[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] It should be noted that, unless otherwise specified, the various features in the embodiments of the present invention can be combined with each other, and all are within the protection scope of the present invention. Furthermore, although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different module division or in a different order than that shown in the device schematic diagram or the flowchart.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0036] Resonators can resonate at specific frequencies, exhibiting higher response and transmission efficiency for signals of that frequency in a resonant state, enabling precise signal conversion and filtering. Dielectric resonator antennas (DRAs) are antennas that generate electromagnetic waves using the inherent resonant characteristics of the antenna itself. They are compact, lightweight, and low-cost, compatible with various feeding methods, and possess good resonant characteristics and radiation efficiency. Introducing dielectric resonator antennas into resonator design reduces the size and cost of the resonator while simultaneously improving its performance based on the resonant characteristics of the dielectric resonator antenna.

[0037] Furthermore, the performance of a resonator can be further improved by increasing the gain of a single dielectric resonator antenna. There are three existing methods for increasing the gain of a single dielectric resonator antenna. The first method is to increase the gain through arraying, that is, to combine multiple dielectric resonator antennas in a specific array to increase the overall gain, but this increases the number of elements and complicates the feeding network. The second method is to increase the gain through higher-order mode dielectric resonators, but the higher the order of the rectangular dielectric resonator antenna, the higher the processing precision required, and therefore the larger the size. The third method is to increase the gain by adding parasitic dielectric resonator antennas, but a complete theoretical method is lacking.

[0038] When increasing the gain of a dielectric resonator antenna, the distance between the parasitic antenna and the feed antenna is a crucial factor affecting the resonant frequency, operating bandwidth, and gain. Arbitrarily setting this distance can lead to resonant frequency misalignment and insufficient bandwidth, limiting its applicability and controllability. Therefore, a design method for parasitic dielectric resonators is needed to select appropriate parasitic parameters based on the specific application scenario and requirements.

[0039] Please see Figure 1 , Figure 1 This is a flowchart illustrating a design method for a parasitic dielectric resonator according to an embodiment of the present invention. The design method for the parasitic dielectric resonator includes:

[0040] S11. Obtain the field distribution of the dielectric resonator antenna to determine the parasitic migration range. Here, the field distribution represents the electric field distribution within the xoy plane of the dielectric resonator antenna, the xoy plane represents the plane containing the radiation direction of the dielectric resonator antenna, and the parasitic migration range represents the migration range of the parasitic antenna within the dielectric resonator antenna. Please refer to [link / reference]. Figure 2 , Figure 2This is a flowchart of a method for determining the parasitic mobility range provided in an embodiment of the present invention. The step of obtaining the field distribution of the dielectric resonator antenna to determine the parasitic mobility range includes:

[0041] S111. Obtain the field distribution of the dielectric resonator antenna. This can be achieved through simulation analysis to obtain the field distribution information of the dielectric resonator antenna. Please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic diagram of the electric field distribution in the xoy plane of the dielectric resonator antenna provided in an embodiment of the present invention. Figure 3 It can be seen that the electric field distribution in the xoy plane of the dielectric resonator antenna includes not only the internal field but also the external leakage electric field. The internal field refers to the electric field distribution formed in the structure of the dielectric resonator antenna itself, that is, the electric field distribution excited by the feed antenna in the dielectric resonator antenna. The external leakage electric field refers to the electric field distribution generated by the secondary radiation due to the presence of the parasitic antenna in the dielectric resonator antenna.

[0042] S112. Obtain the maximum electric field value and the leakage electric field value corresponding to different spacings based on the field distribution. Obtain electric field intensity distribution data according to the field distribution information, change the distance from the parasitic antenna to the feed antenna, and record the electric field intensity distribution data at different distances to obtain the leakage electric field value corresponding to different spacings. Wherein, the maximum electric field value represents the maximum electric field intensity value in the field distribution of the dielectric resonator antenna.

[0043] S113. Plot the spacing-leakage field coefficient curve based on the maximum electric field value and the leakage electric field values ​​corresponding to different spacings. (See also...) Figure 4 , Figure 4 This is a schematic diagram of the spacing-leakage field coefficient curve provided in an embodiment of the present invention. The horizontal axis represents the distance from the parasitic antenna to the feed antenna, and the vertical axis represents the ratio of the leakage electric field to the maximum electric field value. The schematic diagram of the spacing-leakage field coefficient curve is a normalized coefficient diagram of the ratio of the leakage electric field to the maximum electric field value of the dielectric resonator antenna.

[0044] S114. Determine the parasitic migration range based on the aforementioned spacing-leakage field coefficient curve. For example... Figure 4 It can be seen that the leakage electric field only exists within a distance of 0-5mm between the parasitic antenna and the feed antenna, that is, the parasitic movement range is 0-5mm.

[0045] S12. Obtain the influence curves based on the parasitic movement range. The influence curves include the influence curves of spacing on gain, spacing on resonant frequency, and spacing on operating bandwidth. The spacing is the distance from the parasitic antenna to the feed antenna in the dielectric resonator antenna.

[0046] Please see Figure 5 , Figure 5This is a flowchart of a method for obtaining an influence curve according to an embodiment of the present invention. The step of obtaining the influence curve based on the parasitic movement range includes:

[0047] S121. Based on the parasitic movement range, obtain the gain, resonant frequency, and operating bandwidth of the dielectric resonator antenna corresponding to different spacings. Specifically, during simulation analysis, the distance from the parasitic antenna to the feed antenna is continuously changed within the parasitic movement range, and the gain, resonant frequency, and operating bandwidth corresponding to different spacings are recorded.

[0048] S122. Draw the spacing-gain curve according to the gain corresponding to different spacings.

[0049] S123. Draw the spacing-working bandwidth curve according to the working bandwidth corresponding to different spacings.

[0050] Please see Figure 6 , Figure 6 This is a schematic diagram of the spacing-gain curve and the spacing-operating bandwidth curve provided in the embodiments of the present invention. Based on the recorded gains corresponding to different spacings, a spacing-gain curve is plotted with the distance from the parasitic antenna to the feed antenna as the horizontal axis and the gain as the vertical axis; based on the recorded operating bandwidths corresponding to different spacings, a spacing-operating bandwidth curve is plotted with the distance from the parasitic antenna to the feed antenna as the horizontal axis and the operating bandwidth as the vertical axis.

[0051] S124. Plot the spacing-resonance frequency curves based on the resonant frequencies corresponding to different spacings. Please refer to [link / reference]. Figure 7 , Figure 7 This is a schematic diagram of the spacing-resonance frequency curve provided in the embodiment of the present invention. Based on the recorded resonance frequencies corresponding to different spacings, a spacing-resonance frequency curve is plotted with the distance from the parasitic antenna to the feed antenna as the horizontal axis and the resonance frequency as the vertical axis.

[0052] S13. Determine the target parasitic parameters based on the influence curve. The target parasitic parameters represent the optimal distance from the parasitic antenna to the feed antenna. (See also...) Figure 8 , Figure 8 This is a flowchart of a method for determining target parasitic parameters based on an influence curve, provided by an embodiment of the present invention. Determining the target parasitic parameters based on the influence curve includes:

[0053] S131. Obtain the application frequency band of the parasitic dielectric resonator. The application frequency band can be set according to actual conditions and specific needs; this invention does not impose specific limitations on it. For example, the dielectric resonator antenna of the parasitic dielectric resonator can be applied to the N260 (37-40GHz) frequency band of 5G.

[0054] S132. Determine the range of the spacing based on the spacing-resonance frequency curve and the application frequency band. For example, when the dielectric resonator antenna of the parasitic dielectric resonator is applied to the N260 (37-40GHz) frequency band of 5G, it can be achieved through... Figure 7 ,Right now Figure 10 As shown in the spacing-resonant frequency curve diagram, the distance between the parasitic antenna and the feed antenna ranges from 0.3-1.9mm and 3-5mm.

[0055] S133. Determine the target parasitic parameters based on the spacing-gain curve, the spacing-operating bandwidth curve, and the range of the spacing. (See also...) Figure 9 , Figure 9 This is a flowchart of a method for determining target parasitic parameters based on a spacing-gain curve, a spacing-operating bandwidth curve, and a spacing range, provided by an embodiment of the present invention. The method for determining target parasitic parameters based on the spacing-gain curve, the spacing-operating bandwidth curve, and the spacing range includes:

[0056] S1331. Determine whether the target performance indicator is operating bandwidth or gain. The target performance indicator represents the most critical indicator pursued by the designer when designing a parasitic dielectric resonator. The most critical indicator includes operating bandwidth and gain. In some other embodiments, the target performance indicator also includes other indicators besides operating bandwidth and gain; any change in spacing can affect this indicator. This embodiment of the invention does not specifically limit this. For example, minimum reflection coefficient. It is understood that if the target performance indicator is the minimum reflection coefficient, a corresponding spacing-minimum reflection coefficient curve should be plotted.

[0057] S1332. If the target performance indicator is the working bandwidth, then a first spacing is determined based on the spacing-working bandwidth curve and the range of the spacing, so as to use the first spacing as the target parasitic parameter.

[0058] S1333. If the target performance index is gain, then a second spacing is determined based on the spacing-gain curve and the range of the spacing, so as to use the second spacing as the target parasitic parameter.

[0059] For example, when the dielectric resonator antenna with the parasitic dielectric resonator is applied to the N260 (37-40GHz) band of 5G, and the distance from the parasitic antenna to the feed antenna is in the range of 0.3-1.9mm and 3-5mm, please refer to [reference needed]. Figure 10 , Figure 10 This is a comparative diagram illustrating the determination of target parasitic parameters based on the spacing-gain curve, the spacing-operating bandwidth curve, and the spacing range, provided by an embodiment of the present invention. If the most critical indicator pursued during design is the operating bandwidth, and the goal is to achieve optimal operating bandwidth (bandwidth), then... Figure 6 ,Right now Figure 10 From the spacing-operating bandwidth curve, it can be seen that the optimal operating bandwidth is achieved when the spacing d is 3-3.3mm within the distance range from the parasitic antenna to the feed antenna. Therefore, the first spacing d obtained is 3-3.3mm, that is, the target parasitic parameter d is 3-3.3mm, and the operating bandwidth is 14.5% at this time. If the most critical indicator pursued in the design is gain, and the goal is to achieve maximum gain, then by... Figure 6 ,Right now Figure 10 As can be seen from the spacing-gain curve, the gain is the largest when d is 0.3mm within the distance range from the parasitic antenna to the feed antenna. Therefore, the second spacing d = 0.3mm is obtained, that is, the target parasitic parameter d = 0.3mm, and the gain is 8.5dBI at this time.

[0060] This invention provides a design method for a parasitic dielectric resonator. The method includes: acquiring the field distribution of the dielectric resonator antenna to determine the parasitic movement range; then, based on the parasitic movement range, acquiring the influence curve of the distance between the parasitic antenna and the feed antenna on the gain, resonant frequency, and operating bandwidth; and finally, determining the target parasitic parameters based on the influence curve. This method allows for the reasonable adjustment of the position of the parasitic dielectric resonator antenna according to requirements, achieving the desired gain and operating bandwidth. It realizes digital control of the dielectric resonator's gain, operating bandwidth, and desired resonant frequency, improving the controllability and applicability of the parasitic dielectric resonator antenna.
