Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a horizontally polarized antenna and electronic equipment. Background Technology

[0002] Existing technologies for horizontally polarized antennas still have their limitations. While using a cross-dipole structure as a series-fed dipole antenna can achieve horizontal polarization, its overall size is large, and it requires a complex feeding network to ensure phase and amplitude consistency, making it unsuitable for integration into compact devices. Antennas based on Alford ring structures, although having a lower profile and smaller footprint, making them suitable for embedded applications, have a narrower operating bandwidth, and their design and debugging processes are sensitive to parameters, making it difficult to balance bandwidth and stability. Furthermore, while some horizontally polarized antennas using planar slot structures are easy to integrate with circuit boards, their radiation patterns are easily distorted due to the limited size of the metal ground plane, especially forming "missing corners" in the edge regions, resulting in discontinuous omnidirectional coverage in the horizontal plane and affecting communication reliability. Therefore, how to expand the operating bandwidth and achieve stable and uniform omnidirectional radiation while reducing antenna size, lowering profile height, and simplifying feeding methods remains a challenge for current horizontally polarized antennas.

[0013] This invention also proposes an electronic device, including the horizontally polarized antenna described above.

[0014] The technical solution of this invention involves setting at least two dipole radiating units on a substrate and connecting them using at least two transmission lines to form a series-feed structure. This allows radio frequency signals to be transmitted sequentially to each dipole radiating unit, achieving cascaded excitation. The transmission lines employ a coplanar double-conduction structure, such as a parallel double-line transmission structure. During excitation, the current vectors on the two conductors are opposite, resulting in weak self-radiation capability. Therefore, it can serve as an efficient feeding path, fulfilling the series connection function without interfering with the main radiation field of the dipole radiating units and parasitic patches, thus ensuring the purity of the overall radiation pattern. Simultaneously, parasitic patches are set on the substrate, with both ends connected to at least two dipole radiating units via indirect electrical coupling. This coupling method allows the parasitic patches to obtain energy from the dipole radiating units, exciting a continuous ring current distribution within the target frequency. This ring current operating mode exhibits traveling wave characteristics and has a wide impedance bandwidth, suitable for the broadband performance requirements of 5G communication. By adjusting the length of the transmission line, the phase relationship between the dipole radiating elements can be controlled, achieving an ideal current distribution at center frequencies such as 5500MHz. After introducing the parasitic patch, a distinct loop current operating mode is formed at 5500MHz, with the electric field vector oscillating primarily in the horizontal direction, thus achieving horizontally polarized radiation. Simultaneously, by adjusting the width and length of the parasitic patch, impedance matching between it and the dipole radiating elements can be optimized, achieving broadband standing wave matching within the 5G band and improving radiation efficiency.

[0022] With the continuous growth of wireless communication demands and the ongoing evolution of mobile communication technology, higher requirements are being placed on the performance and reliability of communication links. Against this backdrop, innovation in antenna technology has become a key factor in improving the efficiency of electronic devices. Traditional antennas are mostly vertically polarized, but in complex and ever-changing application scenarios, relying solely on a single polarization method is insufficient to meet the demands. Therefore, the introduction of horizontally polarized antennas has gradually gained attention because it can provide a wider range of polarization matching options, effectively reducing polarization mismatch loss during signal propagation, thereby improving communication quality.

[0023] Understandably, the current development trend of horizontally polarized antennas is to achieve miniaturization and low-profile design as much as possible, and simplify the feeding structure, while ensuring good radiation performance, in order to reduce the space occupation in terminal equipment, and at the same time maintain excellent omnidirectional radiation characteristics to ensure wide signal coverage. However, existing technical solutions still have their own limitations.

[0024] In early explorations, researchers attempted to achieve built-in horizontal polarization radiation using cross-dipole structures and vertically arranged collinear arrays. These structures can achieve horizontal polarization response to some extent, but are limited by size or bandwidth, making them difficult to widely apply in compact terminal devices.

[0025] Subsequently, an antenna design based on a ring structure was proposed, which uses a ring radiator to excite an electromagnetic field, forming a radiation characteristic dominated by horizontal polarization, and initially achieving omnidirectional coverage.

[0026] With increasing performance requirements, slot antenna structures have been introduced into horizontal polarization designs due to their potential for low loss and high gain. Slot antenna structures can reduce energy loss in the medium and improve radiation efficiency. However, the radiation direction of a single slot antenna is figure-eight shaped, which cannot achieve omnidirectional coverage in the horizontal plane.

[0027] To address this issue, a multi-slot unit splicing method was subsequently adopted. Through optimization of the spatial layout, the radiation patterns of each unit compensated for each other, achieving continuous and uniform omnidirectional radiation in the horizontal plane.

[0028] Furthermore, by combining a loop antenna with a cylindrical slot structure, the slots on the hollow cylinder are excited by the ring-shaped radiator, forming a highly efficient horizontally polarized radiation mode. This structure not only broadens the operating bandwidth but also enhances the stability of omnidirectional radiation.

[0029] In recent years, to adapt to the development of miniaturized and low-profile equipment, a horizontally polarized antenna based on the Alford ring antenna structure has been proposed. This design employs a double-sided PCB process and uses symmetrical conductors on both sides to suppress electromagnetic leakage in non-radiating areas, achieving omnidirectional coverage in a compact size. Its single-point feed characteristic also facilitates integration. However, in practical applications, the coaxial cable introduced by the center feed may obstruct the surrounding radiation field, causing local distortion of the radiation pattern and affecting the integrity of the omnidirectional performance.

[0030] Therefore, how to expand the operating bandwidth and achieve stable and uniform omnidirectional radiation while reducing antenna size, lowering profile height, and simplifying feeding methods remains a challenge for current horizontally polarized antennas.

[0031] Therefore, this utility model proposes a horizontally polarized antenna 100, which aims to improve the omnidirectional radiation performance and bandwidth characteristics of the horizontally polarized antenna 100 under conditions of miniaturization, low profile and simple feeding.

[0032] Please see Figures 1 to 11 In one embodiment of this utility model, the horizontally polarized antenna 100 includes: substrate1; At least two dipole radiating units 2 are disposed on the substrate 1; At least two transmission lines 3 are disposed on the substrate 1, and at least two dipole radiating units 2 are connected through at least two transmission lines 3; Parasitic patch 4 is disposed on substrate 1. Both ends of parasitic patch 4 are coupled to at least two dipole radiating units 2 respectively, for forming a ring current distribution in the target frequency band to achieve horizontal polarization radiation.

[0033] In this embodiment, as Figure 1As shown, substrate 1 serves as the supporting carrier for the entire horizontally polarized antenna 100, and has a first side surface 101 for integrating and carrying the dipole radiating element 2, transmission line 3, and parasitic patch 4. Substrate 1 can be manufactured using printed circuit board technology, and materials such as FR-4, PTFE, CEM-1, or flexible printed circuit boards (FPC, LPC) are suitable. It not only possesses good mechanical strength and processing adaptability but also supports high-frequency signal transmission, making it suitable for the integration needs of various terminal devices. Its planar structure helps reduce the overall cross-sectional height, facilitating embedding within terminal devices and reducing space occupation.

[0034] like Figure 1 , Figure 8 or Figure 10 As shown, at least two dipole radiating elements 2 are disposed on the first side surface 101 of the substrate 1, serving as the main radiating component of the horizontally polarized antenna 100 and undertaking the function of radiating radio frequency energy. Each dipole radiating element 2 is an independent radiating structure, and its constituent dipole arms generally appear in pairs. The number of dipole arm pairs can be one, two, or even more, without specific limitation. The at least two dipole radiating elements 2 can be arranged in a linear, segmental, U-shaped, or other adapted layout on the substrate 1, and their size and shape can also be limited according to the target frequency band of 5150MHz to 5850MHz to achieve good resonance characteristics. Furthermore, the number of dipole radiating elements 2 can be two, three, or even more, without specific limitation.

[0035] like Figure 1 , Figure 8 or Figure 10 As shown, at least two transmission lines 3 are disposed on the first side surface 101 of the substrate 1 to connect at least two dipole radiating units 2, achieving series feeding. The at least two transmission lines 3 form a series feeding path using a coplanar multi-conductor transmission structure. For example, when two dipole radiating units 2 are provided, their transmission lines form a coplanar two-conductor transmission structure; when three dipole radiating units 2 are provided, the three sets of transmission lines are arranged in parallel to form a coplanar three-conductor transmission structure; for a larger number of dipole radiating units 2, their transmission lines also extend in parallel, forming a corresponding coplanar multi-conductor transmission structure. Figure 2 and Figure 3As shown, under excitation, because the currents on adjacent transmission lines 3 are in opposite directions, the resulting electromagnetic fields tend to cancel each other out in the far-field region, thus suppressing the leakage of radiated energy from the feed path itself. This characteristic allows transmission lines 3 to primarily perform signal conduction without interfering with the radiation pattern of the dipole radiating element 2 itself, ensuring the purity of the radiation characteristics of each dipole arm in the dipole radiating element 2. Simultaneously, by adjusting the physical length of transmission lines 3, the phase delay of the signal between each stage of the dipole radiating element 2 can be controlled, achieving an ideal current distribution in the target frequency band of 5150MHz to 5850MHz, thereby optimizing the overall radiation performance of the horizontally polarized antenna 100.

[0036] like Figure 1 , Figure 8 or Figure 10 As shown, the parasitic patch 4 is also disposed on the first side surface 101 of the substrate 1, and its two ends are respectively connected to at least two dipole radiating units 2 by electromagnetic coupling to form an edge-coupled feeding structure. The number of parasitic patches 4 can be flexibly configured according to design requirements, and can be set to one, two, three or more. For example, when only one parasitic patch 4 is disposed and there are two dipole radiating units 2, one end of the parasitic patch 4 can be coupled to one of the dipole radiating units 2, and the other end of the parasitic patch 4 can be coupled to the other dipole radiating unit 2; when two parasitic patches 4 are disposed and there are two dipole radiating units 2, one end of the two parasitic patches 4 can be coupled to one of the dipole radiating units 2, and the other end of the two parasitic patches 4 can be coupled to the other dipole radiating unit 2. It can be seen that when the number of parasitic patches 4 and dipole radiating units 2 is increased, their connection method is similar to the above connection method, and will not be repeated here.

[0037] like Figure 1 , Figure 8 or Figure 10 As shown, the parasitic patch 4 is not directly connected to the feed point, but instead obtains energy from the adjacent dipole radiating unit 2 through near-field electromagnetic induction. Under excitation, a continuously flowing ring current distribution is generated on the parasitic patch 4. This ring current distribution exhibits traveling wave characteristics and has a wide operating bandwidth, capable of covering the 5G communication frequency band from 5150MHz to 5850MHz. Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 for Figure 1 The ring-shaped current distribution formed by the structure; such as Figure 9 As shown, Figure 9 for Figure 8 The ring-shaped current distribution formed by the structure; such as Figure 11 As shown, Figure 11 for Figure 10 The ring-shaped current distribution formed by the structure. And regardless of... Figure 1 , Figure 8 or Figure 10 The resulting ring-shaped current distribution is the core of achieving horizontally polarized omnidirectional radiation. Its radiated electric field vector oscillates primarily along the horizontal direction, exhibiting a uniform and continuous radiation pattern within the horizontal plane, effectively enhancing the spatial coverage of the horizontal polarization component. Furthermore, by adjusting the width and length of the parasitic patch 4, its equivalent electrical length and impedance characteristics can be altered, achieving impedance matching over a wide bandwidth, reducing the voltage standing wave ratio (VSWR), and improving the radiation efficiency of the horizontally polarized antenna 100. The measured results are as follows... Figure 4 and Figure 5 The results show that it performs well in the 5150MHz to 5850MHz frequency band, with a voltage standing wave ratio of less than 2 and an average radiation efficiency of over 80%.

[0038] In summary, the technical solution of this utility model achieves structural integration through a substrate 1, utilizes at least two transmission lines 3 to connect at least two dipole radiating elements 2 to form a series-fed structure, ensures radiation purity through a low-radiation feeding path, and couples with at least two dipole radiating elements 2 via parasitic patches 4, exciting a ring current distribution in the target frequency band to achieve broadband, low-profile, omnidirectional horizontal polarized radiation. The overall size is compact, with the horizontally polarized antenna 100 measuring only 24.0mm × 24.0mm × 0.8mm. Its structure is simple, and the use of a single-layer substrate 1 simplifies feeding processing and reduces costs. Furthermore, the horizontally polarized antenna 100 of this utility model also possesses excellent bandwidth characteristics. Its three-dimensional radiation pattern is shown below. Figure 6 As shown in the figures, Figure (a) shows the three-dimensional radiation pattern of the horizontally polarized antenna 100 at 5200MHz, and Figure (b) shows the three-dimensional radiation pattern of the horizontally polarized antenna 100 at 5800MHz. It can be seen from the figures that at both 5200MHz and 5800MHz, the horizontally polarized antenna 100 exhibits stable omnidirectional radiation characteristics, and the electric field vector mainly oscillates along the horizontal direction, demonstrating good horizontal polarization radiation performance. This further verifies the ability of the horizontally polarized antenna 100 to achieve efficient omnidirectional coverage in the wide frequency band from 5150MHz to 5850MHz. The two-dimensional radiation pattern on the horizontal plane is shown in Figure (b). Figure 7 As shown in the figure, it can be observed that the horizontally polarized antenna 100 exhibits excellent omnidirectional performance in the horizontal plane, and the cross-polarization component is very small. Figure 7Figure (c) shows the horizontal radiation pattern of the horizontally polarized antenna 100 at 5200MHz, and Figure (d) shows the horizontal radiation pattern of the horizontally polarized antenna 100 at 5800MHz. Both patterns at these frequencies exhibit good omnidirectional radiation characteristics, indicating that the horizontally polarized antenna 100 can not only maintain stable horizontal polarization radiation over a wide frequency range but also effectively suppress unnecessary cross-polarization components, further improving communication quality and reliability. In other words, this technical solution, while maintaining a compact structure and simple power supply, can solve the problems of large size, narrow bandwidth, pattern distortion, and high integration difficulty inherent in traditional horizontally polarized antennas, thus improving the radiation performance of the horizontally polarized antenna 100.

[0039] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of this utility model, at least two transmission lines 3 are spaced apart and arranged opposite each other along a first direction.

[0040] In this embodiment, at least two transmission lines 3 are disposed on the substrate 1 to connect at least two dipole radiating elements 2 for series feeding. These at least two transmission lines 3 are arranged sequentially along a first direction, maintaining a spatially spaced and relative layout, i.e., adjacent transmission lines 3 extend parallel to each other, forming a coplanar multi-conductor transmission structure. This spaced and relative arrangement ensures stable electromagnetic coupling characteristics between adjacent transmission lines 3, while avoiding signal short circuits or impedance mismatches caused by direct electrical connections. When the radio frequency signal is transmitted step-by-step to each dipole radiating element 2 through the transmission lines 3, due to the continuity of the series feed path, the current flowing through adjacent transmission lines 3 flows in opposite directions, and the resulting electromagnetic fields tend to cancel each other out in the far field, thereby suppressing the leakage of radiated energy from the transmission lines 3 themselves. This characteristic allows the transmission lines 3 to primarily perform signal conduction functions without interfering with the main radiation modes of the dipole radiating elements 2 and the parasitic patch 4, ensuring the purity and stability of the overall radiation pattern of the horizontally polarized antenna 100. Meanwhile, by adjusting the length, spacing, and width of the transmission line 3 along the first direction, the phase delay and impedance matching characteristics of the signal can be controlled, the current distribution between each dipole radiating element 2 can be optimized, and the radiation efficiency and bandwidth performance of the horizontally polarized antenna 100 in the target frequency band of 5150MHz to 5850MHz can be improved.

[0041] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of the present invention, at least two dipole radiating units 2 are spaced apart and arranged opposite each other along a second direction.

[0042] In this embodiment, at least two dipole radiating elements 2 are disposed on the substrate 1 and arranged sequentially along the second direction, maintaining a certain spatial interval between them and in a relative arrangement. This second direction can be the same as, perpendicular to, or at other angles to the first direction, and is generally determined according to the overall antenna layout requirements. Figure 1 As shown, the second direction in this embodiment is perpendicular to the first direction. The spacing between at least two dipole radiating units 2 in the second direction is beneficial for controlling the electromagnetic coupling strength between units, avoiding mutual coupling effects and impedance mismatch caused by excessive distance, and providing a distributed excitation source for the parasitic patch 4.

[0043] "Relative arrangement" means that adjacent dipole radiating elements 2 correspond to each other in spatial position, forming a symmetrical or approximately symmetrical arrangement, which helps to achieve a balanced current distribution and a stable radiation field. When at least two dipole radiating elements 2 are connected in series through at least two transmission lines 3, the radio frequency signal can be transmitted sequentially to each level of dipole radiating element 2, forming a controllable phase relationship on each dipole radiating element 2. This series-feed structure, combined with a reasonable layout along the second direction, can optimize the overall current amplitude and phase distribution and improve the directivity and bandwidth performance of the horizontally polarized antenna 100.

[0044] Furthermore, this spaced and opposite arrangement facilitates coupling with the parasitic patch 4. Since both ends of the parasitic patch 4 are coupled to at least two dipole radiating elements 2, when the at least two dipole radiating elements 2 are symmetrically distributed in the second direction, they can provide excitation signals with similar amplitudes but opposite phases to the parasitic patch 4, thereby exciting a continuous ring current distribution on it. This ring current distribution exhibits traveling wave characteristics, which is crucial for achieving horizontally polarized omnidirectional radiation, and is particularly suitable for 5G communication applications in the 5150MHz to 5850MHz frequency band.

[0045] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of this utility model, at least two dipole radiating units 2 include a first dipole radiating unit 21 and a second dipole radiating unit 22. The first dipole radiating unit 21 includes a first oscillator arm 211 and a second oscillator arm 212, and the second dipole radiating unit 22 includes a third oscillator arm 221 and a fourth oscillator arm 222. At least two transmission lines 3 include a first transmission line 31 and a second transmission line 32. The first transmission line 31 connects the first oscillator arm 211 and the third oscillator arm 221, and the second transmission line 32 connects the second oscillator arm 212 and the fourth oscillator arm 222. The parasitic patch 4 includes a first parasitic patch 41 and a second parasitic patch 42. The first parasitic patch 41 connects the first oscillator arm 211 and the third oscillator arm 221, and the second parasitic patch 42 connects the third oscillator arm 221 and the fourth oscillator arm 222.

[0046] In this embodiment, the first dipole radiation unit 21 is composed of a first oscillator arm 211 and a second oscillator arm 212. As an independent dipole radiation structure, the first oscillator arm 211 and the second oscillator arm 212 can be disposed opposite to each other on the substrate 1, or even symmetrically disposed on the substrate 1 to form a dipole radiation unit 212. The second dipole radiation unit 22 is composed of a third oscillator arm 221 and a fourth oscillator arm 222. It is also an independent dipole radiation structure and is arranged at intervals from the first dipole radiation unit 21 along the second direction.

[0047] At least two transmission lines 3 are used to implement the series feed connection: the first transmission line 31 connects one end of the first dipole arm 211 to one end of the third dipole arm 221, and the second transmission line 32 connects one end of the second dipole arm 212 to one end of the fourth dipole arm 222, thereby electrically connecting the first dipole radiating unit 21 and the second dipole radiating unit 22 in series, forming a dual-path parallel series feed structure. After the radio frequency signal is input from the feed point, it passes sequentially through the first dipole arm 211 and the first transmission line 31 to the third dipole arm 221, and simultaneously through the second dipole arm 212 and the second transmission line 32 to the fourth dipole arm 222, realizing the cascade excitation of the first dipole radiating unit 21 and the second dipole radiating unit 22.

[0048] The parasitic patch 4 includes a first parasitic patch 41 and a second parasitic patch 42, both disposed on the substrate 1 and not directly connected to the power supply network. The first parasitic patch 41 is connected between the first oscillator arm 211 and the third oscillator arm 221, forming a non-direct electrical connection with them through edge coupling; the second parasitic patch 42 is connected between the second oscillator arm 212 and the fourth oscillator arm 222, also obtaining energy through electromagnetic coupling. When the first dipole radiation unit 21 and the second dipole radiation unit 22 are excited, the current on their oscillator arms generates a near-field electromagnetic field, which excites the induced current on the first parasitic patch 41 and the second parasitic patch 42 through coupling. Since the first parasitic patch 41 connects the first oscillator arm 211 and the third oscillator arm 221, and the second parasitic patch 42 connects the second oscillator arm 212 and the fourth oscillator arm 222, and each oscillator arm has a specific phase relationship in the series-fed structure, a ring-shaped current distribution is formed on the first parasitic patch 41 and the second parasitic patch 42, respectively. This ring-shaped current distribution exhibits traveling wave characteristics, supports wideband operation, and can achieve efficient horizontal polarization radiation in the 5150MHz to 5850MHz frequency band. The electric field vector oscillates mainly along the horizontal direction, forming an omnidirectional radiation pattern in the horizontal plane, improving spatial coverage. At the same time, by adjusting the length or width of the first parasitic patch 41 and the second parasitic patch 42, the coupling strength and impedance matching state between them and the corresponding oscillator arms can be optimized, further widening the operating bandwidth and reducing the voltage standing wave ratio.

[0049] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of the present invention, the first parasitic patch 41 and the second parasitic patch 42 are spaced apart and disposed opposite to each other along the first direction; And / or, the first oscillator arm 211 and the second oscillator arm 212 are spaced apart and arranged opposite each other along the first direction; And / or, the third vibrating arm 221 and the fourth vibrating arm 222 are spaced apart and arranged opposite each other along the first direction; And / or, the first oscillator arm 211 and the third oscillator arm 221 are spaced apart and arranged opposite each other along the second direction; And / or, the second vibrating arm 212 and the fourth vibrating arm 222 are spaced apart and arranged opposite each other along the second direction.

[0050] In this embodiment, the first parasitic patch 41 and the second parasitic patch 42 are spaced apart and arranged opposite each other along the first direction, indicating that they are located at different positions in this direction, and their geometric centers, extension directions, or coupling edges have a spatial correspondence, which can form a consistent radiation response or facilitate unified control of coupling strength. This relative relationship can be symmetrical to improve the uniformity of the radiation pattern; it can also be asymmetrical to adjust the excitation amplitude or phase and achieve beam optimization in the first direction.

[0051] Similarly, the first oscillator arm 211 and the second oscillator arm 212 are spaced apart and opposite to each other along the first direction, indicating that they constitute the two arms of the first dipole radiation unit 21, spatially positioned on both sides of the feed point or transmission path to form a basic radiation structure. Their relative relationship can be symmetrical to ensure balanced excitation, or asymmetrical to fine-tune the impedance or resonant frequency. The third oscillator arm 221 and the fourth oscillator arm 222 are arranged in the same way.

[0052] The first and third dipole arms 211 and 221 are spaced apart and arranged opposite each other along the second direction, indicating that the dipole arms from different dipole radiating units 2 on the same side are arranged correspondingly in the second direction, facilitating connection via the first transmission line 31 to achieve series feeding. This relative arrangement ensures a straight transmission path with controllable length, which is beneficial for signal transmission; its layout can be designed as symmetrical or asymmetrical according to actual wiring requirements to adapt to compact space or matching phase requirements. The relative arrangement of the second and fourth dipole arms 212 and 222 follows the same principle.

[0053] The aforementioned various "spaced and relative" spatial relationships can be used individually or in combination. When multiple layouts coexist, the entire antenna structure exhibits a regular spatial correspondence in both the first and second directions, improving the uniformity of excitation, the stability of impedance matching, and the consistency of the radiation pattern. Especially in the target frequency band of 5150MHz to 5850MHz, by rationally configuring the relative positions of each dipole radiating element 2, stable and uniformly distributed ring currents can be excited on the first parasitic patch 41 and the second parasitic patch 42, thereby achieving broadband, efficient, and omnidirectional horizontal polarized radiation.

[0054] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of the present invention, the substrate 1 has a first axis 102 and a second axis 103, the first axis 102 and the second axis 103 are intersecting, and the first parasitic patch 41 and the second parasitic patch 42 are symmetrically arranged about the first axis 102. And / or, the first oscillator arm 211 and the second oscillator arm 212 are symmetrically arranged about the first axis 102; And / or, the third vibrating arm 221 and the fourth vibrating arm 222 are symmetrically arranged about the first axis 102; And / or, the first oscillator arm 211 and the third oscillator arm 221 are symmetrically arranged about the second axis 103; And / or, the second oscillator arm 212 and the fourth oscillator arm 222 are symmetrically arranged about the second axis 103.

[0055] In this embodiment, a first axis 102 and a second axis 103 are defined on the substrate 1. The two axes intersect in the plane of the substrate 1, forming a spatially symmetrical reference. When the first parasitic patch 41 and the second parasitic patch 42 are symmetrically arranged about the first axis 102, it means that they are mirror-symmetrically distributed on both sides of the first axis 102, and their geometry, size, extension direction, and relative position with the excitation source are completely corresponding. This symmetry ensures that the excitation amplitude and phase obtained by the first parasitic patch 41 and the second parasitic patch 42 when receiving coupled energy from the dipole radiation unit 2 tend to be consistent. This is beneficial for exciting symmetrical ring current distributions on their respective structures, thereby enhancing the radiation symmetry along the first axis 102 in the horizontal plane, reducing pattern distortion, and improving the uniformity of omnidirectional coverage.

[0056] Similarly, when the first oscillator arm 211 and the second oscillator arm 212 are symmetrically arranged about the first axis 102, the two arms constituting the first dipole radiation unit 21 are symmetrically arranged on both sides of the first axis 102. This arrangement helps to achieve a symmetrical current distribution under differential excitation, improve polarization purity, and suppress common-mode radiation. Likewise, the symmetrical arrangement of the third oscillator arm 221 and the fourth oscillator arm 222 about the first axis 102 can ensure the structural symmetry of the second dipole radiation unit 22 and improve the stability of its radiation characteristics.

[0057] When the first dipole arm 211 and the third dipole arm 221 are symmetrically arranged about the second axis 103, it means that the dipole arms on the same side from different dipole radiating units 2 are mirror-symmetrical on both sides of the second axis 103. This symmetry ensures that the path of the first transmission line 31 connecting the first dipole arm 211 and the third dipole arm 221 is symmetrical, which is beneficial for consistent phase delay of the control signal and achieving balanced excitation of the series feed path. Similarly, the symmetrical arrangement of the second dipole arm 212 and the fourth dipole arm 222 about the second axis 103 ensures that the connection path of the second transmission line 32 is also symmetrical, ensuring consistent electrical characteristics between the dipole arms on the right side and further improving the symmetry and stability of the entire series feed system.

[0058] The aforementioned symmetry relationships can be used individually or in combination. When multiple symmetry relationships exist simultaneously, the entire horizontally polarized antenna 100 forms a double-symmetric or approximately double-symmetric layout in the plane formed by the first axis 102 and the second axis 103, enhancing the excitation balance, impedance matching consistency, and overall symmetry of the radiation pattern among the dipole radiating elements 2. Especially in the target frequency band of 5150MHz to 5850MHz, this symmetric structure is more conducive to exciting a uniform and stable ring current distribution on the first parasitic patch 41 and the second parasitic patch 42, achieving broadband, efficient, and omnidirectional horizontally polarized radiation.

[0059] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of the present invention, the first parasitic patch 41 includes a first patch segment 411, a second patch segment 412, and a third patch segment 413. The second patch segment 412 couples the first patch segment 411 and the third patch segment 413 together. The first patch segment 411 is coupled to the first oscillator arm 211, and the third patch segment 413 is coupled to the third oscillator arm 221. The first patch segment 411 and the third patch segment 413 are symmetrically arranged about the second axis 103. The second parasitic patch 42 includes a fourth patch segment 421, a fifth patch segment 422, and a sixth patch segment 423. The fifth patch segment 422 couples the fourth patch segment 421 and the sixth patch segment 423 together. The fourth patch segment 421 is coupled to the second oscillator arm 212, and the sixth patch segment 423 is coupled to the fourth oscillator arm 222. The fourth patch segment 421 and the sixth patch segment 423 are symmetrically arranged about the second axis 103, and the fifth patch segment 422 and the second patch segment 422 are symmetrically arranged about the first axis 102.

[0060] In this embodiment, the first parasitic patch 41 is composed of a first patch segment 411, a second patch segment 412, and a third patch segment 413, all of which are disposed on the substrate 1. They are not directly electrically connected to each other, but are coupled through a spatial electromagnetic field. Specifically, the first patch segment 411 is connected to the first oscillator arm 211 via edge coupling and is used to receive excitation energy from the first dipole radiation unit 21; the third patch segment 413 is coupled to the third oscillator arm 221 and receives excitation energy from the second dipole radiation unit 22; the second patch segment 412 is located between the first patch segment 411 and the third patch segment 413 and is connected to them via near-field coupling to form a continuous energy transfer path. Since the first oscillator arm 211 and the third oscillator arm 221 are symmetrically arranged about the second axis 103, and the first patch segment 411 and the third patch segment 413 are also symmetrically arranged about the second axis 103, the two are completely corresponding in geometric position, size and coupling relationship with the excitation source. Therefore, they can obtain excitation signals with equal amplitude and symmetrical phase during operation, which is conducive to forming a balanced current distribution on the first parasitic patch 41.

[0061] Similarly, the second parasitic patch 42 is composed of a fourth segment 421, a fifth segment 422, and a sixth segment 423. The fourth segment 421 is coupled to the second oscillator arm 212, the sixth segment 423 is coupled to the fourth oscillator arm 222, and the fifth segment 422 is located between the two, achieving energy transfer through electromagnetic coupling. The fourth segment 421 and the sixth segment 423 are symmetrically arranged about the second axis 103 to ensure that the excitation they obtain from the second oscillator arm 212 and the fourth oscillator arm 222 has good symmetry, thereby exciting a uniform current response on the second parasitic patch 42.

[0062] Furthermore, the second parasitic patch 412 and the fifth parasitic patch 422 are symmetrically arranged about the first axis 102, that is, the middle sections of the first parasitic patch 41 and the second parasitic patch 42 are mirror-symmetrical on both sides of the first axis 102. This symmetry ensures that the first parasitic patch 41 and the second parasitic patch 42 maintain a high degree of consistency in structural layout and electromagnetic behavior, which can enhance the cooperative working capability between the first parasitic patch 41 and the second parasitic patch 42. When the radio frequency signal excites each oscillator arm sequentially through the series feed path, the first parasitic patch 411 and the third parasitic patch 413, and the fourth parasitic patch 421 and the sixth parasitic patch 423 respectively obtain excitation from symmetrical positions, and the excitation signals are nearly out of phase, thereby exciting a ring-like current distribution flowing in the direction of first parasitic patch 411→second parasitic patch 412→third parasitic patch 413 in the first parasitic patch 41, and exciting a ring-like current distribution flowing in the direction of fourth parasitic patch 421→fifth parasitic patch 422→sixth parasitic patch 423 in the second parasitic patch 42. This ring current distribution has traveling wave characteristics, supports wideband operation, and can achieve efficient horizontally polarized omnidirectional radiation in the 5150MHz to 5850MHz frequency band.

[0063] By designing the parasitic patch into four segments and introducing multiple symmetries—including the symmetry between the first segment 411 and the third segment 413, the fourth segment 421 and the sixth segment 423 about the second axis 103, and the symmetry between the second segment 412 and the fifth segment 422 about the first axis 102—not only can the regularity and excitation balance of the horizontally polarized antenna 100 be improved, but the symmetry and stability of the radiation pattern can also be enhanced. Simultaneously, the segmented structure facilitates adjustment of the size and spacing of each segment, enabling impedance matching optimization and bandwidth expansion.

[0064] Understandably, please refer to Figure 1 , Figure 8 or Figure 10 The widths of the first segment 411, the second segment 412, and the third segment 413 can be flexibly adjusted according to actual electromagnetic performance requirements to optimize impedance matching, excitation intensity, and current distribution characteristics. At least one of the first segment 411 and the third segment 413 has a width less than or equal to the width of the second segment 412, such as... Figure 1 As shown, the widths of the first fragment 411 and the third fragment 413 are both smaller than the width of the second fragment 412, while... Figure 8As shown, the widths of the first fragment 411 and the second fragment 412 are both equal to the width of the third fragment 413, meaning they have the same width. Alternatively, the width of the first fragment 411 is less than the width of the second fragment, and the width of the second fragment is less than the width of the third fragment 413. Or, the width of the first fragment 411 is greater than the width of the second fragment, and the width of the second fragment is greater than the width of the third fragment 413.

[0065] Similarly, the lengths of the first segment 411, the second segment 412, and the third segment 413 can also be adjusted according to actual electromagnetic performance requirements to optimize impedance matching, excitation intensity, and current distribution characteristics. At least one of the first segment 411 and the third segment 413 must have a length less than, greater than, or equal to the length of the second segment, such as... Figure 1 and Figure 8 As shown, the first fragment 411 and the third fragment 413 have the same length, and the third fragment 413 has a longer length than the second fragment 412. Figure 10 As shown, the length of the first fragment 411 is less than the length of the second fragment 412, and the length of the second fragment 412 is less than the length of the third fragment 413; conversely, the length of the first fragment 411 can also be greater than the length of the second fragment 412, and the length of the second fragment 412 can be greater than the length of the third fragment 413. Alternatively, the lengths of the first fragment 411, the second fragment 412, and the third fragment 413 can be the same. No specific limitations are imposed here.

[0066] Similarly, please see Figures 1 to 11 The widths of the fourth segment 421, the fifth segment 422, and the sixth segment 423 can be flexibly adjusted according to actual electromagnetic performance requirements to optimize impedance matching, excitation intensity, and current distribution characteristics. At least one of the fourth segment 421 and the sixth segment 423 has a width less than or equal to the width of the fifth segment 422, such as... Figure 1 As shown, the widths of the fourth segment 421 and the sixth segment 423 are both smaller than the width of the fifth segment 422, while... Figure 8 As shown, the widths of the fourth fragment 421 and the fifth fragment 422 are both equal to the width of the sixth fragment 423, meaning they have the same width. Alternatively, the width of the fourth fragment 421 is less than the width of the fifth fragment 422, and the width of the fifth fragment 422 is less than the width of the sixth fragment 423. Or, the width of the fourth fragment 421 is greater than the width of the fifth fragment 422, and the width of the fifth fragment 422 is greater than the width of the sixth fragment 423.

[0067] Similarly, the lengths of the fourth segment 421, the fifth segment 422, and the sixth segment 423 can also be flexibly adjusted according to actual electromagnetic performance requirements to optimize impedance matching, excitation intensity, and current distribution characteristics. At least one of the fourth segment 421 and the sixth segment 423 must have a length less than, greater than, or equal to the length of the fifth segment 422. Figure 1 and Figure 8 As shown, the fourth segment 421 and the sixth segment 423 have the same length, and the sixth segment 423 has a longer length than the fifth segment 422. Figure 10 As shown, the length of the fourth fragment 421 is less than the length of the fifth fragment 422, and the length of the fifth fragment 422 is less than the length of the sixth fragment 423; conversely, the length of the fourth fragment 421 could be greater than the length of the fifth fragment 422, and the length of the fifth fragment 422 could be greater than the length of the sixth fragment 423. Alternatively, the lengths of the fourth fragment 421, the fifth fragment 422, and the sixth fragment 423 could be the same. No specific limitations are set here.

[0068] Please see Figure 1 , Figure 8 or Figure 10 In one embodiment of this utility model, the cross-sectional shape of the first parasitic patch and / or the second parasitic patch is U-shaped.

[0069] In this embodiment, the first parasitic patch 41 is composed of a first patch segment 411, a second patch segment 412, and a third patch segment 413. The first patch segment 411 and the third patch segment 413 are respectively disposed at both ends of the second patch segment 412. The three segments form a continuous energy transfer path through spatial electromagnetic coupling, and the whole presents a U-shaped structure on the substrate. The opening direction of the first parasitic patch 41 corresponds to the first direction. The first patch segment 411 and the third patch segment 413 are coupled to the first oscillator arm 211 and the third oscillator arm 221, respectively, for obtaining excitation energy from the dipole radiation unit. The second patch segment 412 serves as the main current convergence region, receiving the coupled energy from both ends and forming a ring-like current distribution flowing along the U-shaped path.

[0070] Similarly, the second parasitic patch 42 is composed of a fourth patch segment 421, a fifth patch segment 422 and a sixth patch segment 423. The fourth patch segment 421 and the sixth patch segment 423 are located at the two ends of the fifth patch segment 422, and the whole is also in the form of a U-shaped structure. Its two ends are coupled to the second oscillator arm 212 and the fourth oscillator arm 222, respectively. The middle section of the fifth patch segment 422 is used to form a continuous current path.

[0071] By setting the shapes of the first parasitic patch 41 and the second parasitic patch 42 to U-shape, the first parasitic patch 41 and the second parasitic patch 42 can have good symmetry and directional consistency in spatial layout. When the first patch segment 411 and the third patch segment 413 are symmetrically arranged about the second axis 103, and the fourth patch segment 421 and the sixth patch segment 423 are also symmetrically arranged about the second axis 103, the U-shaped structure further enhances the balance of excitation, which is beneficial for exciting a stable and uniform traveling wave current mode in the target frequency band of 5150MHz to 5850MHz. The current propagates along the U-shaped path, forming an electric field oscillation dominated by the horizontal direction, realizing horizontal polarized radiation, and having good omnidirectionality in the horizontal plane.

[0072] Furthermore, the U-shaped structure has a compact layout and occupies a small area, making it easy to achieve a high degree of integration within the limited space of the substrate 1. Its open ends facilitate alignment and coupling with different vibrator arms, enhancing electromagnetic coupling efficiency. At the same time, by adjusting the length, width, and gap of each segment of the U-shape, the resonant frequency, bandwidth, and impedance matching characteristics can be flexibly controlled to meet the broadband performance requirements of 5G communication.
