[0060] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0061] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0062] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0063] As used herein, "parallel" and "perpendicular" include the conditions described and conditions similar to the conditions described, and the range of the similar conditions is within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0064] Exemplary embodiments are described herein with reference to cross-sectional and / or plan views that are idealized exemplary drawings. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include deviations in shape due to, for example, manufacturing. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of regions of the device and are not intended to limit the scope of the exemplary embodiments.
[0065] A lens antenna consists of a lens body and a feed. The lens body, such as a Luneburg lens structure, primarily focuses the beam. The feed is located on one side of the lens body and is used to transmit and receive electromagnetic waves. The feed includes antenna structures such as a vibrator, reflector, electronically adjustable components, and a feed network.
[0066] For example, a lens antenna consists of a first housing and a lens within it, as well as a second housing and its internal components, such as a vibrator and phase shifter. The second housing is fixed to the first housing to form a single radome. This results in a larger overall size for the lens antenna and makes installation, transportation, disassembly, and maintenance difficult.
[0067] In order to solve the above problems, an embodiment of the present disclosure provides a lens antenna, which includes: a first shell and a lens located in the first shell, and also includes a fixing bracket, a second shell, and a feed source located in the second shell. The second shell is located on one side of the first shell and is independent of the first shell; the feed source is located in the second shell and is used to transmit electromagnetic waves to the lens body or receive electromagnetic waves from the lens body; the first shell and the second shell are both detachably connected to the fixing bracket. By independently arranging the first shell and the second shell, the embodiment of the present disclosure can reduce the overall volume of the lens antenna and facilitate installation and disassembly. In addition, the discrete structure also has the advantages of flexible matching and high consistency of antenna oscillators.
[0068] Table 1 shows the gain simulation results for a lens antenna with a separate first and second housing in the disclosed embodiment, while Table 2 shows the gain simulation results for a lens antenna with an integrated first and second housing. As can be seen from Tables 1 and 2, the gain of the lens antenna with a separate structure is 0.5 to 1 dBi higher than that of the integrated lens antenna.
