[0028] Common element symbols are used throughout the figures and the embodiments to indicate the same or similar components. The arrangement of the present disclosure will be readily understood from the following detailed description taken in conjunction with the accompanying figures.
[0029] The following disclosure provides many different arrangements or examples for implementing the different features of the provided subject matter. Specific examples of components and arrangements are described below to explain certain aspects of the present disclosure. Of course, these components and arrangements are only examples and are not intended to be limiting. For example, in the following description, the formation of a first feature above or on a second feature may include an arrangement where the first feature and the second feature are formed or disposed in direct contact, and may also include an arrangement where additional features may be formed or disposed between the first feature and the second feature such that the first feature and the second feature are not in direct contact. Additionally, the present disclosure may repeat element symbols and / or letters in various examples. This repetition is for simplicity and clarity purposes and does not itself prescribe the relationship between the various arrangements and / or configurations discussed.
[0030] Figure 1A A perspective view of an electronic device 1a arranged according to the present disclosure. In some arrangements, the electronic device 1a may be or include, for example, an antenna device or an antenna package. In some arrangements, the electronic device 1a may be or include, for example, a wireless device, such as a user equipment (UE), a mobile station, a mobile device, a device communicating with the Internet of Things (IoT), etc. In some arrangements, the electronic device 1a may be or include a portable device.
[0031] The electronic device 1a may include a ground plane 10g, field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6, feed elements 10f1 and 10f2, and vias 10v1, 10v2, and 10v3.
[0032] The field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can also be referred to as conductive elements, antenna elements, or radiation elements. The field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can be configured to radiate and / or receive electromagnetic (EM) waves / signals, such as radio waves, microwaves, infrared waves, X-rays, gamma rays, etc. The field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can be configured to operate at any desired frequency (frequency band and / or bandwidth) to support fifth-generation (5G) communication, ultra-5G communication, and / or 6G communication. For example, the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can be configured to operate in a microwave frequency band, a sub-6 GHz frequency band, a 5 GHz frequency band, a terahertz (THz) frequency band, etc.
[0033] The field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can each be electrically coupled to a ground plane 10g via vias 10v1. The vias 10v1 can intersect the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 perpendicularly. As used herein, the term "coupled" is used to describe two circuits that are close enough to permit mutual influence, inductive coupling, energy coupling, etc.
[0034] Although eight vias 10v1 are connected to each of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6, the number of vias 10v1 is not limited thereto. In some arrangements, any number of vias 10v1 can be present, depending on the design requirements.
[0035] By electrically coupling the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 to the ground plane 10g (which can be referred to as a grounding element), interference between the feeding elements 10f1 and 10f2 can be reduced, which can help improve the antenna performance of the electronic device 1a. Additionally, the ground plane 10g can reflect the EM waves emitted by the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6, which helps improve the radiation efficiency and directivity of the electronic device 1a. In some arrangements, the ground plane 10g can help improve impedance matching by providing a ground potential or a reference point for radiation and reducing mismatch losses.
[0036] The field patterns 10p1, 10p2, 10p4, and 10p5, as well as the feeding elements 10f1, can be part of the antenna 14. The field patterns 10p1, 10p2, 10p4, and 10p5, as well as the feeding elements 10f1, can be jointly configured to form or constitute the antenna 14. The antenna 14 can include a magneto-electric (ME) dipole antenna.
[0037] For example, the field patterns 10p1, 10p2, 10p4, and 10p5 can be the electric dipoles of the antenna 14. The via hole 10v1 connecting the field patterns 10p1, 10p2, 10p4, and 10p5 can be the magnetic dipole of the antenna 14. The electric dipole and the magnetic dipole of the ME dipole antenna work together to radiate EM waves and facilitate communication. This configuration makes the ME dipole antenna suitable for a wide range of applications, including wireless communication, radar, and sensing systems.
[0038] The field patterns 10p1, 10p2, 10p4, and 10p5 can include or be arranged in a 2×2 array. The feeding element 10f1 can be disposed at the center of the field patterns 10p1, 10p2, 10p4, and 10p5. The field patterns 10p1, 10p2, 10p4, and 10p5 can be symmetrically arranged around the feeding element 10f1. The field patterns 10p1, 10p2, 10p4, and 10p5 can be evenly spaced from the feeding element 10f1. The feeding element 10f1 can be disposed between the field patterns 10p1 and 10p2 and between the field patterns 10p4 and 10p5.
[0039] The feeding element 10f1 can be electrically coupled to an electronic component (such as Figure 1C the electronic component 12) via the via hole 10v2. The via hole 10v2 can intersect the feeding element 10f1 perpendicularly, and the midpoint of the intersection is the feeding point. The via hole 10v2 can be disposed in the opening 10gh of the ground plane 10g. The via hole 10v2 can be spaced from the ground plane 10g. The field patterns 10p1, 10p2, 10p4, and 10p5 may be capable of being excited by the feeding element 10f1.
[0040] The field patterns 10p2, 10p3, 10p5, and 10p6 and the feeding element 10f2 can be part of the antenna 15. The field patterns 10p2, 10p3, 10p5, and 10p6 and the feeding element 10f2 can be jointly configured to form or constitute the antenna 15. The antenna 15 can include an ME dipole antenna.
[0041] For example, the field patterns 10p2, 10p3, 10p5, and 10p6 can be the electric dipoles of the antenna 15. The via hole 10v1 connecting the field patterns 10p2, 10p3, 10p5, and 10p6 can be the magnetic dipole of the antenna 15.
[0042] The field patterns 10p2, 10p3, 10p5, and 10p6 can include or be arranged in a 2×2 array. The feeding element 10f2 can be disposed at the center of the field patterns 10p2, 10p3, 10p5, and 10p6. The field patterns 10p2, 10p3, 10p5, and 10p6 can be symmetrically arranged around the feeding element 10f2. 10p2, 10p3, 10p5, and 10p6 can be evenly spaced from the feeding element 10f2. The feeding element 10f2 can be disposed between the field patterns 10p2 and 10p3 and between the field patterns 10p5 and 10p6.
[0043] The feeding element 10f2 can be electrically coupled to an electronic component (such as Figure 1C the electronic component 12 in). The via 10v3 can intersect the feeding element 10f2 perpendicularly, and the midpoint of the intersection is the feeding point. The via 10v3 can be disposed in the opening 10gh of the ground plane 10g. The via 10v3 can be spaced apart from the ground plane 10g. The field patterns 10p2, 10p3, 10p5, and 10p6 may be capable of being excited by the feeding element 10f2.
[0044] The antenna 14 and the antenna 15 can include a common field pattern. The antenna 14 and the antenna 15 can share a common field pattern. For example, the field pattern 10p2 and the field pattern 10p5 can be the common field patterns of the antenna 14 and the antenna 15. For example, the field pattern 10p2 and the field pattern 10p5 can be shared by the antenna 14 and the antenna 15. For example, the field pattern 10p2 and the field pattern 10p5 can both be part of the antenna 14 and the antenna 15. For example, both the field pattern 10p2 and the field pattern 10p5 may be capable of being excited by the feeding element 10f1. For example, both the field pattern 10p2 and the field pattern 10p5 may be capable of being excited by the feeding element 10f2.
[0045] The antenna 14 and the antenna 15 can have the same or similar structures. In some arrangements, the distance or spacing between the feeding elements 10f1 and 10f2 can be a fraction of the wavelength of the operating frequency, such as from 0.2λ to 0.3λ. In some arrangements, the distance or spacing between the feeding elements 10f1 and 10f2 can be less than half of the wavelength of the operating frequency. As stated, by electrically coupling the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 to the ground plane 10g, the interference between the feeding elements 10f1 and 10f2 can be reduced.
[0046] In some arrangements, the ground plane 10g, the multiple field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6, the feeding elements 10f1 and 10f2, and the vias 10v1, 10v2, and 10v3 can each include a conductive material, such as a metal or a metal alloy. Examples of the conductive material can include but are not limited to gold (Au), silver (Ag), copper (Cu), platinum (Pt), palladium (Pd), other metals or alloys, or combinations thereof.
[0047] In some arrangements, antenna 14 and antenna 15 can form a beamforming antenna structure. Antenna 14 and antenna 15 can generate focused and directional EM beams. For example, antenna 14 and antenna 15 can generate constructive interference in a desired direction by adjusting their phases and amplitudes. In some arrangements, antenna 14 and antenna 15 can generate constructive interference in the far field region. In some arrangements, antenna 14 and antenna 15 can have far-field interference. In the case of far-field interference, the EM waves have traveled a significant distance from their source, and their wavefronts become nearly flat. Therefore, the interference field pattern formed in the far field region can be relatively stable and predictable.
[0048] Figure 1B Top view of the electronic device 1a according to an arrangement of the present disclosure.
[0049] Some or all of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can have the same or similar shapes. Some or all of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can be geometrically similar. Some or all of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 can be circular, rectangular, oval, semi-circular, pentagonal, hexagonal, heptagonal, octagonal, etc. The feeding element 10f1 can have a first portion adjacent to one side (or lateral side) of the field pattern 10p1, and a second portion connected to and extending from the first portion beyond the lateral side of the field pattern 10p1. The second portion can also extend beyond the lateral side of the field pattern 10p4. For example, the feeding element 10f1 can extend between the field patterns 10p1 and 10p4.
[0050] The vias 10v1 can be arranged along the lateral sides, outer surfaces, edges, or boundaries of each of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6. The vias 10v1 can be arranged along three sides of each of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6. However, in some arrangements, the vias 10v1 can be arranged along one side, two sides, or four sides of each of the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6.
[0051] The via hole 10v2 is disposed adjacent to one side or one end of the feeding element 10f1. For example, the via hole 10v2 is adjacent to one of the side and one end of the feeding element 10f1. In some arrangements, the via hole 10v2 is disposed at the center of the feeding element 10f1. The via hole 10v3 is disposed adjacent to one side or one end of the feeding element 10f2. For example, the via hole 10v3 is adjacent to one of the side and one end of the feeding element 10f2. In some arrangements, the via hole 10v3 is disposed at the center of the feeding element 10f2. For example, the feeding element 10f1 may have a portion extending beyond the lateral side of the field pattern 10p1, and the via hole 10v2 may be connected to the portion. For example, the feeding element 10f1 may have a portion extending beyond the lateral side of the field pattern 10p4, and the via hole 10v2 may be connected to the portion.
[0052] Figure 1C is a cross-section of the electronic device 1a according to an arrangement of the present disclosure. In some arrangements, Figure 1C may be the cross-section of the line AA' passing through Figure 1B . Figure 1C ' is a cross-section of the electronic device 1a according to an arrangement of the present disclosure. In some arrangements, Figure 1C ' may be the cross-section of the line AA' passing through Figure 1B .
[0053] The electronic device 1a may further include a radiation structure 10, a circuit structure 11, an electronic component 12, and an encapsulation 13.
[0054] The radiation structure 10 may be capable of operating at multiple frequencies (frequency bands and / or bandwidths). For example, the radiation structure 10 may be configured to operate at relatively high frequencies (relatively high frequency bands and / or bandwidths) and relatively low frequencies (relatively low frequency bands and / or bandwidths). For example, the radiation structure 10 may be configured to radiate and / or receive EM waves having relatively high frequencies and EM waves having relatively low frequencies. In some arrangements, the radiation structure 10 may be capable of radiating and / or receiving EM waves having relatively high frequencies and EM waves having relatively low frequencies in parallel.
[0055] The radiation structure 10 may include a surface 101, a surface 102 opposite to the surface 101, and lateral surfaces (or side walls) 103, 104 extending between the surfaces 101 and 102. The surface 101 and / or the surface 102 of the radiation structure 10 may be parallel to the xy plane. The radiation structure 10 may include an antenna layer ( Figure 1A and Figure 1BThe field patterns 10p1, 10p2, 10p3, 10p4, 10p5 and 10p6, and the feeding elements 10f1 and 10f2 in [[ ]] are located in the antenna layer), the ground plane 10g, the dielectric layers 10d1, 10d2, and the vias 10v1, 10v2 and 10v3. In some arrangements, as Figure 1C shown in [[ ]], the dielectric layer 10d2 may comprise a multi-layer structure having a number of layers 10d21, 10d22 and 10d23.
[0056] The antenna layer may be adjacent to the surface 102 of the radiation structure 10. Although there is one antenna layer in Figure 1C , the number of antenna layers is not limited thereto. In some arrangements, depending on the design requirements, any number of antenna layers may be present.
[0057] The antenna layer may be partially or completely within (or covered by) the dielectric layer 10d1. In some arrangements, the upper surfaces (not labeled in the figure) of the field patterns 10p1, 10p2, 10p3 may be exposed by the dielectric layer 10d1 and exposed on the surface 102 of the radiation structure 10.
[0058] The ground plane 10g may be adjacent to the surface 101 of the radiation structure 10. The ground plane 10g may be disposed below the antenna layer ( Figure 1A and Figure 1B the field patterns 10p1, 10p2, 10p3, 10p4, 10p5 and 10p6, and the feeding elements 10f1 and 10f2 in [[ ]] are located in the antenna layer). Although there is one ground plane in Figure 1C , the number of ground planes is not limited thereto. In some arrangements, depending on the design requirements, any number of ground planes may be present. The ground plane 10g may be partially or completely within (or covered by) the dielectric layer 10d2.
[0059] The ground plane 10g and the antenna layer may at least partially overlap each other in a direction generally perpendicular to the surface 101 and / or surface 102 of the radiation structure 10. For example, the vertical projection of the field pattern 10p1 may be within the boundary of the ground plane 10g. For example, the vertical projection of the field pattern 10p2 may be within the boundary of the ground plane 10g. For example, the vertical projection of the field pattern 10p3 may be within the boundary of the ground plane 10g.
[0060] The vias 10v1, 10v2 and 10v3 may be electrically coupled between the antenna layer and the ground plane 10g. Although there are three vias stacked above the ground plane 10g in Figure 1C , the number of stacked vias is not limited thereto. In some arrangements, depending on the design requirements, any number of stacked vias may be present.
[0061] The feeding elements 10f1 and 10f2 can be at the same horizontal level as the field patterns 10p1, 10p2, and 10p3. For example, the feeding elements 10f1 and 10f2 can be at the same height as the field patterns 10p1, 10p2, and 10p3 relative to the surface 111 of the circuit structure 11. For example, the feeding elements 10f1 and 10f2 can be at the same height as the field patterns 10p1, 10p2, and 10p3 relative to the ground plane 10g. The feeding element 10f1 may not overlap perpendicularly with the field patterns 10p1 and 10p2. The feeding element 10f1 may not overlap with the field patterns 10p1 and 10p2 in a direction generally perpendicular to the surface 111 of the circuit structure 11. The feeding element 10f2 may not overlap perpendicularly with the field patterns 10p2 and 10p3. The feeding element 10f2 may not overlap with the field patterns 10p2 and 10p3 in a direction generally perpendicular to the surface 111 of the circuit structure 11.
[0062] The vias 10v1, 10v2, and 10v3 can be covered, encapsulated, or surrounded by the dielectric layer 10d2. In some arrangements, the dielectric layers 10d1 and 10d2 can include pre-impregnated composite fibers (e.g., prepregs), ceramic-filled polytetrafluoroethylene (PTFE) composites, borophosphosilicate glass (BPSG), silicon oxide, silicon nitride, silicon oxynitride, undoped silicate glass (USG), any combination thereof, or the like. Examples of prepregs can include, but are not limited to, multilayer structures formed by stacking or laminating multiple pre-impregnated materials / sheets. In some arrangements, the dielectric layers 10d1 and 10d2 can include the same material as the encapsulant 13.
[0063] The circuit structure 11 can be disposed adjacent to the surface 101 of the radiation structure 10. The circuit structure 11 can be disposed above or on the surface 101 of the radiation structure 10. The circuit structure 11 can be disposed below the radiation structure 10. The circuit structure 11 can contact (e.g., directly contact) the ground plane 10g of the radiation structure 10. The ground plane 10g can be disposed between the circuit structure 11 and the antenna layer (in which the field patterns 10p1, 10p2, 10p3, 10p4, 10p5, and 10p6 as well as the feeding elements 10f1 and 10f2 are located). The ground plane 10g can be configured to mitigate electromagnetic interference (EMI) on the circuit structure 11.
[0064] In some arrangements, the circuit structure 11 may be or include, for example, a substrate. In some arrangements, the circuit structure 11 may include, for example, a printed circuit board (PCB), such as a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated fiberglass-based copper foil laminate. In some arrangements, the circuit structure 11 may include a dielectric layer 11d, which may include the dielectric materials described above with respect to dielectric layers 10d1 and 10d2. In some arrangements, as Figure 1C shown in ', the dielectric layer 11d may include a multilayer structure having a number of layers 11d1, 11d2, and 11d3.
[0065] In some arrangements, the circuit structure 11 may include conductive pads, traces, vias, layers, other conductive elements, or other interconnects. For example, the circuit structure 11 may include one or more transmit lines or communication cables. For example, the circuit structure 11 may include one or more conductive pads 11p that are close to, adjacent to, or embedded in the surface 111 of the circuit structure 11 and are exposed by the surface.
[0066] For example, the circuit structure 11 may include one or more vias 11v. In some arrangements, the vias 11v may be disposed above or on the surface 111 and electrically couple the conductive pads 11p on the surface 111. The vias 11v may be covered by the dielectric material of the circuit structure 11. Some of the vias 11v may be electrically coupled to the feed elements 10f1 and 10f2. Some of the vias 11v may be electrically coupled to the ground plane 10g. In some arrangements, the vias 11v may provide a feed signal to the ME dipole antennas of the radiating structure 10 (such as Figure 1A the antennas 14 and 15 in ).

[0072] The feeding elements 10f1 and 10f2 can be located at different horizontal levels relative to the field patterns 10p1, 10p2, and 10p3. For example, the feeding elements 10f1 and 10f2 can be located at a height lower than the field patterns 10p1, 10p2, and 10p3 relative to the surface 111 of the circuit structure 11. For example, the feeding elements 10f1 and 10f2 can be located at a height lower than the field patterns 10p1, 10p2, and 10p3 relative to the ground plane 10g. For example, the feeding elements 10f1 and 10f2 can be vertically separated from the field patterns 10p1, 10p2, and 10p3.
[0073] By vertically separating the feeding elements 10f1 and 10f2 from the field patterns 10p1, 10p2, and 10p3, a more compact design is provided, which can help reduce the overall size of the electronic device 1d. Additionally, vertically separating the feeding elements 10f1 and 10f2 from the field patterns 10p1, 10p2, and 10p3 can also help reduce the mutual coupling between elements and improve the isolation between elements, which can result in preferred overall antenna performance. In some arrangements, the feeding elements 10f1 and 10f2 can be disposed at different heights relative to the surface 111 (or the ground plane 10g) of the circuit structure 11. For example, the feeding element 10f1 can be located at a height lower than the feeding element 10f2 relative to the surface 111 (or the ground plane 10g) of the circuit structure 11.

[0076] Figure 1F Shows the current distribution of the electronic device 1a for an arrangement according to the present disclosure.
[0077] The all-black vector t1 represents a magnetic field between 240A / m (amperes / meter) and 300A / m, the striped vector t2 represents a magnetic field between 120A / m and 210A / m, and the all-white vector t3 represents a magnetic field between 0A / m and 90A / m. In order to reduce interference between the feeding elements 10f1 and 10f2, the field patterns 10p1, 10p2, 10p3, 10p4, 10p5 and 10p6 are electrically coupled to the ground plane 10g. It is shown that the current on the feeding elements 10f1 and 10f2 generally flows up and down, so that the current intensity is larger upward and downward, and the lateral interference (left and right directions, i.e., between the feeding elements 10f1 and 10f2) is reduced. In some arrangements, the interference between the field patterns 10p1 and 10p3 can be reduced. In some arrangements, the interference between the field patterns 10p4 and 10p6 can be reduced. In some arrangements, interference between antennas 14 and 15 may be reduced. This results in a more efficient and more effective radiation pattern of the antenna (eg, ME dipole antenna) of the electronic device 1a, because the electric and magnetic fields work together to propagate electromagnetic waves.
[0078] According to some arrangements of the present disclosure, the utilization of a common antenna panel design allows an increase in antenna gain while maintaining a smaller antenna array size than a conventional ME dipole antenna array. This meets the demand for miniaturization. Figure 4B The simulation data in shows that the common antenna panel design (with a 1×4 array, such as Figure 2A ) achieves a 3.8 dB gain increase compared to a single ME dipole. Figure 4A The simulated antenna gain pattern shows that the common antenna panel design (with a 1×4 array, such as Figure 2A helps increase the antenna's directivity and coverage area.
[0079] Furthermore, connecting the common antenna board to the ground plane reduces interference between the feed lines. This results in improved signal quality and reliability without requiring an increase in package size.
[0080] In addition, the common board design provides the flexibility to adjust the impedance according to different frequency and bandwidth requirements. This enhances design flexibility without increasing the overall area.
