Description

Technical Field

[0001] This utility model relates to the field of antenna structure technology, specifically to a single-pole / dual-pole integrated antenna structure. Background Technology

[0002] With the rapid development of wireless communication and electronic technology, various antenna structures have been widely used in mobile phones, wireless network devices, and Bluetooth-enabled speakers and headphones. Commonly used antennas include monopole antennas and dipole antennas.

[0003] Existing monopole and dipole antennas are generally independent structures. Monopole antennas are high-impedance antennas with high sensitivity in the open-circuit state; dipole antennas are resonant antennas, easy to set the bandwidth, and have strong anti-interference. However, due to the limited functionality of existing monopole and dipole antennas, when corresponding performance is required, only the corresponding antenna can be purchased. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a monopole and dual-pole integrated antenna structure, which integrates the structures of a monopole antenna and a dual-pole antenna, allowing for the free selection of either monopole or dual-pole antenna functions, enabling the antenna to be used as either a monopole or dual-pole antenna.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A monopole / dualpole integrated antenna structure includes a dielectric substrate and a first external electrode and a second external electrode disposed on the dielectric substrate. The dielectric substrate has a first surface, on which a first monopole signal receiving and transmitting area and a first dualpole signal receiving and transmitting area are disposed. A first metal line is disposed on the first monopole signal receiving and transmitting area, and the first metal line is electrically connected only to the first external electrode. A first metal electrode and a second metal electrode are disposed at intervals on the first dualpole signal receiving and transmitting area, the first metal electrode being electrically connected only to the first external electrode, and the second metal electrode being electrically connected only to the second external electrode.

[0006] By setting a first surface on a dielectric substrate, and setting a first monopole signal receiving and transmitting area and a first bipole signal receiving and transmitting area on the first surface, setting a first metal line on the first monopole signal receiving and transmitting area, and setting a first metal electrode and a second metal electrode at intervals on the first bipole signal receiving and transmitting area, the first metal line is electrically connected only to the first external electrode, the first metal electrode is electrically connected only to the first external electrode, and the second metal electrode is electrically connected only to the second external electrode. The first external electrode and the first metal line constitute a monopole antenna; the first external electrode, the first metal electrode, the second metal electrode, and the second external electrode constitute a bipole antenna. Thus, the structure of a monopole antenna and a bipole antenna is integrated on the same dielectric substrate, and the monopole or bipole antenna function can be freely selected, so that the antenna can be used as either a monopole or a bipole antenna.

[0007] As a preferred embodiment, the dielectric substrate further comprises a second surface, the second surface being provided with a second unipolar signal receiving and transmitting area and a second bipolar signal receiving and transmitting area, the second unipolar signal receiving and transmitting area being provided with a second metal line, the second metal line being electrically connected only to the second external electrode, the second bipolar signal receiving and transmitting area being provided with a third metal electrode and a fourth metal electrode spaced apart, the third metal electrode being electrically connected only to the second external electrode, and the fourth metal electrode being electrically connected only to the first external electrode.

[0008] As a preferred embodiment, the first metal line and the second metal line are arranged symmetrically about the center of the dielectric substrate, the first metal electrode and the third metal electrode are arranged symmetrically about the center of the dielectric substrate, and the second metal electrode and the fourth metal electrode are arranged symmetrically about the center of the dielectric substrate.

[0009] As a preferred embodiment, the first surface and the second surface are respectively disposed on opposite sides of the dielectric substrate.

[0010] As a preferred embodiment, the width of the first metal electrode is different from the width of the second metal electrode.

[0011] As a preferred embodiment, the width of the first metal electrode is smaller than the width of the second metal electrode, and the first metal electrode is disposed on the side of the second metal electrode away from the first metal wire.

[0012] As a preferred embodiment, the first metal wire is arranged in a snake shape.

[0013] As a preferred embodiment, the first metal wire comprises multiple horizontal metal segments and vertical metal segments formed by bending, with the multiple horizontal metal segments and vertical metal segments connected end to end in sequence.

[0014] As a preferred embodiment, the first unipolar signal receiving and transmitting area and the first bipolar signal receiving and transmitting area are arranged side by side along the width direction of the dielectric substrate.

[0015] As a preferred embodiment, the first external electrode is disposed at one end of the length direction of the dielectric substrate, and the second external electrode is disposed at the other end of the length direction of the dielectric substrate.

[0016] Compared with the prior art, this invention has significant advantages and beneficial effects. Specifically, by setting a first surface on a dielectric substrate, setting a first monopole signal receiving and transmitting area and a first bipole signal receiving and transmitting area on the first surface, setting a first metal line on the first monopole signal receiving and transmitting area, and setting a first metal electrode and a second metal electrode at intervals on the first bipole signal receiving and transmitting area, the first metal line is electrically connected only to the first external electrode, the first metal electrode is electrically connected only to the first external electrode, and the second metal electrode is electrically connected only to the second external electrode. The first external electrode and the first metal line constitute a monopole antenna; the first external electrode, the first metal electrode, the second metal electrode, and the second external electrode constitute a bipole antenna. Thus, the structure of a monopole antenna and a bipole antenna is integrated on the same dielectric substrate, and the function of a monopole or bipole antenna can be freely selected, so that the antenna can be used as either a monopole or a bipole antenna.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 2 As shown, for ease of description and understanding, the reference numeral X indicates the length direction of the dielectric substrate 10, and the reference numeral Y indicates the width direction of the dielectric substrate 10.

[0023] like Figure 1-3 As shown, this utility model discloses a single-pole and dual-pole integrated antenna structure. In the first embodiment, the single-pole and dual-pole integrated antenna structure includes a dielectric substrate 10, and a first external electrode 11 and a second external electrode 12 disposed on the dielectric substrate 10. Specifically, the first external electrode 11 is disposed at one end of the length direction of the dielectric substrate 10, and the second external electrode 12 is disposed at the other end of the length direction of the dielectric substrate 10.

[0024] The dielectric substrate 10 has a first surface 101, on which a first unipolar signal receiving and transmitting area 20 and a first bipolar signal receiving and transmitting area 30 are provided. The first unipolar signal receiving and transmitting area 20 and the first bipolar signal receiving and transmitting area 30 are arranged side by side along the width direction of the dielectric substrate 10. The first unipolar signal receiving and transmitting area 20 has a first metal line 21, which is electrically connected only to the first external electrode 11. The first bipolar signal receiving and transmitting area 30 has a first metal electrode 31 and a second metal electrode 32 spaced apart. The first metal electrode 31 is electrically connected only to the first external electrode 11, and the second metal electrode 32 is electrically connected only to the second external electrode 12.

[0025] The dielectric substrate 10 is further provided with a second surface 102, on which a second monopole signal receiving and transmitting area 40 and a second bipole signal receiving and transmitting area 50 are provided. A second metal line 41 is provided on the second monopole signal receiving and transmitting area 40, and the second metal line 41 is electrically connected only to the second external electrode 12. A third metal electrode 51 and a fourth metal electrode 52 are provided at intervals on the second bipole signal receiving and transmitting area 50. The third metal electrode 51 is electrically connected only to the second external electrode 12, and the fourth metal electrode 52 is electrically connected only to the first external electrode 11. By providing a second surface 102 on the dielectric substrate 10 and providing a second monopole signal receiving and transmitting area 40 and a second bipole signal receiving and transmitting area 50 on the second surface 102, more monopole antennas and bipole antennas can be arranged in the space of the dielectric substrate 10, thereby improving the performance of the antenna.

[0026] The first metal line 21 and the second metal line 41 are arranged symmetrically about the center of the dielectric substrate 10, the first metal electrode 31 and the third metal electrode 51 are arranged symmetrically about the center of the dielectric substrate 10, and the second metal electrode 32 and the fourth metal electrode 52 are arranged symmetrically about the center of the dielectric substrate 10. By adopting a symmetrical arrangement structure, the antenna will not be installed backwards, and there is no need to distinguish the direction when installing the antenna, making installation convenient.

[0027] The first surface 101 and the second surface 102 are respectively disposed on opposite sides of the dielectric substrate 10. Specifically, the first surface 101 is disposed on the front side of the dielectric substrate 10, and the second surface 102 is disposed on the back side of the dielectric substrate 10.

[0028] The dielectric substrate 10 has a protective layer 103 on both its front and back sides. The protective layer 103 on the front side of the dielectric substrate 10 covers the first metal line 21, the first metal electrode 31, and the second metal electrode 32. The protective layer 103 on the back side of the dielectric substrate 10 covers the second metal line 41, the third metal electrode 51, and the fourth metal electrode 52. A mark 104 is provided on the outer surface of the protective layer 103 on the front side of the dielectric substrate 10 near the first external electrode 11.

[0029] The width of the first metal electrode 31 is different from the width of the second metal electrode 32. Specifically, the width of the first metal electrode 31 is smaller than the width of the second metal electrode 32, and the first metal electrode 31 is disposed on the side of the second metal electrode 32 away from the first metal line 21.

[0030] Both the first metal line 21 and the second metal line 41 are arranged in a snake shape. Both the first metal line 21 and the second metal line 41 include multiple horizontal metal segments 211 and vertical metal segments 212 formed by bending. The multiple horizontal metal segments 211 and vertical metal segments 212 are connected end to end in sequence. Specifically, the horizontal metal segments 211 extend along the length direction of the dielectric substrate 10, and the vertical metal segments 212 extend along the width direction of the dielectric substrate 10. The length of the horizontal metal segments 211 is greater than the length of the vertical metal segments 212.

[0031] like Figure 4-5 As shown, in the second embodiment, the difference from the first embodiment is that the length of the transverse metal segment 211 is less than the length of the longitudinal metal segment 212.

[0032] It should be noted that the first metal wire 21 can also be arranged in a vortex shape.

[0033] It should also be noted that this utility model can be used as a monopole antenna or as a dipole antenna; the front monopole antenna and dipole antenna can be used alone, or the front and back monopole antennas and dipole antennas can be used simultaneously.

[0034] In summary, this invention integrates a monopole antenna and a bipole antenna on the same dielectric substrate 10 by providing a first surface 101 on the first surface 101, providing a first monopole signal receiving and transmitting area 20 and a first bipole signal receiving and transmitting area 30 on the first surface 101, providing a first metal line 21 on the first monopole signal receiving and transmitting area 20, and providing a first metal electrode 31 and a second metal electrode 32 at intervals on the first bipole signal receiving and transmitting area 30. The first metal line 21 is electrically connected only to the first external electrode 11, the first metal electrode 31 is electrically connected only to the first external electrode 11, and the second metal electrode 32 is electrically connected only to the second external electrode 12. The first external electrode 11 and the first metal line 21 constitute a monopole antenna; the first external electrode 11, the first metal electrode 31, the second metal electrode 32, and the second external electrode 12 constitute a bipole antenna. Thus, a monopole antenna and a bipole antenna structure are integrated on the same dielectric substrate 10, and the monopole or bipole antenna function can be freely selected, so that the antenna can be used as either a monopole or a bipole antenna.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
