Problems solved by technology

[0004] Although the Luneburg lens has a relatively good vertical and horizontal direction diagram, the profile shape of the cross-section of the beam is theoretically circular, so when the signals of multiple Luneburg lens antennas are used to cover a certain site, these The signals of Lunberg lens antennas inevitably need to overlap in a large area to ensure that there is no "blind area" in the target site, which is equivalent to using more Lunberg lens antennas to ensure that there is no "blind area" in the target site. is to increase the construction cost

Abstract

The invention provides an electromagnetic wave lens. An outline shape of a cross section of a wave beam passing through the lens is similar to a rectangle or a square so that blind-area-free signal coverage can be realized by using the least lens antennas. A kernel body and a plurality of dielectric layers wrapping the kernel body are included. A dielectric constant of the kernel body is 1.7-2.3,the dielectric constant of the dielectric layer on the outermost layer is 1-1.2, and the dielectric constants of all the layers are smaller and smaller from the kernel body to the dielectric layer onthe outermost layer. Especially, the kernel body is a cuboid, and an appearance of each dielectric layer is also a cuboid. In fact, debugging personnel can complete debugging work of ground coverage more simply and accurately under a condition of avoiding large-area overlapping of different wave beams. The invention also provides an antenna adopting the electromagnetic wave lens and an electromagnetic wave lens antenna array.

Description

technical field [0001] The invention relates to the field of communication equipment production, more specifically, to a lens used to control the propagation direction of electromagnetic waves and the lobe boundary shape of electromagnetic waves, an antenna using the lens, and an antenna array. Background technique [0002] Electromagnetic wave lens is a passive device that can converge electromagnetic waves. One of the structural forms of electromagnetic wave lenses is the famous Lunberg lens. [0003] Antenna oscillators combined with Lunberg lenses can be made into Lunberg lens antennas. Lunberg lens antennas have the advantages of small side lobes and back lobes, good pattern, high gain, and no need for complex calculations. These advantages are when the antenna oscillator operates at high frequencies When the time is high, such as the current 5G communication frequency band or even the future 6G communication frequency band, the effect it can achieve is even beyond the...
