Description

Technical Field

[0001] This invention relates to lens technology, and more particularly to a method, apparatus, electronic device, and storage medium for manufacturing a lens antenna. Background Technology

[0002] Current traditional array antennas require an increased number of antennas for high-gain, narrow-beam applications, leading to increased physical size and weight. Lens antennas, on the other hand, can achieve narrow beams by changing the focal length.

[0043] The accompanying drawings illustrate exemplary embodiments of this application, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0044] like Figure 1 As shown in the figure, this application embodiment provides a method for manufacturing a lens antenna, the method comprising:

[0045] Step 101: Determine the first attribute of the first lens and the second attribute of the second lens, wherein the first attribute includes a first chromatic difference value and the second attribute includes a second chromatic difference value.

[0046] In this embodiment, the first lens is preferably a Fresnel phase lens, and the second lens is preferably a Fresnel lens. A Fresnel lens is composed of a series of concentric rings resembling a spiral pattern, also known as a spiral lens. Fresnel lenses are used for focusing and collimating light and are smaller in size than traditional lenses. The effective thickness of a Fresnel lens is the same across its entire diameter. This uniform thickness significantly reduces weight compared to a glass lens of the same focal length and diameter, making it ideal for building small optical systems. The shorter the signal wavelength of a conventional Fresnel lens, the more pronounced the focusing effect; this dispersion effect is called "positive dispersion." Similar to Fresnel lenses, the longer the signal wavelength of a Fresnel phase lens, the more pronounced the focusing effect; this dispersion effect is called "negative dispersion." First, the lens material, communication frequency band, refractive index, and other properties of the first and second lenses are determined, and then the chromatic difference values ​​of the first and second lenses are determined.

[0047] Step 102: Iterate according to the preset initial iteration value, the first color difference value and the second color difference value, and update the initial iteration value.

[0048] In this embodiment, an initial iteration value is first set, and the absolute values ​​of the first and second color difference values ​​are compared. The focal lengths of the first and second lenses are then re-determined based on the comparison result. For example, by setting the initial iteration value to 10, the initial iteration value is decreased by 1 each time the first and second color difference values ​​are compared, until the initial iteration value is 0, at which point the iteration stops.

[0049] Step 103: Given the initial iteration value as the target value, obtain the first focal length corresponding to the first lens and the second focal length corresponding to the second lens. The lens antenna includes the first lens and the second lens arranged in parallel. The distance between the first lens and the second lens is based on the first focal length and the second focal length.

[0050] In this embodiment, the target value is 0. When the initial iteration value is the target value, the first focal length corresponding to the first lens and the second focal length corresponding to the second lens are calculated, and the first lens and the second lens are combined into a lens antenna. Specifically, the lens antenna is as follows: Figure 2 As shown, a Fresnel lens is positioned parallel to the feed source, and a Fresnel phase mirror is positioned after the Fresnel lens. The distance between the first lens and the second lens is determined based on the first focal length and the second focal length.

[0064] Optionally, the step of redetermining the first focal length based on the initial iteration value includes:

[0065] Obtain the target focal length of the lens antenna;

[0066] The first focal length is determined based on the initial iteration value and the target focal length.

[0067] In this embodiment, the initial iteration value K is first set. In this embodiment, K is set to 10. F is then set. a =F1 and F b =2F1, where F1 is the target focal length of the target lens antenna. At this point, compare the absolute values ​​of the first and second chromatic difference values. If |δF p |<|δF f |, then take the focal length F of the first lens. f =(F a +F b ) / 2, thus calculating the focal length F of the second lens. f =(F a +F b ) / 2, calculate If K is greater than 0, and |δF p |<|δF f |, then K is reduced by 1, at which point F b =(F a +F b ) / 2, F a =(F a +F b ) / 2 and calculate Until K is 0.

[0068] Optionally, the step of iterating based on a preset initial iteration value, the first color difference value, and the second color difference value to update the initial iteration value includes:

[0069] If the absolute value of the first color difference is greater than the absolute value of the second color difference, then the second focal length is re-determined based on the preset initial iteration value;

Then, the absolute values ​​of the first and second chromatic difference values ​​are compared. When K > 0, |δF p |>|δF f |At this time, F b =(F a +F b ) / 2, F a =(F a +F b If F = 2 / 2, then F p =(F a +F b ) / 2, calculate Until the value of K equals 0.
