two electrical components does not necessarily mean that they are electrically conductive. In practical applications, the electrical conductivity between two electrical components can be controlled through methods such as control circuits and control signals. When two electrical components are electrically conductive, electrical signals (such as current signals) can be transmitted between them; conversely, when two electrical components are electrically disconnected, electrical signals (such as current signals) cannot be transmitted between them.
[0057] Please refer to the above. Figure 7 , Figure 7 This is a front view of an adjustable polarization omnidirectional antenna 100 according to an embodiment of this application. The second radiator 20 and the third radiator 30 are jointly connected to a feed structure 50. The feed structure 50 is used to connect to an external feed source. Therefore, an external feed source can feed an excitation signal (e.g., a Wi-Fi excitation signal) to the antenna 100 through the feed structure 50 to excite the antenna 100 to radiate a wireless signal outward.
[0058] In this embodiment, the antenna 100 can be in different polarization states by controlling the electrical conduction state between the various radiators.
[0059] Specifically, when the second radiator 20 is electrically connected to the first radiator 10, the second radiator 20 to the fourth radiator 40, the third radiator 30 to the first radiator 10, the third radiator 30 to the fourth radiator 40, and the first radiator 10 to the fourth radiator 40, the antenna 100 is a horizontally polarized omnidirectional antenna. In this state, the antenna 100 can radiate wireless signals outward in a horizontally polarized manner. It can be understood that in this state, the first radiator 10, the second radiator 20, the third radiator 30, and the fourth radiator 40 form a single radiator, which can jointly radiate wireless signals through the gap formed by the first hollow area 111 of the first radiator 10 and the second hollow area 411 of the fourth radiator 40, thereby achieving a horizontally polarized omnidirectional coverage effect.
[0060] When the second radiator 20 is electrically disconnected from the first radiator 10, from the second radiator 20 to the fourth radiator 40, from the third radiator 30 to the first radiator 10, from the third radiator 30 to the fourth radiator 40, and from the first radiator 10 to the fourth radiator 40, the antenna 100 is a vertically polarized omnidirectional antenna. In this state, the antenna 100 can radiate wireless signals outward in a vertically polarized manner. It can be understood that in this state, the antenna 100 can radiate wireless signals through the joint radiation of the second radiator 20 and the third radiator 30, thereby achieving a vertically polarized omnidirectional coverage effect.
[0061] Therefore, the antenna 100 of this application can freely switch between horizontal and vertical polarization. In practical applications, the antenna 100 can adaptively switch according to the polarization of the antenna of the connected (wireless connected) terminal product (e.g., mobile phone, smart TV, tablet computer, etc.). For example, if the connected terminal product is a vertically polarized antenna, the antenna 100 can switch to vertically polarized antenna mode; if the connected terminal product is a horizontally polarized antenna, the antenna 100 can switch to horizontally polarized antenna mode. Therefore, the polarization of the antenna 100 of this application can remain compatible with the polarization of the antenna of the connected terminal product, thereby improving the wireless network communication quality and communication performance of the antenna 100.
[0062] In some embodiments, reference Figure 3 and Figure 6 The first radiator 10 includes a first side surface 11, a second side surface 12, a third side surface 13, and a fourth side surface 14 connected in sequence. The first hollow area 111 of the first radiator 10 is located on the first side surface 11.
[0063] The fourth radiator 40 includes a fifth side surface 41, a sixth side surface 42, a seventh side surface 43, and an eighth side surface 44 connected in sequence. The second hollow area 411 of the fourth radiator 40 is located on the fifth side surface 41.
[0064] Specifically, the first side 11 and the fifth side 41 face the same direction, the second side 12 and the sixth side 42 face the same direction, the third side 13 and the seventh side 43 face the same direction, and the fourth side 14 and the eighth side 44 face the same direction. The first side 11 and the fifth side 41, the second side 12 and the sixth side 42, the third side 13 and the seventh side 43, and the fourth side 14 and the eighth side 44 are all electrically connected.
[0065] In some embodiments, the first radiator 10 is a hollow column, such as a hollow metal column formed by a metal surface. A first opening 15 and a second opening 16 are formed at both ends of the first radiator 10 along its length. The second radiator 20 is disposed near the second opening 16.
[0066] The fourth radiator 40 is a hollow column, such as a hollow metal column formed by a metal surface. A third opening 45 and a fourth opening 46 are formed at both ends of the fourth radiator 40 along its length. The third opening 45 is opposite to and spaced from the second opening 16 of the first radiator 10. The third radiator 30 is positioned close to the third opening 45.
[0067] In some embodiments, reference Figure 4 and Figure 5 The second radiator 20 is L-shaped, for example, an L-shaped sheet made of metal. The long side end 21 of the second radiator 20 is electrically connected to the first radiator 10. The short side end 22 of the second radiator 20 is electrically connected to the power supply structure 50. The short side side 23 of the second radiator 20 is electrically connected to the fourth radiator 40.
[0068] Understandably, since the second radiator 20 is L-shaped, the width of the part of the second radiator 20 that is connected to the power supply structure 50 (i.e., end 22) is different from the width of other parts away from the connection part. Therefore, the second radiator 20 can achieve impedance matching under two polarization states (i.e., vertical polarization state and horizontal polarization state).
[0069] The third radiator 30 is L-shaped, for example, an L-shaped sheet made of metal. The long side end 31 of the third radiator 30 is electrically connected to the fourth radiator 40. The short side end 32 of the third radiator 30 is electrically connected to the power supply structure 50. The short side 33 of the third radiator 30 is electrically connected to the first radiator 10.
[0070] Similarly, since the third radiator 30 is L-shaped, the width of the part of the third radiator 30 that is connected to the feed structure 50 (i.e., end 32) is different from the width of other parts away from the connection part. Therefore, the third radiator 30 can achieve impedance matching under two polarization states (i.e., vertical polarization state and horizontal polarization state).
[0071] In some embodiments, the second radiator 20 and the third radiator 30 are arranged symmetrically about the feeding structure 50, such as... Figure 1 , Figure 2 and Figure 7 As shown.
[0072] In some embodiments, continue to refer to Figure 7 The second radiator 20 is electrically connected to the first radiator 10 via a first switching element 61. The second radiator 20 is electrically connected to the fourth radiator 40 via a second switching element 62. The third radiator 30 is electrically connected to the first radiator 10 via a third switching element 63. The third radiator 30 is electrically connected to the fourth radiator 40 via a fourth switching element 64. The first radiator 10 is electrically connected to the fourth radiator 40 via a fifth switching element 65.
[0073] In some embodiments, there may be multiple fifth switching elements 65, which are electrically connected to different locations of the first radiator 10 and the fourth radiator 40. For example, as Figure 7 As shown, a fifth switching element 65 can be provided on both sides of the first side 11 of the first radiator 10 and the fifth side 41 of the fourth radiator 40 for electrical connection.
[0074] In some embodiments, reference is also made to Figures 8 to 10 , Figures 8 to 10 These are the right view, rear view, and left view of the adjustable polarization omnidirectional antenna 100 according to an embodiment of this application.
[0075] Among them, such as Figure 8 As shown, a fifth switching element 65 can be electrically connected between the second side 12 of the first radiator 10 and the sixth side 42 of the fourth radiator 40. Figure 9 As shown, a fifth switching element 65 can be electrically connected between the third side 13 of the first radiator 10 and the seventh side 43 of the fourth radiator 40. Figure 10 As shown, a fifth switching element 65 can be provided between the fourth side 14 of the first radiator 10 and the eighth side 44 of the fourth radiator 40 for electrical connection.
[0076] Understandably, since both the first radiator 10 and the fourth radiator 40 are formed by enclosing metal surfaces, and the areas of the first radiator 10 and the fourth radiator 40 are relatively large, multiple fifth switching elements 65 are provided between the first radiator 10 and the fourth radiator 40 for electrical connection. Furthermore, the multiple fifth switching elements 65 are connected to different parts between the first radiator 10 and the fourth radiator 40, thus ensuring good electrical connection performance between the first radiator 10 and the fourth radiator 40.
[0077] In some embodiments, the first switching element 61, the second switching element 62, the third switching element 63, the fourth switching element 64, and the fifth switching element 65 all include diodes, such as PN diodes.
[0078] In this embodiment, the first radiator 10 receives a first-level signal, such as the first-level signal GPIO1. The second radiator 20 receives a second-level signal, such as the second-level signal GPIO2. The third radiator 30 receives a third-level signal, such as the third-level signal GPIO3. The fourth radiator 40 receives a fourth-level signal, such as the fourth-level signal GPIO4. The first-level signal GPIO1, the second-level signal GPIO2, the third-level signal GPIO3, and the fourth-level signal GPIO4 can all be high, medium, or low. It is understood that a high-level voltage is greater than a medium-level voltage, and a medium-level voltage is greater than a low-level voltage.
[0079] Among them, the first level signal GPIO1, the second level signal GPIO2, the third level signal GPIO3, and the fourth level signal GPIO4 are used to jointly control the electrical conduction or electrical disconnection of the first switching element 61, the second switching element 62, the third switching element 63, the fourth switching element 64, and the fifth switching element 65.
[0080] In some embodiments, when the first level signal GPIO1 is high, the second level signal GPIO2 is medium, the third level signal GPIO3 is medium, and the fourth level signal GPIO4 is low, the first switching element 61, the second switching element 62, the third switching element 63, the fourth switching element 64, and the fifth switching element 65 are all electrically turned on. In this state, the antenna 100 is a horizontally polarized omnidirectional antenna, and the antenna 100 can radiate wireless signals outward in a horizontal polarization manner.
[0081] When the first level signal GPIO1, the second level signal GPIO2, the third level signal GPIO3, and the fourth level signal GPIO4 are all low, the first switch element 61, the second switch element 62, the third switch element 63, the fourth switch element 64, and the fifth switch element 65 are all electrically disconnected. In this state, the antenna 100 is a vertically polarized omnidirectional antenna, and the antenna 100 can radiate wireless signals outward in a vertically polarized manner.
[0082] refer to Figure 11 , Figure 11 This is the radiation pattern of the adjustable polarization omnidirectional antenna 100 in the vertical polarization state according to an embodiment of this application. Curve L1 represents the vertical polarization component of the antenna 100, and curve L2 represents the horizontal polarization component of the antenna 100. Figure 11 It can be seen that when the antenna 100 is in a vertically polarized state, the vertical polarization component of the antenna 100 is dominant, thus it has good vertical polarization radiation performance.
[0083] refer to Figure 12 , Figure 12 This is the radiation pattern of the adjustable polarization omnidirectional antenna 100 in the horizontal polarization state according to an embodiment of this application. Curve L3 represents the horizontal polarization component of the antenna 100, and curve L4 represents the vertical polarization component of the antenna 100. Figure 12 It can be seen that when the antenna 100 is in a horizontal polarization state, the horizontal polarization component of the antenna 100 is dominant, thus it has good horizontal polarization radiation performance.

Figure 14 The figure shows the impedance matching characteristic curve of the adjustable polarization omnidirectional antenna 100 in the horizontal polarization state according to an embodiment of this application. As can be seen from the figure, the antenna 100 has qualified impedance matching characteristics in both the vertical polarization state and the horizontal polarization state.

Figure 16 This diagram illustrates the horizontal coverage characteristics of the adjustable polarization omnidirectional antenna 100 in a horizontally polarized state, according to an embodiment of this application. As shown in the diagram, the antenna 100 exhibits excellent horizontal coverage characteristics in both vertically and horizontally polarized states.
