Embodiment Construction
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0035] It should be noted that if there are directional indications such as up, down, left, right, front, back, etc. in the embodiment of the present invention, the directional indications are only used to explain the position of each individual in a certain posture as shown in the attached figure. If the relative positional relationship, movement conditions, etc. between the components change, the directional indication will also change accordingly...

The invention discloses a dielectric lens, an antenna and application of the dielectric lens and the antenna, the dielectric lens comprises a lens body, the lens body is a solid sphere or a hemisphere, and the lens body is made of a uniform insulating material. According to the scheme, the lens body is solid spherical or hemispherical and is made of the uniform insulating material, the dielectricconstants are kept consistent, and after a feed source emits electromagnetic waves outside the lens body, the electromagnetic waves emitted by the feed source can be converted into planar electromagnetic waves through the conversion of the lens body so as to obtain wave beams with higher directivity; moreover, the antenna gain is improved, and the antenna also has the advantages of small side lobeand back lobe, good directivity and the like. Different from the Luneberg lens realized by changing the dielectric constant of the internal material or the equivalent dielectric constant of the structure, the lens body can be realized by only one uniform material and can be formed at one time, the manufacturing mode is simple, the manufacturing cost is relatively low, and the industrial production is facilitated; and the lens body is especially suitable for microwave and millimeter wave communication application.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a dielectric lens, an antenna and applications thereof. Background technique [0002] With the continuous development of society, people's demand for wireless communication is also increasing, and the frequency of electromagnetic waves used is gradually tending to the millimeter wave frequency band. Millimeter waves have a shorter working wavelength, which can effectively reduce the size of components and systems. Due to the short wavelength, millimeter waves also have higher resolution in radar, imaging, etc.; in addition, millimeter waves can provide Larger bandwidth and higher data rate have attracted extensive attention from the communication industry in recent years. [0003] However, in addition to the above advantages, millimeter waves also have disadvantages such as large propagation loss and small coverage. Therefore, in order to realize the long-distance transmission...
