[0030] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application.

It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0031] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are described in some detail. Of course, they are merely examples and are not intended to limit the present application. In addition, reference numerals can be repeated in different examples in the present application. Such repetition is for the purpose of simplicity and clarity and does not indicate any relationship between the various embodiments and / or settings discussed.

[0032] To solve the technical problem that the omni-directionality and efficiency of the calibration antenna cannot meet the wideband working requirement in the prior art, the present application provides an antenna and an electronic device with the antenna. The antenna has a half-circular structure through two symmetrical radiators in the up and down directions, can keep the current of the up and down radiators in the same direction in the ultra-wideband range, and realizes the omni-directional radiation characteristics of the antenna. In addition, the second part extending based on the half-circular structure can keep the characteristic impedance of the antenna stable and smooth with the change of the frequency.

[0033] Figure 1 A structural schematic diagram of an antenna provided by the present embodiment is shown in Figure 1 The antenna includes a substrate 1 and first and second radiators 2 and 3 with the same shape.

[0034] The first and second radiators 2 and 3 each include a first part 4 (41, 42) and a second part 5 (51, 52); wherein the first part 4 (41, 42) is half-circular, and the first straight side of the second part 5 (51, 52) is butted against the diameter side of the first part 4 (41, 42).

[0035] The first and second radiators 2 and 3 are mirror-symmetrical, and the opening directions of the first parts 41 and 42 of the first and second radiators 2 and 3 are opposite; the first radiator 2 is arranged on the upper half area of the front surface of the substrate 1, and the second radiator 3 is arranged on the lower half area of the back surface of the substrate 1.

[0036] In the embodiment, the first radiator 2 and the second radiator 3 have the same shape, which can include that the first part 41 of the first radiator 2 has the same shape as the first part 42 of the second radiator 3, and the second part 51 of the first radiator 2 has the same shape as the second part 52 of the second radiator 3.

[0037] In an embodiment, the first part 4 (41, 42) is semicircular, which can mean that the first part 4 (41, 42) includes a diameter edge and an arc edge, and the length of the diameter edge is the diameter of the semicircle. The second part 5 (51, 52) can be a polygon, such as a rectangle, a trapezoid, a triangle, etc. The second part 5 (51, 52) includes at least one straight edge (i.e., the first straight edge), which is connected to the diameter edge of the first part 4 (41, 42).

[0038] In an embodiment, the first part 4 (41, 42) and the second part 5 (51, 52) are connected by the diameter edge and the first straight edge, and the first part 4 (41, 42) and the second part 5 (51, 52) are integrally connected. For example, as shown in Figure 1 As shown in FIG. 5, the second part 5 (51, 52) is a rectangle, and optionally, the second part 5 (51, 52) can also be a trapezoid, a triangle, or other shapes, which are not limited here.

[0039] In an embodiment, as shown in Figure 2 As shown in FIG. 6, the second part 5 (51, 52) can also be a trapezoid, and the first straight edge connected to the diameter edge can be the long bottom edge of the second part 5 (51, 52), or can also be the short bottom edge of the second part 5 (51, 52), so as to satisfy the characteristic impedance of the antenna changing gently with frequency, and realize the impedance matching characteristic of the radiator.

[0040] In an embodiment, the length of the first straight edge can be equal to the diameter edge, or can also be greater than or less than the diameter edge. For example, when the length of the first straight edge is less than the diameter edge, the second part 5 (51, 52) can be a trapezoid, and the first straight edge is the long bottom edge of the second part 5 (51, 52), so as to extend from the second part 5 (51, 52) to the first part 4 (41, 42) to gradually widen, which is beneficial to gently perform impedance matching.

[0041] In one embodiment, the first radiator 2 and the second radiator 3 are respectively arranged at the upper and lower regions of the substrate 1. The first radiator 2 and the second radiator 3 can be oppositely arranged, i.e. the first radiator 2 and the second radiator 3 are oppositely directed. For example, the opening direction of the first portion 41 of the first radiator 2 is opposite to that of the first portion 42 of the second radiator 4, which can refer to the direction in which the vertex of the arc edge of the first portion 41 of the first radiator 2 points to the diameter edge, which is opposite to the direction in which the vertex of the arc edge of the first portion 42 of the second radiator 4 points to the diameter edge. The diameter edge of the first radiator 2 is parallel to the diameter edge of the second radiator 3, and the first portion 41 of the first radiator 2 is close to the second portion 52 of the second radiator 3.

[0042] For example, the arc edge of the first radiator 2 is close to the arc edge of the second radiator 3, and the diameter edge of the first portion 41 of the first radiator 2 is away from the diameter edge of the first portion 42 of the second radiator 3. Here, the arc edge of the first radiator 2 can refer to the arc edge of the first portion 41 of the first radiator 2, and the arc edge of the second radiator 3 can refer to the arc edge of the first portion 42 of the second radiator 3.

[0043] In one embodiment, the arc edge of the first radiator 2 is close to the arc edge of the second radiator 3, which can refer to the distance between the vertex of the arc edge of the first radiator 2 and the vertex of the arc edge of the second radiator 3, which is the minimum distance between any point on the first radiator 2 and any point on the second radiator 3. Here, the vertex of the arc edge refers to the point on the arc edge of the first portion 4 (41, 42) farthest from the diameter edge.

[0044] In one embodiment, the second portion 51 of the first radiator 2 and the second portion 52 of the second radiator 3 are respectively close to the upper edge and the lower edge of the substrate 1, and the first portion 41 of the first radiator 2 is close to the first portion 42 of the second radiator 3.

[0045] In one embodiment, the opening direction of the first portion 41 of the first radiator 2 can be directed to the upper edge of the substrate 1, and the opening direction of the first portion 42 of the second radiator 3 can be directed to the lower edge of the substrate 1.

[0046] In one embodiment, the first radiator 2 and the second radiator 3 are mirror-symmetrical, which can refer to that the first radiator 2 and the second radiator 3 are mirror-symmetrical based on the transverse central axis of the substrate 1. Here, the transverse central axis can be the central axis that equally divides the substrate 1 into an upper half region and a lower half region.

[0047] In one embodiment, the diameter edge of the first portion 4 (41, 42) is parallel to the width direction of the substrate 1, i.e. the transverse central axis direction of the substrate 1. The length of the diameter edge of the first portion 4 (41, 42) can be equal to or less than the width of the substrate 1, and the length of the first straight edge of the second portion 5 (51, 52) can be equal to the length of the diameter edge.

[0048] Thus, based on the two radiators symmetrically arranged in the upper and lower regions of the substrate 1, and each having a semi-circular structure, the currents of the upper and lower radiators can be kept in the same direction over the ultra-wideband range. The omnidirectional radiation characteristics of the antenna are achieved based on the two semi-circular structures with opposite directions. In addition, based on the second part 5 (51, 52) extending from the semi-circular structure, the characteristic impedance of the antenna can be kept smooth and stable with frequency changes, realizing the ultra-wideband impedance matching characteristics of the radiators and improving the radiation efficiency of the antenna.

[0049] In some embodiments, the second portion 5 (51, 52) is a rectangle, and the first straight side has the same length as the diameter side.

[0050] Here, as Figure 1 As shown, based on the first straight side and the diameter side of the same length, the second part 5 (51, 52) of the rectangular shape is integrally connected with the first part 4 (41, 42) of the semicircular shape.

[0051] In one embodiment, the first straight side is the long side of the rectangle, i.e., the second part 5 (51, 52).

[0052] In one embodiment, the second portion 5 (51, 52) is close to the edge of the substrate 1. For example, the second portion 51 of the first radiator 2 is close to the upper edge of the substrate 1, and the second portion 52 of the second radiator 3 is close to the lower edge of the substrate 1.

[0053] In one embodiment, the side of the second part 5 (51, 52), i.e. the short side of the rectangle, is close to the left and right edges of the substrate 1. For example, it may coincide with the left and right edges, or the distance from the left and right edges may be less than a preset value, thereby improving the coverage of the antenna radiator.

[0054] Thus, based on the overlap of the first straight side and the diameter side and the extension from the first part 4 (41, 42) to the second part 5 (51, 52), the characteristic impedance of the radiator can be better maintained to change smoothly with frequency, thereby realizing the ultra-wideband impedance matching characteristics of the radiator.

[0055] In one embodiment, the second straight edge of the second portion 5 (51, 52) that is parallel to the first straight edge is close to the edge of the substrate 1.

[0056] Here, the second straight side is parallel to the first straight side. For example, when the second part 5 (51, 52) is a trapezoid, the first straight side is the long base and the second straight side is the short base; or, when the second part 5 (51, 52) is a rectangle, both the first straight side and the second straight side are long sides.

[0057] In one embodiment, the lengths of the first straight side and the diameter side are positively correlated with the operating frequency band of the antenna.

[0058] In one embodiment, the lengths of the first straight side and the diameter side are equal. The lengths of the first straight side and the diameter side may be positively correlated with the operating frequency band and are related to the material of the substrate 1.

[0059] For example, depending on the adjustment of the operating frequency band and the selection of the substrate, the length range of the first straight side and the diameter side can be 60mm to 120mm.

[0060] In one embodiment, the length of the first straight edge and the diameter edge is 96 mm, and the width of the second portion along the direction perpendicular to the first straight edge is 18 mm.

[0061] Preferably, the length of the first straight side is 96mm, and when the second part 5 (51, 52) is a rectangle, the side length of the second part 5 can be 18mm.

[0062] In this way, a radiator of a certain size can be selected according to the operating frequency band, which is conducive to providing accurate omnidirectional radiation capability for the required frequency band.

[0063] Figure 3 This is a schematic diagram of an antenna structure provided in this embodiment, as shown below. Figure 3 As shown, the antenna may further include a feeding assembly 6 connected to the first radiator 2.

[0064] In one embodiment, the first radiator 2 is disposed in the upper half of the front side of the substrate 1, the power supply component 6 is disposed in the lower half of the front side of the substrate 1, and the second radiator 3 is disposed in the lower half of the back side of the substrate 1.

[0065] In one embodiment, the power feeding component 6 is used to feed power to the first radiator 2. For example, the power feeding component 6 can be a microstrip power feeding component 6, etc. The power feeding component 6 is disposed on the front side of the substrate 1 where the first radiator 2 is located. For example, the power feeding component 6 is disposed in the lower half region, and the power feeding component 6 can be connected to the first part 41 of the first radiator 2.

[0066] In one embodiment, such as Figure 3 As shown, the solid line represents the first radiator 2 and the power supply assembly 6 disposed on the front side of the substrate 1, and the dashed line represents the second radiator 3 disposed on the back side of the substrate 1. The power supply assembly 6 can be connected to the apex of the arc edge of the first part 41 in the first radiator 2.

[0067] Thus, to avoid the first radiator 2 being connected to the power supply component 6, which would prevent the second radiator 3 from being installed on the front side at the same time, the second radiator 3 is installed on the back side and kept in mirror symmetry with the first radiator 2. This will not affect the power supply process and will maintain the omnidirectional effect produced by the mirror symmetrical upper and lower radiators.

[0068] In one embodiment, such as Figure 4 As shown, the length direction of the power supply component 6 is perpendicular to the diameter side of the first portion 4 (41, 42); the width of the power supply component 6 gradually increases along the direction away from the first radiator 2. Here, "gradually increasing width along the direction away from the first radiator 2" can mean that the width of the power supply component 6 is larger at positions farther away from the first radiator 2.

[0069] In one embodiment, one end of the power supply component 6 may be connected to the arc edge of the first portion 41 of the first radiator 2, for example, to the vertex of the arc edge. The power supply component 6 may be a strip structure, the length direction of which is perpendicular to the diameter side of the first portion 4 (41, 42), and the width of the strip structure increases with the distance from the first radiator 2.

[0070] In one embodiment, the power supply component 6 can be a triangle or a trapezoid, and the upper vertex of the triangle or the short base of the trapezoid can be connected to the arc edge of the first part 4 (41, 42), for example, connected to the vertex of the arc edge.

[0071] In one embodiment, the maximum width of the feed assembly 6 can be 2–5 mm. For example, the maximum width is the width of the feed assembly 6 at its furthest point from the first radiator 2. Exemplarily, if the feed assembly 6 is trapezoidal, the maximum width is the width of its base; or, if the feed assembly 6 is triangular, the maximum width is the width of the base opposite the top vertex. This gradual increase in width allows for good solderability, such as allowing for the soldering of SMA connectors, thereby ensuring the mechanical reliability of the antenna.

[0072] In one embodiment, the power supply component 6 is divided into multiple sections, and the maximum width of the section farther away from the first radiator 2 is larger.

[0073] Here, each section can be either a trapezoid or a rectangle. When a section is a trapezoid, its maximum width is the width of its longer base; when a section is a rectangle, its maximum width is the width of the rectangle.

[0074] In one embodiment, the width of each segment increases as the distance between the segment and the first radiator 2 increases. For example, when a segment is trapezoidal, the shorter base of the trapezoid is closer to the first radiator 2, and the longer base is farther away from the first radiator 2.

[0075] In one embodiment, when a segment is trapezoidal, it can connect to the previous segment via its short base and to the next segment via its long base. Here, the previous segment refers to the segment closer to the first radiator 2, and the next segment refers to the segment farther from the first radiator 2. The length of the side connecting the previous segment to this segment can be equal to the length of the short base of this segment, and the length of the side connecting the next segment to this segment can be equal to the length of the long base of this segment.

[0076] In one embodiment, the feeding assembly 6 is divided into a first section 61, a second section 62, a third section 63, a fourth section 64 and a fifth section 65 in the direction away from the first radiator 2; wherein the maximum width of the first section 61 is 1.0 mm, the maximum width of the second section 62 is 1.4 mm, the maximum width of the third section 63 is 1.5 mm, the maximum width of the fourth section 64 is 1.9 mm, and the maximum width of the fifth section 65 is 2.7 mm.

[0077] In this way, based on the gradually increasing width of the feeding structure design, the radiation unit of the ultra-wideband can be matched, and the entire network can be gradually matched in a wide frequency band to keep very low reflection loss and ensure transmission efficiency, thereby achieving ultra-wideband feeding for the radiation unit.

[0078] In one embodiment, as shown in FIG. 1, the feeding assembly 6 is divided into a plurality of sections, each section has a consistent width, and the farther the section is from the first radiator 2, the greater the width of the section. Figure 5

[0079] In one embodiment, each section is rectangular, each section has a consistent width, which is the width of the rectangular section. The width is the width of the section along the transverse central axis of the substrate 1, and the length is the length of the section along the direction perpendicular to the transverse central axis.

[0080] In one embodiment, the feeding assembly 6 can be divided into a first section 61, a second section 62, a third section 63, a fourth section 64 and a fifth section 65 in the direction away from the first radiator 2. For example, the length of the first section 61 ranges from 8 to 16 mm, and the width ranges from 0.5 to 3 mm; the length of the second section 62 ranges from 8 to 16 mm, and the width ranges from 1 to 3.5 mm; the length of the third section 63 ranges from 8 to 16 mm, and the width ranges from 1 to 3.5 mm; the length of the fourth section 64 ranges from 20 to 28 mm, and the width ranges from 1.5 to 4 mm; the length of the fifth section 65 ranges from 5 to 10 mm, and the width ranges from 2 to 5 mm.

[0081] For example, the width of the first section 61 is 1.0 mm, the width of the second section 62 is 1.4 mm, the width of the third section 63 is 1.5 mm, the width of the fourth section 64 is 1.9 mm, and the width of the fifth section 65 is 2.7 mm.

[0082] For example, the length of the first section 61 is 12 mm, the length of the second section 62 is 12 mm, the length of the third section 63 is 12 mm, the length of the fourth section 64 is 24 mm, and the length of the fifth section 65 is 8.2 mm.

[0083] ​Thus, the multi-stage feeding circuit is formed by the design of the plurality of sections, each stage of the feeding circuit is matched step by step, the whole network keeps very low reflection loss, the transmission efficiency of the transmission line is ensured in the ultra-wideband range, and thus the radiation efficiency of the antenna is improved.

[0084] As a possible implementation, an antenna is provided, as shown in the drawings, which respectively represent the overall, front and back schematic diagrams of the antenna. Specifically, it comprises: Figure 6

[0085] 1. Rectangular + semi-circular radiator, specifically, the front and back radiator structures are mirror-symmetrical; by adopting the rectangular + semi-circular radiator structure, the following technical effects are achieved:

[0086] 1) The characteristic impedance of the radiator changes smoothly with frequency, realizing the ultra-wideband impedance matching characteristic of the radiator;

[0087] 2) The radiator can keep the current of the upper and lower radiators in the same direction in the ultra-wideband range, realizing the omnidirectional radiation characteristic of the antenna;

[0088] Exemplarily, the typical size is: rectangular size 96mm*18mm, and the semi-circular diameter is 96mm. With the adjustment of the working frequency band and the selection of the base material, the semi-circular diameter range can be dynamically adjusted from 60mm to 120mm.

[0089] 2. Five-stage ultra-wideband microstrip feeding structure, specifically:

[0090] 1) Matching the ultra-wideband radiation unit, realizing the ultra-wideband feeding of the radiation unit;

[0091] 2) The feeding structure gradually widens from top to bottom, and the width of the last section reaches 2.5mm, realizing good solderability, and the SMA connector can be soldered, ensuring the mechanical reliability of the antenna;

[0092] 3) Each stage of the feeding circuit is matched step by step, the whole network keeps very low reflection loss, the transmission efficiency of the transmission line is ensured in the ultra-wideband range, and thus the radiation efficiency of the antenna is improved.

[0093] Exemplarily, the typical size is:

[0094] 1 section: 12mm*1mm, the length range is 8-16mm, and the width range is 0.5-3mm;

[0095] 2 section: 12mm*1.4mm, the length range is 8-16mm, and the width range is 1-3.5mm;

[0096] 3 section: 12mm*1.5mm, the length range is 8-16mm, and the width range is 1-3.5mm;

[0097] ​4th section: 24mm*1.9mm, length range is 20~28mm, width range is 1.5~4mm;

[0098] 5th section: 8.2mm*2.7mm, length range is 5~10mm, width range is 2~5mm.

[0099] Based on the antenna design of the above embodiments, the impedance matching effect as shown in Figure 7 , and the horizontal plane 2D pattern as shown in Figure 8 , have very good omni-directional effect in the super wide frequency band, and have higher radiation efficiency in the super wide band.

[0100] In one embodiment, an electronic device is also provided, comprising the antenna of any one or more of the preceding embodiments.
